Facepalm: A couple of years ago, Kaspersky Lab tested the resilience of hashed passwords against a modern gaming GPU. Now, the Moscow-based security firm has updated its study and found that things are getting slightly – but undeniably – worse.

Just in time for World Password Day, Kaspersky is reminding everyone that outdated hashing algorithms such as MD5 remain among the worst choices for storing passwords. In a recent post, the security firm revisited a 2024 study examining the "crackability" of real-world passwords. The conclusion is not surprising: password cracking speeds continue to improve, which means overall security is steadily getting worse.

Hashing algorithms are designed to convert strings of arbitrary length into fixed-length hash values. Even the smallest change in the input text produces a completely different hash, meaning that a...
