Kaspersky is a very secure password manager. It provides military-grade 256-bit AES encryption, has a zero-knowledge policy, comes with 2FA, and offers some extras like a password strength checker that can increase your password security further.
While this tools identifies many of the most common passwords, it cannot account for for all passwords and the wide range of tools hackers can use to crack them. Using predictable sequences of characters or other non-random sequences will make a password significantly more easy to break and not every such sequence will be picked up by this tool. It is designed for educational purposes only and we cannot guarantee its accuracy.
As an example, advanced password crackers can predict punctuation and capitalization patterns that are not tested for here. Avoid using predictable alterations of dictionary words, for instance, substituting 4 for A or $ for S. These patterns are reflected in the increasingly sophisticated rulesets, dictionaries, and combinations used by modern hackers, as well as the growing number of leaked and cracked password lists.
Strong and varied passwords are the best defense against hackers and other unauthorized users attempting to gain access to your online accounts. Hackers can use sophisticated tools to guess at probable combinations of characters to crack a password.
In the past, where "brute forcing" a password simply meant attempting every possible combination of letters and numbers until the software happened upon the correct sequence. That took a lot of time and computing power, making it worthwhile for hackers to only crack the simplest and shortest passwords.
Nowadays, however, password cracking software is much more advanced. It significantly narrows down possible alphanumeric combinations by analyzing and inputting common patterns, saving hackers time and resources. Advanced password crackers can predict punctuation and capitalization patterns based on always-improving rulesets, dictionaries, and the growing number of leaked and cracked password lists.
"Kaspersky Password Manager used a complex method to generate its passwords. This method aimed to create passwords hard to break for standard password crackers. However, such method lowers the strength of the generated passwords against dedicated tools," Bédrune wrote.
"Their password cracking method relies on the fact that there are probably 'e' and 'a' in a password created by a human than 'x' or 'j', or that the bigrams 'th' and 'he' will appear much more often than 'qx' or 'zr'," he said.
"Passwords generated by KPM will be, on average, far in the list of candidate passwords tested by these tools. If an attacker tries to crack a list of passwords generated by KPM, he will probably wait quite a long time until the first one is found. This is quite clever."
To understand the basics of how long a password would take to crack vs. its amount of entropy, there is a very simplified formula to follow. Please note that this is a very, very simplified explanation but here it goes.
Keep in mind that while these passwords are stored on a web server, they are usually protected by a maximum number of password attempts over a certain amount of time. But, if the website ever gets hacked then its password hashes can be easily run through any offline cracking system that the hackers have set up.
35.5 bits of entropy = 398 days for the average Joe to crack, but only 0.5 seconds for a supercomputer to break. That translates to less than a minute for almost any cracking expert out there to break in!
107.4 bits of entropy = 5,141,800,300,000,000,000 millennia for the average Joe password cracker to break. On a supercomputer, it would take 81,615,877,245 millennia to crack. It is highly unlikely it will ever be cracked unless your password is singled out and targeted by multiple systems.
Hence, passwords generated by KPM will be, on average, far in the list of candidate passwords tested by these tools. If an attacker tries to crack a list of passwords generated by KPM, he will probably wait quite a long time until the first one is found. This is quite clever.
However, if an attacker knows that a password has been generated by KPM, he can adapt his tool to take into account the model followed by KPM. As these passwords are, in a certain sense, biased (to tackle password crackers), this bias can be used to generate the most probable passwords generated by this tool, and test them first. A straightforward way to do it could be to use a Markov generator, as the one provided by John the Ripper (This method has not been tested).
The advantage of this tool is that it not only gives you key stats about the password you input (how long is it? what kind of characters are you using? how long would it take to crack the password?), it also provides feedback.
Nordpass evaluates each password by checking for a few basic elements: length (at least 12 characters), lowercase and uppercase letters, symbols, and numbers. It also estimates how long it would take to crack the password and determines whether it has been compromised in previous data breaches.
This application is designed to assess the strength of password strings. The instantaneous visual feedback provides the user a means to improve the strength of their passwords, with a hard focus on breaking the typical bad habits of faulty password formulation. Since no official weighting system exists, we created our own formulas to assess the overall strength of a given password. Please note, that this application does not utilize the typical "days-to-crack" approach for strength determination. We have found that particular system to be severely lacking and unreliable for real-world scenarios. This application is neither perfect nor foolproof, and should only be utilized as a loose guide in determining methods for improving the password creation process.
These attacks are simple because many people still use weak passwords, such as "password123" or "1234," or practice poor password etiquette, such as using the same password for multiple websites. Passwords can also be guessed by hackers that do minimal reconnaissance work to crack an individual's potential password, such as the name of their favorite sports team.
Brute force attack tools include password-cracking applications, which crack username and password combinations that would be extremely difficult for a person to crack on their own. Commonly used brute force attack tools include:
The best way to defend against brute force attacks that target passwords is to make passwords as tough as possible to crack. End-users have a key role to play in protecting their and their organization's data by using stronger passwords and following strict password best practices. This will make it more difficult and time-consuming for attackers to guess their passwords, which could lead to them giving up.
A 128-bit encryption key would require two to the power of 128 combinations to crack, which is impossible for most powerful computers. Most websites and web browsers use it. 256-bit encryption makes data protection even stronger, to the point that even a powerful computer that can check trillions of combinations every second would never crack it. This makes 256-bit encryption completely immune to brute force attacks.
The longer and more complex a password is, the more difficult it is to crack. An eight-character password is widely considered to be crackable in a few hours. A 2019 research found that any eight-character password, no matter how complex, could be cracked in just 2.5 hours.
In December 2018, a new ransomware called Djvu, which could be a variant of STOP, was released that has been heavily promoted through crack downloads and adware bundles. Originally, this ransomware would append a variation of the .djvu string as an extension to encrypted files, but a recent variant has switched to the .tro extension.
When first released, it was not known how the ransomware was being distributed and a sample of the main installer could not be found. When discussing the infection with the numerous victims who reported it in our forums and elsewhere, a common theme was noted; most of the victims stated that they became infected after downloading a software crack.
Certain cracks and adware bundles are installing this ransomware onto victim's computers. When these cracks are installed, the main installer will be installed as %LocalAppData%\[guid]\[random].exe and executed. This program is the main ransomware component and will first download the following files to the same folder:
Getting creative with passwords only solves a small part of the problem. Kaspersky's handy Password Checker tool demonstrates how quickly it takes for a password to be cracked using brute-force methods.
A password of 'password' takes less than a second to crack, while something like 'correcthorsebatterystaple' from XKCD's webcomic on password strength would take 892,000 years before it's compromised via brute-force.
These options - be it password checkers or email address checkers - are only some of many ways to manage your cybersecurity via your fingertips. Alternatives include using a password manager or limiting the number of online accounts to the bare essentials.
