What it detects

This rule detects the VAPT confirmation markers and command placeholder that attackers wrap around executed commands when validating remote code execution with offensive agentic tooling built on stolen AI compute. The markers bracket command output so the automation can parse successful execution. Their appearance on hosts is a high-confidence sign of automated exploitation.
