MD5

Researchers at Kaspersky found that 60% of MD5 password hashes can be cracked in under an hour using a single GPU, highlighting the vulnerability of passwords protected by fast hashing algorithms. This is due to password predictability and the increasing power of graphics processors. The study analyzed over 231 million unique passwords and found that passwords are actually easier to crack in 2026 than they were a couple of years ago.

The 2010 Flame malware attack exploited vulnerabilities in the MD5 cryptographic hash function to forge digital certificates, allowing malicious updates to be distributed to Iranian government networks. This event highlights the risks of outdated cryptographic algorithms and serves as a warning as modern encryption methods face similar threats.
