"In October 2020, users were notified that some passwords would need to be generated, with Kaspersky publishing its security advisory on 27 April 2021." "All public versions of Kaspersky Password Manager liable to this issue now have a new logic of password generation and a passwords update alert for cases when a generated password is probably not strong enough," the security company said.Read more of this story at Slashdot. "Kaspersky was informed of the vulnerability in June 2019, and released the fix version in October that same year," adds ZDNet. Bedrune added due to sites often showing account creation time, that would leave KPM users vulnerable to a bruteforce attack of around 100 possible passwords. "The consequences are obviously bad: every password could be bruteforced," he said. Because the program has an animation that takes longer than a second when a password is created, Bedrune said it could be why this issue was not discovered. They combine security with convenience by storing all your credentials in one place, allowing you to use strong, complex passwords that you don’t have to remember. "It means every instance of Kaspersky Password Manager in the world will generate the exact same password at a given second," Bedrune said. Our recommendation is, however, to generate random passwords long enough to be too strong to be broken by a tool." The big mistake made by KPM though was using the current system time in seconds as the seed into a Mersenne Twister pseudorandom number generator. "If an attacker knows a person uses KPM, he will be able to break his password much more easily than a fully random password. Stuxnet is a malicious computer worm first uncovered in 2010 and thought to have been in development since at least 2005. This is quite clever." The flip side was that if an attacker could deduce that KPM was used, then the bias in the password generator started to work against it. 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. "Passwords generated by KPM will be, on average, far in the list of candidate passwords tested by these tools. "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. One of the techniques used by KPM was to make letters that are not often used appear more frequently, which Bedrune said was probably an attempt to trick password cracking tools. Security researchers have discovered the random password generator of the Kaspersky Password Manager (KPM) was generating passwords that were susceptible to brute force attacks. However, such method lowers the strength of the generated passwords against dedicated tools," Bedrune wrote. Flaw in Kaspersky Password Manager Password Generator Made Passwords Susceptible to Brute Force Attacks. This method aimed to create passwords hard to break for standard password crackers. "Kaspersky Password Manager used a complex method to generate its passwords. In a blog post to cap off an almost two year saga, Ledger Donjon head of security research Jean-Baptiste Bedrune showed KPM was doing just that. Support may request logs, traces & other data they will guide you.An anonymous reader quotes a report from ZDNet: Suppose you are in the business of generating passwords, it would probably be a good idea to use an additional source of entropy other than the current time, but for a long time, that's all Kaspersky Password Manager (KPM) used.
