Detects the use of the Windows 'tasklist' utility or command execution via 'cmd.exe' when the command line includes strings associated with common debugging tools (e.g., windbg, x64dbg). This behavior may indicate an adversary checking for the presence of analysis tools or attempting to manipulate running processes, which is often associated with debugger evasion or malicious environment reconnaissance.

Detects Android malware performing anti-debugging, anti-instrumentation, and environmental checks to evade analysis. The rule monitors for processes querying system properties, checking for debugging artifacts like TracerPid, attempting to locate Frida instrumentation agents, or identifying rooting/Xposed framework artifacts and emulator-specific files.

Detects a suspicious sequence of anti-analysis behaviors on macOS, where a process first checks for the presence of a hypervisor via sysctl (kern.hv_vmm_present) and subsequently invokes ptrace with PT_DENY_ATTACH, a technique often used to prevent debuggers from attaching to a process.

Detects instances of process call stack spoofing, specifically techniques like SparroWocky (hooking CreateThread to report fake start addresses such as AnimateWindow) or SilentMoonwalk (forged call stacks masking API call origins as RtlUserThreadStart or BaseThreadInitThunk) used to evade EDR behavioral monitoring.

This rule detects PowerShell command lines that include .NET API calls typically used for anti-debugging and anti-analysis evasion, such as 'Debugger.IsAttached', 'Debugger.IsLogging', 'CheckRemoteDebuggerPresent', and 'Environment.FailFast'. These checks are common in malicious loaders and implants to determine if the process is being analyzed or monitored, allowing the malware to modify its behavior accordingly.

This rule detects potential anti-debugging behavior characteristic of the ConfuserEx packer. It identifies processes that repeatedly poll for debugger presence (using APIs such as Debugger.IsAttached, Debugger.IsLogging, or CheckRemoteDebuggerPresent) at approximately 1-second intervals, culminating in a call to Environment.FailFast to terminate execution if a debugger is detected.

Detects a suspicious PowerShell process lineage spawned by explorer.exe that exhibits characteristics of a 'ClickFix' social engineering lure (using obfuscated command lines) and proceeds to inject code into legitimate Windows or browser processes such as csc.exe, chrome.exe, msedge.exe, or SearchIndexer.exe. This activity is often associated with malware attempting to evade debugging.

This rule detects PowerShell commands that enumerate system, security, or virtualization-related artifacts. It specifically looks for the usage of WMI and PowerShell cmdlets (e.g., Get-Process, Get-WmiObject) to query for known analysis tools, debuggers, or virtualization software strings, which is a common behavior of malware attempting to identify and evade sandbox or analyst environments.

Detects .NET malicious payloads associated with the StealC info-stealer by identifying anti-debugging and anti-analysis routines. The rule specifically looks for the usage of System.Diagnostics.Debugger methods (IsAttached, IsLogging), native debugger presence checks (IsDebuggerPresent, CheckRemoteDebuggerPresent), and Environment.FailFast usage, often in combination with obfuscation markers like ConfuserEx.

This rule detects processes accessing '/proc/self/status' to read the 'TracerPID' field. Malware often uses this technique to detect if it is being debugged or traced by security analysis tools, allowing the process to terminate or change behavior to avoid analysis.
