Detects outdated or vulnerable installations of GitLab and Ruby across devices using TVM software inventory, software vulnerabilities, process events, and file events, checking against known fixed versions for specific CVEs.
Detects the execution of Microsoft Quick Assist followed by a different remote access tool (RAT) or remote monitoring and management (RMM) utility on the same device within a 24-hour window, which may indicate adversary staging or persistence establishment.
Detects a sequence where a Codex agent process executes a shell or command interpreter, followed by logging or monitoring tampering activity on the same device within a 30-minute window.
Detects execution of BlackX UEFI bootkit installer components, renamed helper binaries acting as payloads (such as jcef_helper.exe renamed to googleupdate.exe), or known malicious file hashes associated with BlackX campaigns.
Detects potential local privilege escalation (LPE) attempts leveraging the afd.sys vulnerability by correlating LPEClient or FudModule artifact creation, image loads, or process execution with subsequent afd.sys driver loading or exploit guard blocking events within a 60-minute window.
Detects the presence of the OrbitalVoyage payload package or related artifact names in device file and process telemetry, including suspicious APK installations outside of authorized paths.
Detects the execution of unapproved Remote Monitoring and Management (RMM) software tools followed by subsequent outbound public IP network activity from the same process on the same device, indicating an active remote session.
Detects abnormal PHP execution volume storms, process crashes handled by crash reporters (such as werfault.exe, apport, systemd-coredump), or application error events related to PHP, which may indicate denial of service attacks, exploitation attempts, or severe application instability.
Detects a sequence where a device runs a staging/archiving utility (such as WinRAR, 7-Zip, or a copy script) followed within 4 hours by a file transfer or synchronization tool (such as rclone or FileZilla), which is indicative of data staging prior to exfiltration.
Detects the correlation of remote execution tools (such as PsExec, WinRM, or specific PowerShell remote execution commands) with RDP or ScreenConnect remote management activity on the same device within a one-hour window, potentially indicating lateral movement or unauthorized remote control.
Detects potential tampering of Apache HTTP Server configuration files (httpd.conf) involving PHP engine or script handlers, followed closely by an Apache service reload (HUP signal) on the same device within a 10-minute window.
Detects potential abuse of Tailscale SSH Unix socket forwarding where the tailscaled daemon touches sensitive files/sockets (such as docker.sock or /etc/shadow) or creates/replaces Unix sockets following an SSH session.
The following analytic identifies instances where the regsvr32.exe binary has been renamed and executed. This detection leverages Endpoint Detection and Response (EDR) data, specifically focusing on the original filename metadata. Renaming regsvr32.exe is significant as it can be an evasion technique used by attackers to bypass security controls. If confirmed malicious, this activity could allow an attacker to execute arbitrary DLLs, potentially leading to code execution, privilege escalation, or persistence within the environment.
Detects abnormal PHP execution volume storms, process crashes handled by crash reporters (such as werfault.exe, apport, systemd-coredump), or application error events related to PHP, which may indicate denial of service attacks, exploitation attempts, or severe application instability.
Detects registry-based User Account Control (UAC) bypass activity where command keys for ms-settings or mscfile are created or modified under HKCU Software\Classes, correlated with a privilege adjustment (SeDebugPrivilege or SeLoadDriverPrivilege) by the same process within a 30-minute window.
Detects the presence of Cisco SD-WAN vManage software, vulnerabilities related to CVE-2026-76504, associated file artifacts, and process executions across endpoints using inventory and event logs.
Detects NTDSUtil commands associated with Active Directory database export, installation media preparation, and snapshot creation, which may facilitate offline credential extraction.
Detects execution of BlackX UEFI bootkit installer components, renamed helper binaries acting as payloads (such as jcef_helper.exe renamed to googleupdate.exe), or known malicious file hashes associated with BlackX campaigns.
Detects potential abuse of Tailscale SSH Unix socket forwarding where the tailscaled daemon touches sensitive files/sockets (such as docker.sock or /etc/shadow) or creates/replaces Unix sockets following an SSH session.
Detects host-side telemetry indicating Cairn agent worker artifacts, including specific process command line terms, tsec skill files and environment variables, combined with network connections to OpenRouter from the same host.
Detects the modification or setting of the execInstalledOnly parameter to false, 0, or disabled on VMware ESXi or Linux hosts via process execution command lines or syslog messages, often associated with running uninstalled or arbitrary scripts/binaries in virtualized environments.
