Detects execution of the tar utility by the prl_disp_service process with a command line pattern indicative of command injection via the --use-compress-program flag. This technique is often used to execute arbitrary commands by embedding them within the compression program argument.
Detects instances where the Parallels dispatcher service (prl_disp_service) is invoked to install an appliance using a local 'file:///tmp/' URL instead of a trusted remote catalog source, which may indicate an attempt to load unauthorized or malicious virtual appliance files.

Detects the execution of the Windows Character Map utility (charmap.exe) when launched from a user-writable Temp directory by a non-standard parent process. This pattern is commonly associated with malware, such as AsyncRAT, attempting to leverage legitimate system tools to evade detection or facilitate malicious chains.
This rule detects activity matching known indicators of compromise (IOCs) associated with recent Russian espionage campaigns, including malicious domains, IP addresses, email senders, file names, and file hashes. It monitors network, sign-in, email, process, and file events across enterprise systems.
Detects the execution of PowerShell scripts located in the user's temporary folder. The detection logic looks for common obfuscation flags such as WindowStyle Hidden, NoProfile, and NoLogo, combined with the -File argument, which are frequently used by droppers and malicious payloads to execute scripts in the background while evading immediate user observation.
This rule detects PowerShell commands that utilize specific character array joining techniques (e.g., [char]nnnn -join '') often used to obfuscate malicious strings or bypass keyword-based security filters. This is a common tactic for evading detection when downloading or executing payloads.
Detects child processes spawned by 7z.exe when it is executed from the 'C:\Users\Public\Documents\' directory. This is consistent with the behavior of the GRAYRABBIT backdoor, where a trojanized 7z.dll or boy.dll is sideloaded into the 7z.exe process to facilitate silent arbitrary process execution.

Detects ROOFDECK backdoor persistence via macOS Launch Agents, tightened to require the implant's distinguishing masquerade artifacts (fake Apple-service drop paths, --type=renderer flag, loginwindow.plist impersonation, or the literal 'persist add|remove|check' CLI syntax) rather than generic LaunchAgents plist creation or launchctl load activity, which legitimate macOS software triggers constantly.

Detects indicators of compromise related to the TraderTraitor (KelpDAO) threat actor, including specific file hashes, malicious process paths, C2 network infrastructure (IPs and domains), and malicious TLS certificates. The rule uses filename-path matching to reduce noise from legitimate macOS binaries.

The rule uses filename-path matching to reduce noise from legitimate macOS binaries.
Detects the execution of known PAPERMILL/VenomRAT loader samples, identified by specific suspicious file names. The detection monitors for the initiation of these processes, followed by a delayed (5-10 minutes) creation of RunOnce registry persistence entries that masquerade as RuntimeBroker.
Detects Git checkout operations involving specific SHA hash arguments that occur in conjunction with potential ambiguous refname errors, or are initiated by processes commonly used for AI-assisted coding (e.g., Copilot, Claude). This rule monitors for potentially malicious source code repository manipulation or automated branch hijacking attempts, often seen in supply chain or development environment attacks.
This rule detects the presence or execution of a specific file on a device, identified by its SHA256 hash. The rule monitors both file creation/access and process execution events to identify if a known malicious binary is interacting with the system.
This rule monitors for the presence of files matching a known list of malicious SHA256 hashes on devices. It correlates these file events with process creation events occurring on the same device within a 10-minute window, identifying potential execution of malicious binaries or artifacts.
Detects evidence of persistent Android malware attempting to maintain access. It identifies the execution of a hidden Go-based daemon masquerading as a shared library in temporary storage, silent reinstallation of malicious APKs using package installer flags, and automated re-granting of accessibility services to bypass user interaction requirements.
Detects the RatHat Android malware attempting to perform a UI overlay attack by requesting the SYSTEM_ALERT_WINDOW permission while specifically targeting payment application packages, such as WeChat (com.tencent.mm) and Alipay (com.eg.android.AlipayGphone), to capture sensitive credentials.
