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.

Detects endpoint behavior consistent with AI-assisted exploit development, characterized by the execution of reverse engineering and vulnerability research tools (e.g., IDA Pro, Ghidra, AFL) interleaved with frequent outbound network connections to LLM APIs, followed by the local compilation of a new executable or DLL.

001
Detects anomalous, high-volume file access by a single process, followed by local file compression or archiving, and subsequent outbound data transfer to a non-internal IP address. This pattern is characteristic of automated agents (like those used in the GTG-1002/Anthropic AI-orchestrated campaigns) performing rapid data triage and staging for exfiltration.

001
Detects the execution of common remote monitoring and management (RMM) software on a host shortly after the associated user account underwent a password or MFA reset, a pattern indicative of help-desk impersonation (vishing) followed by unauthorized remote access setup.

Detects the execution of known remote access or remote monitoring software (such as TeamViewer, AnyDesk, or ScreenConnect) on corporate-issued Windows endpoints. The rule triggers on process execution patterns associated with unauthorized remote control, specifically looking for indicators of unattended access or silent installation commonly used by overseas actors to remotely operate company-issued laptops assigned to fraudulently hired identities.

003
Detects instances where Microsoft Visual Studio Code (Code.exe) spawns common interpreters or command-line tools (such as node, python, cmd, or powershell) that are not associated with known internal VS Code process behaviors like renderer tasks or tunnel operations. This activity may indicate malicious use of the integrated terminal or extension execution contexts to execute unauthorized code.

003
Detects instances where node.exe or npm processes spawn a Python interpreter. This behavior is indicative of malicious activity, specifically the execution of second-stage payloads such as the InvisibleFerret backdoor often associated with the BeaverTail JavaScript loader, observed in software supply chain compromise campaigns.

Detects the creation or modification of registry entries within the 'HKCU\...\Run' hive that point to executables located in suspicious or atypical directories such as 'ProgramData', 'Users\All Users', or specific non-standard application paths often used by malware for persistence.

Detects instances where a desktop messaging application (WhatsApp or Telegram) spawns a child process that matches known suspicious naming conventions or lure keywords, suggesting that a user has executed a malicious file shared via the platform.

Detects the creation of image files (.bmp, .png, .jpg, .jpeg) by processes executing from non-standard directories such as AppData or ProgramData. This behavior is indicative of unauthorized screen capture activities often used by malware for pattern-of-life monitoring, where screenshots are staged in temporary locations before exfiltration. The rule filters out common legitimate applications known to perform screen captures.

003
Detects instances of common interpreter processes, specifically node.exe or python variants, accessing known cryptocurrency wallet files or mnemonic storage files on a Windows system. This behavior is highly indicative of malicious activity where an attacker uses lightweight script-based tools to perform credential harvesting or theft of cryptocurrency assets.

Detects the deletion of Volume Shadow Copies using the Windows Management Instrumentation Command-line (WMIC) utility. This behavior is commonly observed in ransomware attacks, including those attributed to DragonForce and CRPx0, as a method to inhibit system recovery prior to file encryption.

Detects instances where a non-browser process initiates connections to commercial LLM provider APIs (DeepSeek, OpenRouter, Mistral) followed by a connection to Discord CDN/Webhook endpoints within a 15-minute window. This behavior is indicative of a process acting as an autonomous C2 agent that exfiltrates data after receiving instructions or processing information via an LLM.

Detects the deletion of 'loader.js' from the '%APPDATA%\VSCODE\' directory. This activity is consistent with the initial execution phase of GHAPPIER RAT, where the implant removes its dropper file to avoid detection and hinder forensic analysis.

This rule detects potential credential theft by correlating access to local git credential files (e.g., .git-credentials, .netrc) followed by a git push event from the same user account within 24 hours. The rule flags these pushes if they originate from an unrecognized host or an IP address outside of the trusted internal network range.

Detects instances where npm.exe or node.exe initiate child node.exe processes, a behavior commonly associated with multi-stage loaders or malicious packages (e.g., GHAPPIER) that execute arbitrary JavaScript payloads during package installation or execution.

Detects a process that deletes its own executable file immediately after launching. This anti-forensic behavior is commonly utilized by remote access trojans (RATs) and other malware to minimize their footprint and evade file-based forensic analysis.

Detects the execution of rundll32.exe with a command line containing 'DavWWWRoot', indicating the loading of a DLL payload directly from a remote WebDAV share. This behavior is commonly associated with ClickFix/ClearFake infection chains where users are tricked into executing malicious payloads hosted on attacker-controlled WebDAV servers.
