Nearly 20 years ago, the National Institute of Standards and Technology (NIST) established guidelines for secure passwords. Indeed, they are still used by many websites, portals, and other services. You’re likely familiar with these password requirements — there ought to be at least 8 characters, both capital and lowercase letters, digits, and special characters. Despite these guidelines, passwords that meet these requirements are no longer safe from modern attackers. The only thing any of us can do to improve the security of our accounts is to make sure that our passwords are lengthy, complicated, and unique for each account. Due to the strict password management requirements, this strategy is, nevertheless, laborious and intimidating for many.
The same password rules do not apply today
In the modern day, password-based security is no longer seen as sufficient. Our digital world is continuously expanding, thus it is more important than ever to make sure that our data is safeguarded from cybercriminals. Cybercriminals perceive an opportunity to target people in a more sophisticated way as a result of the increasing usage of internet services. One explanation is that, although we benefit from technological improvement for our personal, social, or economic growth, cybercriminals have also benefited from the advantages of improved computer graphics cards and machine learning to enhance their attack strategies. In addition to the problem of more sophisticated cyberattacks, there are two interrelated problems with conventional password rules:
The first concern lies in our human nature — keeping track of passwords is tough
You may take a few steps as an individual to increase the security of your passwords. Start by lengthening and making your passwords more complicated. Second, create a unique password for each website you visit. The difficulty of remembering a password increases with its complexity. As a result, we frequently select passwords that are not entirely suitable yet are simple to remember. The difficulty of managing several complicated passwords for every online account leads to the frequent reuse of the same passwords across multiple platforms. As a result, a successful attacker immediately wins big.
However, the high level of password complexity necessary to maintain online safety should not be blamed; rather, it should be pointed out that we can’t improve our inadequate password management skills. Using a password manager to generate and store secure passwords is a useful solution. It is not humanly possible to manage strong passwords for all of our internet accounts without assistance, such as password managers. Because they can't recall the complicated, random sequences of letters, numbers, and special characters, the problem increases the likelihood that individuals will write down their passwords. Passwords are left exposed in digital files stored on a computer or in desk-top notes, making it simple for hackers to hack and read passwords.
The second problem is that passwords have a mathematical limit
There are only ever a finite amount of potential password combinations since a password is a mix of letters, numbers, and symbols. As a result, the best technique for breaking passwords is brute force attacks. Until the correct combination is identified and the password is broken, brute force attacks attempt all possible combinations of letters, numbers, and symbols. Theoretically, a stronger password would be one that is harder to guess due to its length, complexity, and number of possible permutations. However, attackers are now substantially more frequently exploiting Graphic Processing Units (GPUs) to break passwords. GPUs are a component of a computer's graphics card and were first designed to speed up the loading of images and movies. They now show promise for computing hashes (the method used in brute force attacks).
According to studies on password cracking times, passwords may be cracked much more quickly using sophisticated computer graphics cards. Using the most recent computer graphic cards, an 8-character password that used to take 8 hours to crack in 2018 now only takes 39 minutes (see the conclusive 2022 results in the table below). Passwords are gradually getting simpler to crack as a result of recent technical developments, which is a concerning trend. More crucial, however, is the fact that if a password has already been stolen, repeated across sites, or contains basic phrases, attackers may access your accounts right away, regardless of the complexity of the password or the attacker's graphics card.
Consider a 4-character password made up of all 26 letters in the Latin alphabet (case-insensitive) in order to visualize this mathematical example.
26^4 = 456,976 possible password combinations
The number of viable choices rises to when you include digits, uppercase and lowercase letters, and special characters.
95^4 = 81,450,625 possible password combinations
However, because the password must contain at least one special character, one number, one capital letter, and one lowercase letter, the quantity drops to
5,353,920 possible password combinations.
Nevertheless, assuming there are no password-entry security measures, this can be cracked in less than a second by a computer (such as automatic account blocking).
Increase the length and complexity of passwords
Longer or more complicated password phrases are strongly advised when creating new passwords. In this manner, potential attackers will have a harder time breaking the codes. It's crucial to take into account the popularity of the selected password combination in addition to the amount of alternative password combinations. For instance, lists of frequently used passwords or phrases, such as "qwerty," "password," or "12345," are frequently used in brute force assaults.
Therefore, the password should be completely unique or not contain any words at all. For instance, one technique would be to employ acronyms or mnemonics, such as generating a password out of the first few characters of a long text. As an illustration, consider making the password ‘Ilts@7S!’ out of the words I love to ski at Seven Springs.
Password length and complexity alone are insufficient
We are aware that adding length and complexity to passwords is the only method to increase their strength and, consequently, the safety of our accounts. The time it typically takes an attacker to break a password in 2022 using a powerful commercial computer is displayed below. This chart, which has been analysed and periodically updated since 2018, shows how quickly passwords can be broken on current machines. This pattern indicates that, despite our best efforts to create passwords that are longer and more complicated, passwords alone are no longer sufficient to meet the required internet security standards.
In conclusion, password rules increase the complexity of passwords without necessarily enhancing their security.
Whenever the word ‘cybersecurity’ appears, the word ‘password’ springs to mind in parallel. People use them everywhere, from mobile phone locks to the protection of personal and state data stored on individual devices or websites. Everyone knows that a strong and secure password is able to save our sensitive information, however, cybercriminals have invented a huge variety of methods to hack our passwords in order to compromise us. So, modern problems require modern solutions. Now, there are a lot of alternative ways to protect access to personal data. The usual passwords are replaced by multi-layer authentication or just more progressive technologies. These are fingerprints and face recognition functions, keychains, and password vaults. But what is the future of passwords? Will they become an outdated option or stay a necessary part of access.
Why are passwords considered weak?
With the growth of cybercrime, the requirements for passwords are increasing. The first passwords consisted of short, easily-memorized word or numeral combinations, but they were too easy to crack. Now, passwords are sophisticated alpha-numeral combinations, sometimes too long to remember. Nevertheless, it is still possible for hackers to find the solution and get access to your account. Passwords are usually based on some common information like a date of birth, the name of a child, or a home pet, which implies that hackers are able to find out what it is if they have enough time. The other reason why passwords become targets is the fact that they provide unrestricted access to your account. Moreover, many people use the same or similar passwords for many different accounts, so they simplify the process of collecting their sensitive data from multiple sources. Of course, using the same password for every account mitigates the risk of forgetting the password, but reusing the combination is quite risky. Users are sure that they won’t be hacked as the data they store is not valuable enough to be stolen, but it’s a common mistake as almost everyone can be compromised or fall victim to a bot attack that is aimed at spreading spam or malicious links. So, the best way to protect your privacy is not to reuse the same password and exploit multi-layer authentication for your accounts.
The anti-password movement
This movement was established as soon as people understood that usual passwords are more vulnerable than they should be. Passwords are inconvenient and provide multiple avenues for fraudsters to obtain your data and profit from it. The most typical method for hackers to profit from this data is to sell it on the dark web for fast cash. Advanced attacks on logins have been known to shut down entire corporations or launch ransomware campaigns. Credential stuffing is the most well-known form of password hacking, it is based on the reusing of the same password for multiple accounts, pairing it with different email addresses or logins. It is usually aimed at taking over as much information from corporate accounts as possible. Thus, internet users realized that passwords are not the most powerful protection that can be exploited for security goals. So, what was made in addition to, or in place of, the password?
Multi-factor authentication
Single-factor authentication refers to the requirement of only one password to access an account. This method of protection has been used for a long time, but now it’s obsolete. The new practice in authentication is multi-factor access which requires passing two or more layers of authentication before accessing an account. The possible steps of this sophisticated technology could be the PIN code, the server-generated one-time code sent to your email address or mobile phone, or even fingerprints and face recognition.
It makes access more complicated but also serves as an additional barrier to compromise attempts and data thieves. This motivates them to move on to more straightforward targets. While it isn't infallible, it does dissuade attackers from trying anything else, potentially rescuing you from disaster.
Another successful way of protection is the passphrase that is used instead of common password combinations. It is represented as the meaningful or meaningless word combination consisting of up to 100 words. It seems to be hard to remember a long phrase, but it is much easier than remembering alpha-numeric combinations including substitution, capitalization, and different numbers. Hackers will find it incredibly difficult to break into a system since passwords are several words long and can contain an endless number of word combinations. Another good thing about such protection is the lack of necessity to install the special apps or systems required to use this technique. It can be applied to every account without special password character limits.
