show moreBrute force attack: 13 common creds against root across 14 sessions. Successful auth led to multi-stage malware deployment. Cmd exec from /tmp w/ ulimit -n 1020000 (resource-intensive ops). Cleanup cmd (rm -rf meow*) removed prev artifacts before fresh dl. Two malware binaries dl'd from 34[.]83[.]130[.]213 via wget/curl: "meow" (6.5MB, sha256:45bff40a22d87575c6dd47fb5a1cdade428c08771f50c357ac9001f3f6f1279a) and "meowarm64" (6.0MB, sha256:678aaed50cc6993016653b501585bc4073a60c36c3301a1a45c5fa6c39cdceb3). Both chmod 777'd and exec'd immediately. "meowarm64" filename suggests ARM64 targeting for multi-platform distribution. Cred list: Welcome123, qwerty variants, letmein, secret, calvin. Pattern consistent w/ automated botnet propagation using credential stuffing+payload deployment. Six-min attack window indicates scripted recon/exploitation cycle.

show moreGo-based SSH client executed 14 login attempts with 13 common passwords against root account (6-min window). Single cmd chain across 12 sessions: cd /tmp, ulimit -n 1020000, rm meow*, wget/curl dl from 34[.]83[.]130[.]213. Downloaded: meow (executable), meowarm64 (ARM64 variant). Set execute perms, ran meow binary. Pattern indicates automated botnet reconnaissance/worm propagation targeting exposed SSH services. High FD limit increase suggests resource-intensive ops (multiple connections/crypto mining). Complete cmd chain executed on systems with weak creds. Represents successful compromise vector for vulnerable hosts in scanning range. Meow malware family observed in previous campaigns targeting SSH services.
