show moreBrute-force credential attacks targeting root account using 45 unique weak password combinations. Attacker used Go-based SSH client across 54 sessions. Credentials ranged from simple numeric sequences (111111, 123, 123123) to common patterns (password, qwerty, admin123, P@ssw0rd, root variations). Upon successful authentication, executed system reconnaissance commands: export PATH statement to ensure command availability, followed by uname -s -v -n -m to enumerate OS type/version/hostname/architecture, and /proc/uptime retrieval to determine system uptime. No persistence mechanisms, lateral movement, downloads, or malware observed. Activity suggests automated scanning/enumeration phase typical of botnet reconnaissance or initial access preparation. Successful credential compromise likely given 54 total sessions from single IP within 16-minute window.