Is the password dead?
The first hacking attacks were conducted as early as the 80s. Regardless of this, people still use passwords as the main protection force for their private information. So, why can’t we replace it with more modern and convenient technologies?
First of all, it’s related to the ease of creating passwords. The password is generated by the user himself, so there’s no need to create and exploit special services that would be able to provide protection for the account on the user’s behalf. Another point is the privacy of users. The password is one of the more private ways of authentication as it doesn’t require any personal information, it can be a random combination of numbers and lack sense, unlike methods such as biomedical data access, which is connected with personal information that could get out into cyberspace. The last but not the least important point lies in the simplicity of replacing passwords. It can be useful in the event of a major data breach, as it’s easier to change the password than the biomedical options that are used for fingerprints or face recognition.
Conclusion
So what will be the future of passwords? Passwords will definitely be used as one layer of a multi-factor security system for the next few years as there are still no more useful options for saving our privacy than passwords. People are continuing to look for the perfect method of protection, so maybe in a few years, something will finally appear and the world will be able to say goodbye to long sophisticated passwords. Some services have already turned to new systems of access, like one-time codes or fingerprints, but there is still a possibility of being hacked. Indeed, users still believe that a multi-layer system of protection is more convenient than any possible alternative.
Which words pop into your head when creating a password for your new account on a website or on a social network? Safety? Privacy? Well, there’s some bad news — hackers are clued-up on hacking any kind of password that you can think into existence, and as a matter of fact, it’s a global problem.
According to recent Kaspersky analysis of 193 million real-world passwords, 59% can be cracked in under one hour using a modern GPU and smart guessing algorithms. Even more alarming, 45% of those passwords fall in under one minute. This data underscores a harsh reality for enterprise security teams: traditional password complexity rules are failing.
Attackers no longer rely solely on manual guessing. They deploy industrialized, AI-assisted tools and Malware-as-a-Service platforms to harvest credentials at an unprecedented scale. The leak of 16 billion credentials from 30 data sources and the exposure of 184 million credentials on underground markets demonstrate the sheer volume of data available to threat actors.
This article explains how each major password cracking technique works, the real-world scale of these threats, and what organizations must do to defend against them. Understanding the attacker’s toolkit is the first step in securing your enterprise infrastructure.
What is password cracking?
Password cracking is the process by which attackers attempt to recover or bypass authentication credentials — either by decrypting stolen password hashes offline or by guessing credentials directly against live systems. Techniques range from automated brute-force and dictionary attacks to AI-powered guessing, phishing, and infostealer malware.
Security professionals divide these techniques into two primary categories: online and offline attacks:
Online attacks involve interacting directly with a live authentication system, such as a website login portal or an SSH gateway. These attacks are inherently constrained by network latency, rate-limiting, and account lockout policies.
Offline attacks pose a far greater enterprise threat. When attackers steal a database of hashed passwords, they can attempt to crack them on their own hardware without triggering any network alarms. Unconstrained by rate limits, attackers leverage immense computational power. A single modern GPU, such as an NVIDIA RTX 4090, can process 164 billion MD5 hashes per second. Against this level of hardware, weak passwords are mathematically trivial to break.
Top 12 Password cracking techniques hackers use in 2025
1. Brute force attack
A brute force attack relies on exhaustive enumeration. The attacker’s software systematically tries every possible combination of characters — letters, numbers, and symbols — until it finds the correct match. It is the most fundamental password cracking technique, guaranteeing success eventually, provided the attacker has enough time and computing power.
The scale of brute force attacks has expanded massively due to cloud computing. Attackers can rent massive GPU clusters for a few dollars per hour, bringing supercomputer-level cracking capabilities to anyone.
To defend against brute force attacks, organizations must enforce minimum length requirements of at least 12 characters. Length provides exponentially more protection than complexity. Implement strict account lockout policies for online portals to stop live guessing.
For stored data, ensure all passwords are hashed using computationally expensive algorithms like bcrypt or Argon2, which intentionally slow down the verification process and neutralize hardware advantages.
2. Dictionary attack
A dictionary attack uses a precompiled list of likely passwords to guess credentials. Attackers leverage massive wordlists, such as the infamous RockYou dataset, Have I Been Pwned dumps, and custom lists derived from Open-Source Intelligence (OSINT). They combine these base words with rule-based mutations, adding common numbers, capitalization, and “leet speak” substitutions (e.g., replacing “a” with “@”).
