UAT-8616 SD-WAN Persistence: troot Account Creation and SSH Key Implantation
Detects unauthorized persistence mechanisms on Cisco SD-WAN Manager, vSmart, and vBond nodes by monitoring for local account creation (e.g., useradd), modification of sensitive authentication files (/etc/passwd, /etc/shadow), and illicit SSH key placement in authorized_keys. This rule specifically monitors for known exploit paths involving the 'troot' account and related command-line activity indicative of unauthorized administrative access.
