A 54-day SSH honeypot on port 22 logged 268,000+ login attempts from 7,556 IPs, with 99.6% of attackers running a single automated fingerprinting command and only 28 ever opening an interactive shell. The data shows hardcoded IoT credentials and Solana validator hunting dominating the password lists.. read more
