This rule detects potential command and control (C2) communication related to the GhostContainer malware. It inspects HTTP POST requests directed at Microsoft Outlook Web Access (OWA) paths containing a suspicious 'x-owa-urlpostdata' header. The presence of this specific header, followed by a base64-encoded string of significant length, indicates an attempt to deliver C2 commands or exfiltrate data through OWA infrastructure.

Detects anomalous network traffic patterns where internal assets interact with Microsoft Graph API and Entra ID (login.microsoftonline.com) authentication endpoints from distinct external destination IPs within a short time window. This behavior is indicative of potential attacker infrastructure rotation during C2 or post-authentication phases.

Detects outbound network traffic from internal hosts to the Microsoft Graph API (graph.microsoft.com) originating from Python HTTP clients (requests or urllib libraries). This pattern can indicate automated data exfiltration from an internal environment to a cloud-based service, or the use of Microsoft Graph API for command and control purposes.

Detects TCP connections on standard web ports from internal hosts to known IronToll C2 IPs on Tencent/Alibaba Cloud. Scoped to web ports and an established handshake, with a per-source hourly alert cap to reduce repeat noise.

Detects DNS queries for lookalike domains combining a government/brand-impersonation keyword (as its own label, not a substring) with a disposable TLD used across the IronToll campaign. Dropped the standalone 'digital' keyword, which was generic enough to match ordinary e-commerce domains on the same TLDs.

Detects country-coded lure path requests (/eg, /ma) followed by a cloaking differential response (desktop UA blocked with 404, mobile UA served content). Fixed a regex bug where the original pattern matched any path merely starting with 'eg' or 'ma' (e.g. /egg.jpg, /mail, /manifest.json) instead of the exact path segment.

This rule monitors TLS traffic for a specific combination of certificate issuer Common Name (CN) matching 'YE1' and Server Name Indication (SNI) hostnames using known disposable or high-risk top-level domains (TLDs). This behavior is associated with the IronToll campaign, often indicative of command-and-control communication or malicious infrastructure staging.

Detects possible unauthenticated exploitation attempts against CVE-2025-53521 (F5 BIG-IP APM RCE). Tightened from a generic 'any POST without a cookie on 443/8443' match (extremely broad, alerts on ordinary cookie-less API/health-check traffic) to POST requests specifically targeting F5 APM access-policy processing endpoints (/my.policy, /vdesk/) that lack a session cookie, since the CVE requires an access policy configured on the virtual server and legitimate APM sessions carry a session cookie. Added detection_filter (3 hits/60s per source) to suppress single incidental matches and prioritize repeated attempts. Note: public reporting for this CVE does not include the exact exploit URI/payload, so this is a behavioral/namespace heuristic, not a payload-specific signature — validate against your own APM traffic baseline and update once exploit specifics are published.
