Detects payload staging activity associated with threat actor UAC-0099, correlating the creation or modification of executable/DLL files in disguised LocalAppData directories with decoy images or library configuration files within a one-hour window.

Detects Play-style lateral movement via Group Policy: an executable (.exe/.dll) written to a SYSVOL/GPO path by the same non-machine account that modified a GPO in the same 30-minute window. Attackers use this to push ransomware or Cobalt Strike/SystemBC payloads domain-wide.
This rule monitors endpoint telemetry (DNS queries, network connections, file creation, and process execution) to identify matches against a predefined list of known malicious indicators, including IP addresses, domains, and file hashes (SHA256). The rule differentiates between confirmed malicious activity and low-confidence indicators, providing a prioritized view of potential threats.
Hunting query, not intended as a scheduled alert.
Tested in a live Sentinel tenant with a test file. Copilot Cowork and Claude Code folder conventions not validated with live events; the Tool column is a label only and does not filter results. Matches files named SKILL.md in OneDrive and SharePoint only; local-only files and marketplace plugin skills are not visible.

Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.
Detects payload staging activity associated with threat actor UAC-0099, correlating the creation or modification of executable/DLL files in disguised LocalAppData directories with decoy images or library configuration files within a one-hour window.
Detects a suspected ClickFix social engineering attack where a user is tricked into pasting malicious commands into Windows Terminal, leading to a PowerShell download, followed by the appearance of specific known malicious artifacts (LockScreenContentServer.exe, dui70.dll, or 1.bat) within 15 minutes on the same device.
The following analytic detects the creation of shim database files (.sdb) in default directories using the sdbinst.exe application. It leverages filesystem activity data from the Endpoint.Filesystem data model to identify file writes to the Windows\AppPatch\Custom directory. This activity is significant because shims can intercept and alter API calls, potentially allowing attackers to bypass security controls or execute malicious code. If confirmed malicious, this could lead to unauthorized code execution, privilege escalation, or persistent access within the environment.
The following analytic detects the creation of files with extensions commonly associated with the Mimikatz Crypto module. It leverages the Endpoint.Filesystem data model to identify specific file names indicative of certificate export activities. This behavior is significant as it may indicate the use of Mimikatz to export cryptographic keys, which is a common tactic for credential theft. If confirmed malicious, this activity could allow an attacker to exfiltrate sensitive cryptographic material, potentially leading to unauthorized access and further compromise of the environment.
The following analytic identifies the creation of a .crmlog file within the %windows%\Registration directory, typically with a format of <RANDOM_GUID>.<RANDOM_GUID>.crmlog. This detection leverages the Endpoint.Filesystem datamodel to monitor file creation events in the specified directory. This activity is significant as it is associated with the Snake malware, which uses this file for its operations. If confirmed malicious, this could indicate the presence of Snake malware, leading to potential data exfiltration, system compromise, and further malicious activities. Immediate investigation is required to mitigate the threat.
Detects endpoint and network activity matching known Indicators of Compromise (IOCs) associated with BPFDoor, AVERAT, and Rekoobe backdoors based on Rapid7 research. The query checks for specific file hashes, IP addresses, and domain names across process, file, image load, network, and DNS events.
