My guess about the former is that Password Safe isn’t as popular as the others. Several people have emailed me to ask why my own Password Safe was not included in the evaluation, and whether it has the same vulnerabilities. Whether this is a big deal or not depends on whether you consider your computer to be trusted. In the case of Windows APIs, sometimes, various memory buffers which contain decrypted entries may not be scrubbed correctly. However, errors in workflows permitted the researchers from extracting credential entries which have been interacted with. KeePass scrubs the master password from memory and is not recoverable. It was also possible for the researchers to extract the master password and interacted-with password entries due to a memory leak.

However, ISE reported that these entries persist in memory after the software enters a locked state.

LastPass obfuscates the master password while users are typing in the entry, and when the password manager enters an unlocked state, database entries are only decrypted into memory when there is user interaction. However, each password manager fails in implementing proper secrets sanitization for various reasons. It is evident that attempts are made to scrub and sensitive memory in all password managers. This paper is not meant to criticize specific password manager implementations however, it is to establish a reasonable minimum baseline which all password managers should comply with. If 1Password4 scrubbed the master password memory region upon successful unlocking, it would comply with all proposed security guarantees we outlined earlier. This is in contrast to 1Password4, where at most, a single entry is exposed in a “running unlocked” state and the master password exists in memory in an obfuscated form, but is easily recoverable. This was most evident in 1Password7 where secrets, including the master password and its associated secret key, were present in both a locked and unlocked state. But residual buffers remained that contained secrets, most likely due to memory leaks, lost memory references, or complex GUI frameworks which do not expose internal memory management mechanisms to sanitize secrets. That is, if a password database were to be extracted from disk and if a strong master password was used, then brute forcing of a password manager would be computationally prohibitive.Įach password manager also attempted to scrub secrets from memory. That is, does the password manager accidentally leave plaintext copies of the password lying around memory?Īll password managers we examined sufficiently secured user secrets while in a “not running” state. This work specifically looks at password leakage on the host computer. There’s new research on the security of password managers, specifically 1Password, Dashlane, KeePass, and Lastpass. I also recommend my own password manager: Password Safe.ĮDITED TO ADD: Commentary from Matthew Green.

More generally: generating random numbers is hard.

Stupid programming mistake, or intentional backdoor? We don’t know. The product has been updated and its newest versions aren’t affected by this issue. It also provides a proof of concept to test if your version is vulnerable.

This article explains how to securely generate passwords, why Kaspersky Password Manager failed, and how to exploit this flaw. 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. Vulnerability in the Kaspersky Password ManagerĪ vulnerability (just patched) in the random number generator used in the Kaspersky Password Manager resulted in easily guessable passwords:
