KASPERSKY PASSWORD MANAGER THAT EASILY BRUTEFORCED GENERATORThis would be obvious to spot if every click on the ‘Generate' button, in the password generator interface, produced the same password.” It means every instance of Kaspersky Password Manager in the world will generate the exact same password at a given second. “So the seed used to generate every password is the current system time, in seconds. Here's how Ledger Donjon, head of security research at Jean-Baptiste Bédrune, explained it in a blog post: Yes, time, one of the most predictable and non-random metrics out there. But the seed that Kaspersky was starting with was the current current system time, in seconds. The issue was assigned CVE-2020-27020 and Kaspersky published an advisory in April, 2021.So what's the problem? Well, any random number generator needs one or more sources of entropy - the element of uncertainty that ensures the result remains random. KASPERSKY PASSWORD MANAGER THAT EASILY BRUTEFORCED PATCHAnd in October 2020, Kaspersky released KPM 9.0.2 Patch M, which included a notification to users that certain weak passwords need to be regenerated. With WPA3, Wi-Fi will be secure this time, really, wireless bods promiseĪ series of fixes – because the initial Windows patch didn't work properly – were rolled out to the web, Windows, Android, and iOS between October and December 2019.Pull your Western Digital My Book Live NAS off the internet now if you value your files.Dear Planet Earth: Patch Webmin now – zero-day exploit emerges for potential hijack hole in server control panel.Titan-ic disaster: Bluetooth blunder sinks Google's 2FA keys, free replacements offered."For example, there are 315619200 seconds between 20, so KPM could generate at most 315619200 passwords for a given charset. "The consequences are obviously bad: every password could be bruteforced," the Donjon team wrote. And if the creation time of an account is known – something commonly displayed in online forums, according to Donjon – that range of possibilities becomes much smaller and reduces the time required for bruteforce attacks to a matter of seconds. Nonetheless, the lack of randomness meant that for any given password character set, the possible passwords created over time are limited enough they can be brute-forced in a few minutes. All the passwords it created could be bruteforced in seconds." Its single source of entropy was the current time. "The most critical one is that it used a PRNG not suited for cryptographic purposes. "The password generator included in Kaspersky Password Manager had several problems," the Donjon research team explained in a blog post on Tuesday. In the sense that I’ve never seen so many broken things in one simple piece of code. I was going to laugh off this Kaspersky password manager bug, but it is *amazing*. KASPERSKY PASSWORD MANAGER THAT EASILY BRUTEFORCED SOFTWAREThree months later, a team from security consultancy Donjon found that KPM didn't manage either task particularly well – the software used a pseudo-random number generator (PRNG) that was insufficiently random to create strong passwords.įrom that time until the last few months of 2020, KPM was suggesting passwords that could be easily cracked, without flagging the weak passwords for users. KASPERSKY PASSWORD MANAGER THAT EASILY BRUTEFORCED UPDATEIn March 2019, security biz Kaspersky Lab shipped an update to KPM, promising that the application could identify weak passwords and generate strong replacements. Last year, Kaspersky Password Manager (KPM) users got an alert telling them to update their weaker passwords.
