show moreCredential brute-force attack using libssh 0.9.6 library. Three login attempts with weak credentials: 345gs5662d34/345gs5662d34, panel/3245gs5662d34, panel/panel@123. Attack succeeded on at least one session. Attacker executed SSH key injection for persistence: removed existing .ssh directory, created new one, and injected RSA public key (AAAAB3NzaC1yc2EAAAABJQAAAQEArDp4cun2lhr4KUhBGE7VvAcwdli2a8dbnrTOrbMz1+5O73fcBOx8NVbUT0bUanUV9tJ2/9p7+vD0EpZ3Tz/+0kX34uAx1RV/75GVOmNx+9EuWOnvNoaJe0QXx) into authorized_keys. Second command chain attempted to modify file attributes using chattr -ia on .ssh directory and executed lockr command (likely typo for chattr; lockr not standard utility), suggesting effort to prevent removal of implanted SSH keys. Attack pattern indicates automated credential stuffing followed by immediate persistence establishment via SSH key injection. Timeline spans 6 seconds across 3 sessions.