This method is highly efficient because we are predictable. We favor memorable words and patterns. Kaspersky’s analysis revealed that 57% of all analyzed passwords contain a dictionary word or a common symbol combination. Instead of trying every possible character, a dictionary attack tests the passwords people actually use, drastically reducing the time required to breach an account.
Defense requires blocking common passwords at the point of creation. Integrate a breached password monitoring service into your Active Directory or identity provider to prevent users from selecting known compromised terms. Enforce true randomness in password generation, moving away from simple substitutions that dictionary rules easily anticipate.
3. Credential stuffing
Credential stuffing exploits the human habit of password reuse. Attackers take massive lists of usernames and passwords exposed in one breach and systematically test them across hundreds of other services using automated botnets. If a user utilizes the same password for their personal email and their corporate VPN, a breach of the former immediately compromises the latter.
The 2025 Verizon Data Breach Investigations Report (DBIR) highlights the dominance of this technique. Compromised credentials served as the initial access vector in 22% of all confirmed breaches. Credential stuffing accounted for a median 19% of all daily authentication attempts across monitored networks, spiking to an overwhelming 44% on the worst days. The 2023 breach of 23andMe stands as a canonical example of how devastating this attack vector can be when users recycle credentials.
Defending against credential stuffing requires eliminating password reuse entirely. The only reliable way to prevent credential stuffing is to use unique, complex passwords for every corporate service.
Since employees cannot memorize dozens of unique credentials, companies must implement an enterprise password manager like Passwork. It automatically generates and securely stores unique credentials, eliminating the practice of password reuse. Deploy Multi-Factor Authentication (MFA) across all external-facing portals. Security teams must monitor authentication logs for anomalous login patterns.
4. Password spraying
Password spraying is the inverse of a traditional brute force attack. Instead of trying thousands of passwords against a single account, an attacker tries one highly probable password — such as "“Password1!” or “Welcome2025” — against thousands of different accounts. This “low and slow” approach is specifically designed to evade account lockout policies and intrusion detection systems.
This technique remains highly effective against large organizations. SSH.com notes that Single Sign-On (SSO) environments are particularly vulnerable, as one successful guess grants access to a wide array of corporate resources. Attackers often time their spraying campaigns to coincide with corporate events, seasonal changes, or new employee onboarding, using passwords relevant to the context.
To stop password spraying, organizations must block commonly sprayed passwords globally. Implement MFA to ensure that a guessed password alone is insufficient for access. Security Information and Event Management (SIEM) systems should be configured to monitor for distributed, low-frequency login failures across the network, which often indicate an ongoing spray attack.
5. Rainbow table attack
A rainbow table attack uses massive, precomputed tables of hash-to-plaintext pairings to reverse cryptographic hashes instantly. Instead of calculating hashes on the fly, the attacker simply looks up the stolen hash in their database to find the corresponding password. This technique is devastatingly effective against older, unsalted hashing algorithms like LM, NTLM, and MD5.
The effectiveness of rainbow tables relies entirely on the absence of a cryptographic “salt” — a random string of data added to the password before hashing. If two users have the same password, an unsalted hash will look identical for both. A rainbow table exploits this predictability. Defending against rainbow tables is straightforward: ensure all password storage uses salted hashing. When a unique salt is added to every password, the precomputed tables become useless.
6. Phishing and spear phishing
The easiest and most common way of hacking someone’s password is phishing. There are plenty of techniques here: phishing can take the form of an email, an SMS, a direct message on a social media platform, or a public post on a website.
Phishing bypasses the technical challenge of cracking a password by simply tricking the user into handing it over. Attackers deploy fake login pages, deceptive email lures, and sophisticated Adversary-in-the-Middle (AiTM) proxy attacks. AiTM attacks are particularly dangerous because they sit between the user and the legitimate service, capturing session cookies and MFA tokens in real time.
Adversary-in-the-Middle (AiTM) is a type of cyberattack where an attacker secretly intercepts and relays communication between a user and a legitimate service in real time.
