VerdantBamboo BRICKSTORM Cron/RC Persistence on Edge Appliances

Detects unauthorized or suspicious modifications to critical Linux configuration directories (e.g., cron, rc, init, ipsec) or specific application-related paths by processes not typically associated with system management or package maintenance. The rule further elevates risk when specific indicators like LD_PRELOAD, LD_LIBRARY_PATH, or known malicious string artifacts are present in the command line or file path.
