This rule detects command-and-control (C2) communication patterns associated with the 'soraki-proxy.workers.dev' domain, a Cloudflare Workers-hosted proxy service. Additionally, it identifies potential malicious mTLS implants by flagging non-standard TLS handshakes that use self-signed or auto-generated certificates missing standard organization (O) fields in the subject DN.

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 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.
