Sweeps file, process and image-load telemetry for known Kimsuky (APT-C-55) malware MD5 hashes. Exact hash matches carry very low false-positive risk.
The following analytic detects the wermgr.exe process creating an alternate stream in the temp directory. It leverages Sysmon EventID 15 to identify these actions.
This activity is significant because wermgr.exe is typically associated with error reporting, not file creation. Such activity is significant as it may indicate RoguePlanet malware, which creates an alternate stream in the temp directory to execute malicious code.
If confirmed malicious, this could lead to further malware infections, data exfiltration, or system compromise.

Detects the execution of archiving utilities (7z, rar, tar, or Compress-Archive) targeting configuration directories of AI coding assistants such as Claude, Codex, Cursor, and Gemini.
Sweeps file, process and image-load telemetry for known Kimsuky (APT-C-55) malware MD5 hashes. Exact hash matches carry very low false-positive risk.
Detects processes accessing sensitive files and configurations associated with multiple AI coding assistants (such as Claude, Codex, Grok, and Cursor) within a short time window, potentially indicating unauthorized access or credential theft from AI tools.
Detects the presence of known Candiru Windows DLL implant IOC hashes across device file events, process events, image loads, and email attachments.
IOC sweep (SHA256, domains, URLs, IPs, sender emails) for the RedFlick-style VHDX/LNK/WebDAV campaign against Moldovan and Ukrainian civil society, with false-positive controls.
Detects the creation of new files with the ".evtx" extension in non-common or non-standard location.
This could indicate tampering with default EVTX locations in order to evade security controls or simply exfiltration of event log to search for sensitive information within.
Note that backup software and legitimate administrator might perform similar actions during troubleshooting.

Detects the presence of known MD5 file hashes associated with the TraderTraitor trojanized Terraform provider campaign (also known as FLATROOF/ROOFDECK). The query sweeps DeviceFileEvents, DeviceProcessEvents, and DeviceImageLoadEvents across the last 30 days.
Sweeps Defender XDR telemetry for known NEBULA / KNTRAT indicators (SHA256 hashes, C2 IP, decoy domain and URLs, burner publisher emails). Hash matching is scoped per table (execution hash only in process events), noisy tooling is excluded from command-line matches, network hits are limited to connection events, and results are aggregated per device and IOC.
Correlates ARTEX tool artifacts on a device with that device contacting the ARTEX host, xcai.pro, or the DeepSeek API within 24 hours.
Sweeps endpoint telemetry for known UAC-0099 MATCHBOIL/LONEPAGE indicators: SHA256 hashes, C2 IPs, C2 domains (including subdomains), and payload/C2 URLs. Matches are limited to public outbound connections, Defender self-activity is excluded from file hits, and repeat hits are collapsed to one row per device and indicator. The lists are a subset of the 142 IOCs in the source report.
Performs an IOC sweep for a known XMRig cryptojacking campaign exploiting a REDCap vulnerability (CVE-2026-90817), detecting matching network connections, file hashes, and process activities across endpoints.
Detects the presence of known MD5 file hashes associated with the TraderTraitor trojanized Terraform provider campaign (also known as FLATROOF/ROOFDECK). The query sweeps DeviceFileEvents, DeviceProcessEvents, and DeviceImageLoadEvents across the last 30 days.

Point-in-time sweep of the 16 published BraZetsu sample SHA-256 hashes across file, process and image-load telemetry. Hashes rotated across five versions, so absence of a hit does not rule out BraZetsu.
