Scans for Sshole Vulnerability (CVE-2026-123158), (Sun, Nov 8th)
Our honeypots use "Cowrie" to collect SSH data. With the emergence of the "sshole" vulnerability last week, we are now seeing an increase in attempts to exploit the vulnerability. Our data is a bit limited in this respect. Our honeypots collect only the first 255 characters of SSH passwords. Longer passwords are highly unusual and not used for the usual password brute-forcing we observe.
