🍯 Captured by **NullBlue67** via SSH honeypot — 2026-06-01.

Go DDoS botnet, internal module name "c2c/cmd/agent". HTTP flood via fasthttp (directhttp/betterhttp commands).
Persists as systemd "cpufreqd" disguise. Multi-arch (x86_64 + ARM aarch64). Go 1.26.3, debug_info not stripped (OPSEC fail). Possibly new family.