Phishing takes many forms. Spear phishing targets specific individuals with highly personalized lures. Smishing uses SMS messages, vishing relies on voice calls, and whaling targets C-suite executives. The IBM Cost of a Data Breach Report 2025 identified phishing as the most common initial attack vector, responsible for 16% of breaches at an average cost of $4.88 million per incident.
Defense requires a multi-layered approach. Regular security awareness training helps employees recognize deceptive tactics. Deploy strict email filtering and DMARC authentication to block malicious messages before they reach the inbox. Most importantly, organizations must transition to phishing-resistant MFA, such as FIDO2 security keys or passkeys, which mathematically bind the authentication token to the specific legitimate domain, rendering stolen credentials useless.
When an employee navigates to a login page, the Passwork browser extension analyzes the underlying URL before offering to autofill any credentials. If an attacker uses a deceptive domain — such as “micros0ft.com” instead of “microsoft.com” — that visually impersonates a legitimate corporate service, Passwork will not recognize the site and will refuse to insert the password.
7. Keylogger and infostealer malware
While traditional keyloggers simply recorded keystrokes, modern attackers utilize highly sophisticated infostealer malware. Families like Lumma, Acreed, and StealC V2 operate silently, extracting saved browser passwords, active session cookies, cryptocurrency wallets, and MFA tokens in a single sweep.
The scale of this threat is staggering. According to Vectra AI and DeepStrike, infostealers stole 1.8 billion credentials from 5.8 million devices in 2025 — representing an 800% year-over-year increase. This explosion is driven by the Malware-as-a-Service (MaaS) model. Sophisticated infostealer platforms are available on dark web forums for as little as $200 per month, lowering the barrier to entry for cybercriminals.
To defend against infostealers, organizations must deploy robust Endpoint Detection and Response (EDR) solutions. Implement privileged access management to restrict the execution of unauthorized software. Employees must be strictly prohibited from saving corporate credentials in built-in browser password managers. Using a dedicated, encrypted vault like Passwork isolates credentials from malicious endpoint processes and prevents mass theft by infostealers.
8. Man-in-the-Middle (MitM) attack
A Man-in-the-Middle (MitM) attack occurs when an attacker intercepts communication between a user and a legitimate service. This can happen on unsecured public Wi-Fi networks, through rogue access points, or via DNS cache poisoning. The attacker captures the traffic, extracting plaintext passwords or session tokens as they travel across the network.
The modern evolution of this technique is the Adversary-in-the-Middle (AiTM) proxy attack. Attackers use reverse proxies to seamlessly relay traffic between the victim and the real authentication server. When the user enters their password and MFA code, the proxy captures the resulting authenticated session cookie, allowing the attacker to bypass MFA entirely.
Defense relies on robust encryption and network security. Enforce HTTPS and TLS 1.3 across all internal and external communications. Require the use of corporate VPNs when employees connect from public or untrusted networks. To defeat AiTM attacks, deploy phishing-resistant FIDO2 authentication, which validates the origin of the request and prevents session token theft.
9. Social engineering
Social engineering attacks target the human layer of security. Attackers use pretexting, impersonation, and psychological manipulation to bypass technical controls. A common tactic involves calling the IT service desk, impersonating a legitimate employee, and requesting an urgent password reset.
Research from Specops Secure Service Desk highlights that helpdesk agents are frequent targets for these attacks. Attackers gather personal information from LinkedIn or other public sources to answer basic security questions, convincing the agent to hand over temporary credentials or reset an MFA device.
Defending against social engineering requires strict, verifiable protocols. Service desks must implement rigorous identity verification procedures that do not rely on easily discoverable public information. Security awareness training should extend to IT staff, focusing on the tactics used to manipulate support personnel. Implement Zero Trust access policies to limit the blast radius if an account is compromised through human error.
10. Hybrid attack
A hybrid attack combines the speed of a dictionary attack with the thoroughness of a brute force approach. Attackers take a known base word — often a company name, a season, or a previously leaked password — and append or prepend numbers, symbols, and years.
This technique is exceptionally effective against post-breach password resets. When forced to change a compromised password like “Atlanta2024!”, a user will predictably change it to “Atlanta2025!”. Attackers know this behavior and configure their cracking tools to test these incremental variations automatically.
Defense requires strict password history policies. Active Directory and identity providers must be configured to block incremental variations of previous passwords. Organizations should move away from arbitrary password expiration policies, which encourage users to create predictable, iterative passwords, and instead focus on continuous breached password monitoring.
