The psuedo random number generator (PRNG) being used to generate passwords for the Kaspersky Password Manager was very weak, and wasn’t not suitable for crytographic use. It was being seeded by the current time (in seconds), which meant that every instance of the Kaspersky Password Manager in the world would generate the exact same password at a given second. it was therefore very easy to bruteforce. It has subsequently been updated.
SamuraiSafe uses a cryptographically strong random number generator for generating passwords.
