show moretempted credential spray across 3 sessions using libssh 0.9.6 library. Credentials tested: 345gs5662d34/345gs5662d34, root/3245gs5662d34, root/Aa147258@. Two distinct command sequences executed targeting SSH key management and file attributes. First command chain removes existing .ssh directory, creates new one, and injects RSA public key (AAAAB3NzaC1yc2EAAAABJQAAAQEArDp4cun2lhr4KUhBGE7VvAcwdli2a8dbnrTOrbMz1+5O73fcBOx8NVbUT0bUanUV9tJ2/9p7+vD0EpZ3Tz/+0kX34uAx1RV/75GVOmNx+9EuWOnvNoaJe0QXx) for persistence. Second command attempts to remove immutable file attributes from .ssh directory using chattr, followed by lockr command (likely typo or malformed variant). Attack demonstrates SSH key injection persistence mechanism combined with file attribute manipulation to prevent removal. Rapid session succession (10 seconds total) suggests automated scanning tool. No downloads or lateral movement observed. Threat consistent with opportunistic SSH credential brute-forcing campaigns targeting exposed services.
