The issue with the application, Ledger security researcher Jean-Baptiste Bédrune discovered roughly two years ago, was that its secure password generation mechanism was weak, allowing for created passwords to be brute-forced within seconds. KPM was designed to generate 12-character passwords by default, but allows users to personalize their passwords by modifying settings in the KPM interface, such as password length, and the use of uppercase and lowercase letters, digits, and special characters. The problem with KPM, Ledger’s researcher explains, is also what differentiated it from other password managers out there: in an attempt to create passwords that are as far away as possible from those generated by humans, the application became predictable. The passwords appeared to have been created so as to prevent cracking from commonly used password crackers. The employed algorithm, however, allowed an attacker who knew that the passwords were generated using KPM to create the most probable passwords generated by the utility, Bédrune says. “We can conclude that the generation algorithm in itself is not that bad: it will resist against standard tools. 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,” the researcher says.

Tracked as CVE-2020-27020, the vulnerability is related to the use of a pseudorandom number generator (PRNG) that was not cryptographically secure. #Kaspersky password manager flaw bruteforced passwords android#.#Kaspersky password manager flaw bruteforced passwords generator#.We make no guarantee that the passwords this tool generates will never be cracked. We remind users that hackers can get lucky and guess even the strongest of passwords. Users can also check the box to remove ambiguous characters, which in certain fonts may look alike.

Be wary of setting this too high, however, as a password that contains too many numbers will actually make it weaker. The user may set the minimum number of numeric characters that should be present in the password. For passwords under 12 characters, the strength score will be lower, and two passwords of the same length can have different strength scores. The 100% strength check is not enforced if the sum of the minimum number of symbols and the minimum number of digits equals the configured password length. If the check does not return a score of 100, the password is regenerated and checked again until a strength score of 100% is reached. This process is repeated for symbols.įor passwords of at least 12 characters: Once the password string is obtained, a strength check is performed. If too few numbers or symbols are present in the password variant, the Math.random method is used again to pick a numeric character to replace a non-numeric character in the password, and then the password characters are shuffled again using an algorithm based on Math.random. Choosing characters is done via the Math.random() Javascript method.

We do not store anything and no data is transmitted over the internet.Īll of the code used to build the password creator is our own, and the password checker is based on open-source code. Our password creator is implemented entirely in client-side Javascript, and the whole password generation process takes place on your browser.
