This rule detects potential exploitation of vulnerabilities (such as CVE-2026-33017) where mshta.exe or wscript.exe spawns PowerShell, followed by the addition of a persistent entry to the HKCU Run registry key targeting Node.js or JavaScript files.
Detects instances where the Windows Error Reporter (wermgr.exe) process attempts to open a handle to a Volume Shadow Copy (VSS) device. This behavior is anomalous as legitimate VSS operations are typically performed by dedicated system processes (e.g., vssvc.exe, diskshadow.exe), and such access by wermgr.exe may indicate an attempt to bypass file locks for credential dumping or sensitive data exfiltration.
Detects anomalous SSH connections originating from internal network appliances or DMZ-segment devices (e.g., storage, firewalls) to multiple internal network hosts. This behavior is indicative of lateral movement or SSH tunneling as observed in the VerdantBamboo BRICKSTORM campaign, where edge devices are leveraged as pivot points.
Detects activity associated with the RoguePlanet exploit, which involves creating EICAR content and NTFS Alternate Data Streams (ADS) within specific staging directories (wdtest_temp or RP_<UUID>). This behavior is intended to trigger Windows Defender scans and induce a TOCTOU race condition (CVE-2026-50656) by manipulating file operations near the wermgr.exe process.
Detects indicators of persistence on Linux systems, specifically targeting unauthorized cron job creation/deletion in /etc/cron.d/, execution of suspicious shell scripts (ssync.sh), modification of startup scripts (e.g., /etc/rc.d/cron), and execution of binaries from world-writable directories by cron or system daemons. This rule is designed to identify the footprint of known Linux-based persistence mechanisms associated with service account exploitation.
Detects the spawning of conhost.exe as a child process of wermgr.exe, an anomalous behavior indicative of the RoguePlanet exploit chain (CVE-2026-50656) which uses a Defender quarantine pipeline junction hijack to replace the legitimate Windows Error Reporting manager. Standard operations of the legitimate wermgr.exe process do not involve launching interactive console hosts.
Detects the Yuta .NET WPF dropper (SLaunch.exe) executing and subsequently creating a secondary payload (winupdate.exe) within the AppData\Roaming\.cache directory. This pattern is characteristic of the Yuta/Glove Stealer infection chain where a dropper masquerading as a UI component stages a PyInstaller-compiled stealer binary.
Detects unauthorized processes, such as PyInstaller binaries or Python scripts, attempting to read LevelDB storage files used by popular messaging applications (Discord, Telegram, Signal, Slack, and Microsoft Teams) for session and authentication token extraction, a technique commonly associated with information stealers like Yuta or Glove Stealer.
Detects the creation of suspicious scheduled tasks by potentially malicious processes (e.g., winupdate.exe or processes running from AppData/.cache or Temp directories). The rule monitors for schtasks.exe usage that either targets specific persistence locations or creates tasks naming conventions (e.g., 'WindowsDefenderAgent') often associated with the Yuta/Glove Stealer malware family.
Detects suspicious cross-process memory injection activity by correlating remote virtual memory allocation (VirtualAllocEx or MapViewOfSection) followed by the creation of a remote thread (CreateRemoteThread) targeting established legitimate Windows processes. This behavior is commonly associated with malware loaders such as Payouts King and RomulusLoader for facilitating code injection.
