Detects network connections, process command-line executions, and email URL info matching known APT28 (Swallowtail, HOOKEDGE, LegionRelay) indicators of compromise, including specific IP addresses and GUIDs.

Detects the creation or modification of Windows Registry Run or RunOnce keys where the associated executable path is located in suspicious or non-standard directories (e.g., Temp, AppData, ProgramData). This behavior is characteristic of adversaries, such as APT28, attempting to maintain persistence by ensuring malicious code executes automatically upon user login.
Detects Microsoft Outlook initiating outbound SMB or WebDAV network connections to external IP addresses. This behavior is indicative of exploitation of CVE-2023-23397, where a malicious reminder sound or attachment forces the victim's client to authenticate against an attacker-controlled remote share, potentially leaking NTLM hashes.
Detects outbound HTTP requests or TLS traffic to known C2 domains associated with APT28/UAC-0001 related to the CVE-2026-21509 campaign.
Detects outbound HTTPS connections to major generative AI inference endpoints originating from non-browser, non-development tool processes at regular intervals. This activity is indicative of beaconing behavior, where malware (specifically families like LAMEHUG) leverages LLM APIs for dynamic command generation, payload obfuscation, or C2 instruction retrieval, bypassing traditional security controls.

This rule detects file creation and process execution events associated with specific SHA256 hashes linked to the APT28 threat actor exploiting CVE-2026-21509.
Detects the creation of a scheduled task named 'OneDriveHealth', which is associated with APT28 activity. This task is used for persistence via COM hijacking; it executes 60 seconds after registration, kills and restarts explorer.exe to facilitate the loading of a hijacked COM object, and subsequently removes itself.
This rule detects activities associated with the NotDoor malware used by APT28 for email-based exfiltration. It specifically monitors for the creation of staging files in temporary directories, the use of Outlook.exe to establish external SMTP connections on common mail ports, and the transmission of emails to known adversary-controlled addresses.
