show moreHoneypot targeted across 3 sessions via libssh 0.9.6 client. Creds attempted: 345gs5662d34/345gs5662d34, karan/3245gs5662d34, karan/karan@123. Command exec achieved. Activity: SSH key injection and persistence hardening. Attacker removed .ssh dir, recreated it, injected RSA pubkey (AAAAB3NzaC1yc2EAAAABJQAAAQEArDp4cun2lhr4KUhBGE7VvAcwdli2a8dbnrTOrbMz1+5O73fcBOx8NVbUT0bUanUV9tJ2/9p7+vD0EpZ3Tz/+0kX34uAx1RV/75GVOmNx+9EuWOnvNoaJe0QXx) into authorized_keys for credential-free access. Second cmd used chattr and lockr to set immutable flags on .ssh dir, blocking key removal/modification—hardening against remediation. Persistence typical of botnet or targeted intrusions. Credential spraying + SSH key persistence + filesystem immutability indicates systematic post-compromise hardening. libssh 0.9.6 suggests automated tooling. No malware dl or lateral movement observed.
