Detects BeaverTail JavaScript-based loader malware hidden inside NPM packages, distributed via GitHub or Bitbucket during fake technical interviews
Detects instances where PowerShell scripts are executed via the Windows Task Scheduler from within potential staging directories (ProgramData with randomized folder names). The rule identifies execution that uses common PowerShell obfuscation flags (e.g., -EncodedCommand) and requires secondary hardening bypass flags (e.g., -WindowStyle hidden), followed by correlated network activity to a specific suspicious C2 domain.

Detects the handshake process of the frpc (Fast Reverse Proxy Client), which is associated with the RatHat malware family, attempting to register a reverse tunnel for command and control purposes.
This rule identifies the execution or presence of files matching a known list of MD5 hashes associated with malicious activity. By monitoring file metadata, this rule flags instances where specific identified threat files are present on the system.
Detects architecture-specific Mach-O 64-bit AMOS Stealer binaries dropped by the Macfinger ClickFix first-stage shell script, requiring multiple distinctive C2 endpoint strings alongside Mach-O magic and size constraints to reduce false positives

Detects the RatHat malware agent (liblocal-service.so) being staged in the Android /data/local/tmp directory and the subsequent execution of an ADB shell command to automatically re-install the malicious APK, ensuring persistence even after the application has been uninstalled.
This rule detects the execution of a malicious PowerShell command chain initiated by explorer.exe, consistent with the PlugX malware infection sequence. The detection monitors for specific command-line arguments, including the use of curl for file downloads, tar for extraction, and the launching of associated malicious executables like 'GRrte.exe' following the execution of a shortcut file named 'OIC_Invitation_General_Official.lnk'.
Detects specific samples of the Rmrlx information stealer by identifying unique file artifacts, mutex names (e.g., Global\EVOLUTION), and debugging/staged files commonly associated with its execution environment, including samples exhibiting IP-checking evasion techniques.
This rule detects potential malicious activity by monitoring for known malicious file hashes (MD5) across file and process events, and correlating them with known Command and Control (C2) infrastructure communication patterns, including specific IP addresses and URI paths.
Detects outbound network connections to known command-and-control IP addresses associated with the SpiceRAT malware family. The rule monitors DeviceNetworkEvents for successful connections or connection attempts over ports 80 and 443.
Detects the execution of RatHat, a Go-based Android native daemon masquerading as 'liblocal-service.so'. The rule identifies the malware's use of ADB-derived shell commands to bypass Android Doze mode, prioritize background execution, and tamper with installed applications via pm (package manager) commands.
IOC hunt for the HEAVYGRAM/CRUDEEXCLUDE campaign: matches known SHA256 file hashes (first-stage malware, implant, RAR/ZIP artefacts) via DeviceFileEvents and DeviceProcessEvents, plus known-malicious domains/staging infrastructure by parsed hostname across network connections, process command lines, and file origin URLs.
This rule monitors network, file, and process telemetry for matches against a predefined list of malicious IP addresses, domain names, and file hashes. It flags suspicious network connections to known C2 infrastructure and the presence or execution of known malicious files based on SHA256 and SHA1 indicators.
