What happened

SANS ISC diary (March 17–24, 2026) covering multiple operational observations: a malicious Bash script that installs a GSocket backdoor (delivery vector unknown); honeypot/Cowrie log findings including portscans, a successful Telnet compromise, web access, and a distinctive echo payload string referencing “MAGIC_PAYLOAD_KILLER_HERE_OR_LEAVE_EMPTY_iranbot_was_here” observed from source IP 64.89.161.198; scans targeting database web frontends (notably Adminer and historically phpMyAdmin); discussion of IPv4-mapped IPv6 usage (RFC 4038) being used by attackers to obfuscate origin; and author tool