11. Pass-the-Hash (PtH) and Kerberoasting
Pass-the-Hash (PtH) and Kerberoasting are advanced techniques specifically targeting enterprise Active Directory environments. In a PtH attack, an adversary extracts the NTLM hash of a user’s password from a compromised machine’s memory using tools like Mimikatz. They then use this hash to authenticate to other network resources without ever needing to crack the plaintext password.
Kerberoasting targets service accounts. Any authenticated domain user can request a Kerberos service ticket for a Service Principal Name (SPN). The attacker extracts this ticket and takes it offline, attempting to crack the service account’s password hash at their leisure. Because service accounts often have high privileges and rarely change their passwords, they are prime targets.
Defending against these lateral movement techniques requires strict control over privileged accounts. Adhere to the principle of least privilege. Passwork allows teams to securely manage shared administrative passwords using a Role-Based Access Control (RBAC) model, ensuring that critical hashes are not compromised due to careless storage. Monitor network traffic for unusual Kerberos ticket requests. Transition to Group Managed Service Accounts (gMSAs), which automatically rotate complex passwords, eliminating the risk of offline Kerberoasting.
12. AI-powered password guessing
Artificial Intelligence has fundamentally altered the password cracking landscape. Tools like PassGAN use Generative Adversarial Networks (GANs) trained on massive datasets of leaked credentials. Instead of relying on static wordlists or rigid mutation rules, these neural networks learn the underlying psychology of how humans construct passwords. They generate statistically likely candidates with terrifying accuracy.
When AI generation is combined with high-speed hashing tools like Hashcat, the overall success rate of cracking campaigns increases dramatically. AI tools complement traditional methods, filling the gaps where dictionary rules fail.
Defense against AI-powered guessing requires passwords that lack human patterns entirely. Organizations must mandate the use of password managers to generate and store passwords of 15 or more characters with true cryptographic randomness. Combine this with robust MFA and continuous breached password monitoring to mitigate the threat of AI-generated guesses.
How hackers prioritize their targets
Attackers operate with a clear economic model, prioritizing techniques based on efficiency, scale, and the value of the target. Credential stuffing and phishing are the preferred methods for mass exploitation. Because stolen credentials sell for as little as $10 on criminal markets, the return on investment for automated stuffing campaigns is exceptionally high.
When attackers acquire a database of hashed passwords, they turn to dictionary attacks and AI-powered guessing, reserving resource-intensive brute force attacks for high-value administrative accounts. Infostealer malware is deployed selectively against targets likely to yield access to corporate networks, cryptocurrency assets, or proprietary source code.
Time is always on the attacker’s side. Check Point found that organizations take an average of 94 days to remediate compromised credentials exposed in GitHub repositories. Attackers exploit this window aggressively, using automated scripts to validate and weaponize leaked secrets within minutes of exposure. Understanding this prioritization helps defenders allocate their resources effectively, focusing on the attack vectors that present the highest statistical risk.
How to protect your organization against password cracking
Securing an enterprise against modern password cracking requires a comprehensive, layered defense strategy. Technical controls must align with human behavior to create a resilient authentication environment.
Enforce strong, unique passwords Length matters more than complexity. Following NIST SP 800-63B guidance, organizations should require passwords of at least 12 characters. Because humans cannot memorize dozens of long, random strings, provide an enterprise password manager to generate and store truly random credentials for every service.
Deploy Multi-Factor Authentication (MFA) MFA is mandatory, but not all MFA is equal. Prioritize phishing-resistant authentication methods like FIDO2 security keys or passkeys. Move away from SMS-based One-Time Passwords (OTPs), which are highly vulnerable to SIM swapping and AiTM proxy attacks.
Monitor for breached credentials The Verizon 2025 DBIR notes that only 3% of passwords meet NIST complexity requirements. Organizations must continuously check employee passwords against known breach databases. If a credential appears in a public dump, the system should force an immediate reset.
Implement privileged access management Protect service accounts and shared credentials, which are the primary targets for lateral movement attacks like Pass-the-Hash and Kerberoasting. Restrict administrative access and log all privileged sessions.
Conduct security awareness training Social engineering and phishing remain the most common initial access vectors. Regular, contextual training and simulated phishing tests measurably reduce employee susceptibility to credential harvesting lures.
