Detects network activity or command line parameters initiated by the Jarte text processor (Jarte.exe or GRrte.exe) originating from a JartePortable directory, indicating potential C2 activity involving the domain 'castanaksa.com' or the IP address '192.64.119.189'.
This rule detects periodic network beaconing patterns consistent with BabylonRAT malware. It flags established TCP connections to external networks that occur at a frequency exceeding 5 connections within a 300-second window, which may indicate a C2 check-in mechanism. Due to the heuristic nature of this detection, it is recommended to tune the threshold and correlate with payload analysis or entropy inspection to reduce noise.

Detects network activity associated with the DarkMe RAT, including DNS lookups for its known C2 domain 'thatawful.boutique' and outbound TCP connections to a hardcoded non-standard port (7712) at a known malicious C2 IP address.
Detects outbound TCP traffic from the internal network to external destinations that match characteristics of Gorilla RAT registration beacons. This includes established sessions with small packet sizes (<64 bytes) and frequent, repeated attempts as defined by the threshold.
Detects outbound network connections to known command-and-control (C2) infrastructure associated with SpiceRAT, including specific malicious IP addresses and domain names used for decoy content delivery.
Detects outbound network connections to 'acrobat-updater.com' involving suspicious API paths that mimic the Adobe Acrobat updater. This may indicate an attempt by an adversary to masquerade malicious command and control or data exfiltration as legitimate update traffic.
Detects network traffic (DNS queries, TLS SNI, and HTTP Host headers) targeting the domain 'expresshost.cloud', which is identified as hosting VPS infrastructure commonly used for scanning and malicious activities.
This rule detects network upload operations (HTTP POST or similar requests ending in '/upload') to a specific external IP address (2.26.126.50). It specifically monitors for processes other than common web browsers, and filters for connections where significant data volume (greater than 10KB) is transferred or the data size is unknown.

This rule monitors endpoint telemetry for occurrences of known malicious file hashes, C2 IP addresses, and C2 domains. It aggregates file creation/modification events, process execution, and network connections to detect activity associated with known malicious entities.
This rule identifies successful network connections from local devices to a predefined list of known malicious IP addresses within the last 7 days. Such connections often indicate active communication between a compromised endpoint and adversary-controlled infrastructure.
This rule monitors for known malicious file hashes (MD5) and network traffic (domains and specific URLs) associated with known threats. It aggregates events from DeviceFileEvents, DeviceProcessEvents, and DeviceNetworkEvents to identify potential interactions with threat infrastructure.

Detects the Comet browser process, typically associated with AI-agent operations, accessing sensitive browser profile files (e.g., History, Bookmarks, Login Data, Cookies) followed by outbound network communication within a 15-minute window, excluding known legitimate paths.

Detects network activity (DNS lookups, TLS SNI, and HTTP Host headers) associated with proxy infrastructure (iproyal.com and lightningproxies.net) known to be used by the HEAVYGRAM/CHOSEN BRICK threat actors to mask Telegram-based command and control traffic.
This rule monitors various logs (device network events, Entra ID sign-ins, cloud application events, and email events) for any interaction with a predefined list of indicator IP addresses identified as being associated with malicious actor egress traffic.
