Unfortunately, according to security researcher Jean-Baptiste Bédrune, a bad coding decision meant that the passwords it generated weren't truly random and as a result were relatively easy to brute force - a hacking technique using specialized tools to try hundreds of thousands (or millions) of password combinations in an attempt to guess the right one.īédrune, who is a security researcher for the cryptocurrency hard-wallet company Ledger, writes that when generating a supposedly random password, KPM used the current time as its "single source of entropy."

The Kaspersky Password Manager (KPM), a free tool used to generate and manage online passwords, has long been a popular alternative to the likes of LastPass or 1Password. To make the process of receiving updates easier, our home products support automatic updates.Password managers are a vital line of defense in the battle for internet security - which makes it all the more painful when they shit the bed.

We recommend that our users install the latest updates. “The company has issued a fix to the product and has incorporated a mechanism that notifies users if a specific password generated by the tool could be vulnerable and needs changing. It would also require the target to lower their password complexity settings. “This issue was only possible in the unlikely event that the attacker knew the user’s account information and the exact time a password had been generated. “Kaspersky has fixed a security issue in Kaspersky Password Manager, which potentially allowed an attacker to find out passwords generated by the tool,” a Kaspersky spokesperson told IT Pro. This means that if every user generated a password at the same time, they would see the same generated password.īédrune suggests the result is that every password could be brute-forced, especially if hackers know the creation date of an account.

The only source of entropy the password generator used, too, was time, and there was a one-second animation between generated passwords. Our recommendation is, however, to generate random passwords long enough to be too strong to be broken by a tool.” “However, if an attacker knows a person uses KPM, he will be able to break his password much more easily than a fully random password. “We can conclude that the generation algorithm in itself is not that bad: it will resist against standard tools,” Bédrune said. As they’re biased to some extent, this can be abused to generate the most probable passwords generated by this tool. If, however, an attacker knows the password has been generated by KPM, they can adapt their tool around the model KPM uses to generate the password. Passwords generated by KPM will be far in the list of candidate passwords tested by standard cracking tools, so attackers will likely be waiting a long time before they encounter a KPM password when attempting to crack a list of passwords. The method has been implemented to trick standard password cracking tools, according to Ledger Donjon researcher Jean-Baptiste Bédrune, which try first break probable passwords, such as those generated by humans.

Once any given letter is generated, it heavily skews the probability of other letters appearing in the same password.

The generation process is a complex method but effectively means that letters such as q, z and x are more likely to appear in passwords generated by KPM than the average password manager. By default, KPM generates 12-character passwords with an extended chart set.

The built-in password generator creates passwords from a given policy, with users able to set policy settings to change password length and include uppercase letters, lowercase letters, digits and a custom set of special characters.

The issue has now been patched, but several versions of KPM are affected including version 9.0.2 Patch F and earlier on Windows, version 9.1.14.872 and earlier on Android, and version 9.2.14.31 and earlier on iOS. Kaspersky has assigned this vulnerability the tag CVE-2020-27020, and has published a security advisory regarding this flaw.