Deploy a centralized enterprise password manager Security policies work effectively when employees have convenient tools to follow them. Implementing an enterprise password manager like Passwork solves the human factor problem.
Passwork provides teams with an encrypted vault featuring granular Role-Based Access Control (RBAC), detailed audit logs, and seamless Active Directory/SSO integration. For companies with strict compliance requirements, Passwork offers an on-premise version, allowing organizations to host all encrypted data exclusively on their own servers and eliminate the risks associated with cloud breaches.
Conclusion
The threat landscape has shifted fundamentally. Password cracking has evolved from a niche technical skill into an industrialized, AI-assisted, and MaaS-enabled attack category. The 2025 data is unambiguous: stolen credentials drive the vast majority of corporate breaches, and the tools available to attackers have never been more powerful or accessible. Relying on outdated complexity rules and manual password management is a guaranteed path to compromise.
The most effective organizational response requires a holistic approach. It combines strong password hygiene, phishing-resistant MFA, continuous breach monitoring, and a centralized password management platform.

Frequently asked questions
What is the most common password cracking technique in 2025?
Credential stuffing is the most prevalent technique at scale, accounting for a median 19% of all daily authentication attempts according to the Verizon 2025 DBIR. Phishing was the most common initial breach vector, responsible for 16% of confirmed breaches, as reported in the IBM 2025 Cost of a Data Breach Report.
How long does it take to crack a password?
It depends entirely on length, complexity, and the hashing algorithm used. Kaspersky’s analysis of 193 million real-world passwords found that 59% could be cracked in under one hour using a modern GPU and smart guessing algorithms. An 8-character alphanumeric password can be cracked by an RTX 4090 in approximately 17 seconds. Passwords of 15 or more truly random characters would take centuries to crack with current hardware.
To guarantee the use of such cryptographically strong passwords without sacrificing productivity, organizations should rely on built-in password generators provided by solutions like Passwork.
What is the difference between a brute force and a dictionary attack?
A brute force attack tries every possible character combination systematically, which is thorough but slow. A dictionary attack uses a precompiled list of likely passwords, including common words, leaked credentials, and OSINT-derived terms. Dictionary attacks are far faster in practice because most real-world passwords follow predictable human patterns.
Can AI crack passwords?
Yes. AI-powered tools like PassGAN use neural networks trained on real password datasets to generate statistically likely guesses. Research shows PassGAN can crack 51% of common passwords in under one minute and 65% within one hour — significantly outperforming traditional dictionary attacks on their own.
Does multi-factor authentication prevent password cracking?
MFA significantly raises the bar, but it is not a complete defense. Adversary-in-the-Middle (AiTM) attacks can intercept MFA tokens in real time. Phishing-resistant FIDO2 or passkey authentication is the current gold standard for preventing credential-based attacks.
Cryptography is both beautiful and terrifying. Perhaps a bit like your ex-wife. Despite this, it represents a vital component of day-to-day internet security; without it, our secrets kept in the digital world would be exposed to everyone, even your employer. I doubt you’d want information regarding your sexual preferences to be displayed to the regional sales manager while at an interview with Goldman Sachs, right?
Computers are designed to do exactly what we ask them to do. But sometimes there are certain things that we don’t want them to do, like expose your data through some kind of backdoor. This is where cryptography comes into play. It transforms useful data into something that can’t be understood without the proper credentials.
Let’s take a look at an example. Most internet services need to store their users’ password data on their own servers. But they can’t store the exact values that people input on their devices because, in the event of a data breach, malevolent intruders would effectively gain access to a simple spreadsheet of all usernames and passwords.
This is where ‘Hash’ and ‘Salt’ help us a lot. Throughout this article, we’re going to explain these two important encryption concepts through simple functions in Node.JS.
What is a ‘hash’?
A ‘hash’ literally means something that has been chopped and mixed, and originally was used to describe a kind of food. Now, chopping and mixing are exactly what the hash function does! You start with some data, you pass it through a hash function where it gets whisked and chopped, and then you watch it get transformed into a fixed-length value (which at first sight seems pretty meaningless). The important nuance here is that, contrary to cooking, an input always produces a corresponding output. For the purposes of cryptography, such a hash function should be easily computable and all values should be unique. It should work in a similar way to mashing potatoes – mashing is a one-way process; the raw potato may not be restored once it has been mashed. Indeed, the result of a hash function should be impenetrable to computer-led reverse engineering efforts.
