Detects instances where a process named msedge.exe is running from the 'C:\ProgramData\Microsoft\Windows\Telemetry\' directory. This is a common location used by attackers to hide malicious executables by masquerading them as legitimate browser processes, particularly when the process command line includes arguments like 'preview' or 'thumbnail' which are often used to blend in with background system activity.

This rule detects network traffic originating from the local network to external destinations that exhibit characteristics associated with the Xray-core tool, specifically the use of a spoofed TLS Server Name Indication (SNI) of 'dl.google.com' paired with a server certificate that does not contain 'Google' in the subject. This technique is used to bypass network filters by masquerading command and control traffic as legitimate Google traffic.
Detects network traffic where the SilverFox malware relay (api.php) attempts to evade detection by returning a legitimate WeChat installer download link as a decoy response, rather than its intended malicious payload, when communicating with external analysis environments.
This rule detects the execution of the SentinelOne memory scanner process (SentinelMemoryScanner.exe) or the loading of the associated SentinelOne core library (SentinelAgentCore.dll) from a directory path outside of the standard SentinelOne installation locations (Program Files\SentinelOne or Program Files (x86)\SentinelOne). This behavior is indicative of potential masquerading or tampering where an adversary attempts to execute a renamed or moved security tool to bypass policy or evade detection.
Detects the Kimsuky second-stage payload test.bef_fri which masquerades as an RTF file via a falsified RTF header before header repair and decompression
This rule identifies the execution of specific binaries (Kingsoft Office suite and Onkey/Tendyron components) from suspicious or uncommon directories such as temporary folders, user downloads, or public directories, which may indicate the staging and execution of malicious payloads masquerading as legitimate software.
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.
Detects instances of vsdbg.exe (Visual Studio Debugger) loading vsdbg.dll from suspicious, temporary, or user-controlled locations (e.g., Temp, Downloads, AppData) when initiated from a path outside of the standard Microsoft Visual Studio installation directories. This behavior is indicative of potential masquerading or side-loading of the debugger utility by an attacker.
Detects the execution of processes with suspicious file names that are commonly associated with masquerading, potentially impersonating legitimate software or system tools.
This rule detects potentially malicious activity by monitoring the execution of Python interpreters or specific suspicious executable names from within the C:\ProgramData directory. The detection logic focuses on processes launching from directories associated with configuration or data storage folders, often used by malware for staging or execution to avoid detection. It specifically flags Python execution involving certain suspicious file or argument strings, and the launch of named executables (e.g., RuntimeSSH.exe, smqdservice.exe) located in specific ProgramData subdirectories.
Detects instances where the 'msedge.exe' binary is executed from the non-standard path 'C:\ProgramData\Microsoft\Windows\Telemetry\', excluding instances initiated by the legitimate Microsoft Edge Update process. This pattern often indicates masquerading, where an adversary places a malicious file with a legitimate name in an attempt to evade detection.
This rule monitors for processes named 'msedge.exe' executing from the 'C:\ProgramData\Microsoft\Windows\Telemetry\' directory. The rule filters out legitimate Edge update processes and common browser command-line arguments to isolate potentially malicious masquerading attempts by identifying binaries that share the name of a legitimate application but reside in unexpected, often non-standard locations.

This rule detects the execution of 'vsdbg.exe', the Visual Studio Remote Debugger, from non-standard directories (e.g., Downloads, AppData, Temp, ProgramData) or in conjunction with the creation of 'vsdbg.dll' files. Adversaries may utilize this debugger for remote code execution or to bypass security controls by masquerading as a legitimate development tool.
