What happened
SANS ISC observed a malicious Bash script that installs a GSocket backdoor on a victim host; the source and delivery vector are unknown. Related diary entries describe widespread scanning activity (phpMyAdmin/adminer scans, /proxy/ URL probes), use of IPv4-mapped IPv6 addresses to obfuscate origin, and cowrie honeypot logs showing a banner-like payload string ("MAGIC_PAYLOAD_KILLER_HERE_OR_LEAVE_EMPTY_iranbot_was_here"), plus successful Telnet login and web access from IP 64.89.161.198. No CVE or vulnerability linkage was provided in the report.