These properties come in handy when you’re looking to store user passwords on a database – you don’t want anyone to know their real values.
First, let’s import the createHash function from the built-in ‘crypto’ module:
const { createHash } = require ('crypto');
Next, we ought to define the module that we’re naming as the ‘hash’ (which takes a string as the input, and returns a hash as the output):
function hash(input) {
return createHash();
}
We also need to specify the hashing algorithm that we want to use. In our case, it will be SHA256. SHA stands for Secure Hash Algorithm and it returns a 256-bit digest (output). It is important to architect your code so it is easy to switch between algorithms because at some point in time they won’t be secure anymore. Remember, cryptography is always evolving.
function hash(input) {
return createHash('sha256');
}
Once we call our hashing function, we may call ‘update’ with the input value and return the output by calling ‘digest’. We should also specify the format of the output (e.g. hex). In our case, we’ll go with Base64.
function hash(input) {
return createHash('sha256').update(input).digest('base64');
}
Now that we have our hash function, we can provide some input, and console log the result.
let youShallNotPassPass = 'admin1234';
const hashRes1 = hash(youShallNotPassPass);
console.log(hashRes1)
So, how can we use this long, convoluted string of numbers, letters, and symbols? Well, now it’s easy to compare two values while operating with only hashes.
let youShallNotPassPass = 'admin1234';
const hashRes1 = hash(youShallNotPassPass);
const hashRes2 = hash(youShallNotPassPass);
const isThereMatch = hashRes1 === hashRes2;
console.log(isThereMatch ? 'hashes match' : 'hashes do not match’)
As long as hash values are unique object representations, they can be useful for object identification. For example, they might be used to iterate through objects in an array or find a specific one in the database.
But we have a problem. Hash functions are very predictable. On top of that, people don’t use strong passwords that often, so the hacker may just compare the hashes on a database with a precomputed spreadsheet of the most common passwords. If the values match – the password is compromised.
Because of this, it’s insufficient to just use a hash function to store unique ids on a password database.
And that’s where our second topic makes an entrance – Salt.
‘Salt’ is a bit like the mineral salt that you would add to a batch of mashed potatoes – the taste will definitely depend on the amount and type of salt used. This is exactly what salt in cryptography is – random data that is used as an additional input to a hash function. Its use makes it much harder to guess what exact data stands behind a certain hash.
We use ‘Scrypt’ because it’s designed to be expensive computationally and memory-wise in order to make brute-force attacks unrewarding. It’s also used as proof of work in cryptocurrency mining.
Now that we have hashed the password, we need to store the accompanying salt in our database. We can do this by appending it to the hashed password with a semicolon as a separator:
const user = { nickname, password: salt + ':' + hashedPassword}
Here’s our final signup function:
function signup(nickname, password) {
const salt = randomBytes(16).toString('base64');
const hashedPassword = scryptSync(password, salt, 64).toString('base64');
const user = { nickname, password: salt + ':' + hashedPassword};
users.push(user);
return user;
}
Now let’s create our login function. When the user wants to log in, we can grab the salt from our database to recreate the original hash:
//We register the user:
const user = signup('Amy', '1234');
//We try to login with the wrong pass:
let isSuccess = login('Amy', '12345');
console.log(isSuccess ? 'Login success' : 'Wrong password!')
//Wrong password!
//We try to login with the correct pass:
isSuccess = login('Amy', '1234')
console.log(isSuccess ? 'Login success' : 'Wrong password!')
//Login success
Our example, hopefully, has provided you with a very simplified explanation of the signup and login process. It’s important to note that our code is not protected against timing attacks and it doesn’t use PKI infrastructure to check hashes, so there are plenty of vulnerabilities for hackers to exploit.
Cryptography itself can be described as the constant war between hackers and cryptographic engineers. Or, that familiar legal battle with your ex-wife over her maintenance payments. After all, what works today may not work tomorrow. A proof of MD5 hash algorithm vulnerability is a very good example.
So if your task is to ensure your users’ data privacy, be ready to constantly update your functions to counteract the recent ‘breakthroughs’.
