Detects the execution of PowerShell or Unix shell commands (such as those containing encoded arguments, IEX, or clipboard reading) that are initiated by GUI-based applications or interactive shell environments like Windows Explorer, terminal emulators, or runtime brokers, often indicating potential malicious command injection or living-off-the-land activity.
Detects rapid, closely-spaced network requests from the Microsoft Edge process (msedge.exe) to Microsoft-hosted domains within a very short timeframe. This behavior is indicative of a race-condition exploitation technique (CVE-2026-55945) intended to manipulate the Edge AI agent's state transitions, specifically forcing it from 'think' mode into 'act' mode to facilitate unauthorized command injection.
Detects anomalous POST requests containing the 'CrpxBoundary' string sent to a '/relay.php' endpoint. This signature is associated with the pre-encryption data exfiltration phase of CRPx0 ransomware.
Detects modifications to the Windows RunMRU registry key where the value contains suspicious strings such as 'powershell', 'curl', or long encoded strings. This behavior is indicative of potential command execution, persistence, or staging via the RunMRU list.
This rule detects the creation of Windows scheduled tasks using the 'schtasks.exe' utility or events generated when a task is registered. This technique is commonly used for persistence and execution by adversaries.
Detects modifications to registry keys associated with the 'ms-settings' COM object, specifically targeting the shell open command or DelegateExecute value. This technique, commonly referred to as 'ms-settings' hijacking, is used by adversaries to achieve persistence or elevated execution by redirecting legitimate COM object references to malicious payloads.
Detects the creation of a scheduled task configured to run under SYSTEM or a Service account, where the triggering process is not a recognized system binary (e.g., taskeng.exe, schtasks.exe). This pattern is often used for persistence or lateral movement by bypassing standard administrative task creation tools.
Detects the initiation of PowerShell by the Windows Explorer process (explorer.exe), which is often indicative of malicious activity such as lateral movement or execution of scripts originating from user-triggered actions. The rule flags command lines containing obfuscated patterns, bypass arguments, or encoded commands.
Detects when AI-powered development tools or coding assistants (such as Claude, Copilot, Gemini, or Codex) spawn suspicious child processes like command shells (cmd, powershell, bash, sh) or networking utilities (curl, wget, python). This behavior is highly atypical for integrated development environments and may indicate exploitation of the assistant's integration or malicious code execution.
Detects outbound network traffic directed to Bitbucket (via TLS/443) or using the git protocol (via port 9418). Such connections from internal systems to unverified or unauthorized external Git repositories may indicate malicious activity, including the potential installation of malicious plugins or code via supply chain compromises (e.g., Plugin4Shell).
