What it detects

This rule detects HTTP access to the MOVEit Transfer machine2.aspx endpoint, which Assetnote identified during patch diffing as an internal-only interface reachable through SSRF in CVE-2023-34362. External or unexpected requests to this endpoint indicate an attacker has pivoted past the intended trust boundary. Because legitimate clients should not reach machine2 directly, such access is a strong exploitation signal.
