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 Tailscale (tailscaled) reaching out to cloud instance metadata endpoints or Kubernetes internal service APIs, which may indicate unauthorized access or abuse of app connectors.
Detects a VS Code-family editor or extension host process running 'git config --global user.email' and, within one minute from the same parent process, a curl public-IP lookup (ifconfig.me / api.ipify.org), the host-profiling step of the trojanized anthropic.claude-code loader.
Detects a VS Code-family editor or extension host process running 'git config --global user.email' and, within one minute from the same parent process, a curl public-IP lookup (ifconfig.me / api.ipify.org), the host-profiling step of the trojanized anthropic.claude-code loader.

Detects a VS Code-family editor or extension host modifying ~/.ssh/authorized_keys, or shell commands appending the svc-telemetry label / embedded Ed25519 key, as used by the trojanized anthropic.claude-code extension.

Alerts whenever a default SAP administrative account (e.g., SAP*, DDIC, TMSADM) logs into the system. These accounts should be locked and used only for emergency 'break-glass' scenarios
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 a web server process (apache2, httpd, php-fpm) spawning a Unix shell (dash/sh) that executes discovery commands such as id, whoami, hostname, or find. This is the durable post-exploitation signature of the wp2shell WordPress pre-auth RCE chain (CVE-2026-63030, CVE-2026-60137), where a malicious plugin or webshell executes commands through the web stack.
Detects repeated Ollama warning-level network errors, such as DNS lookup failures, TCP connection issues, or host resolution problems. These events can indicate a connectivity issue and warrant investigation, but do not by themselves establish unauthorized access or reconnaissance.
Sweeps endpoint telemetry for known IOCs from the trojanized anthropic.claude-code (Open-VSX v2.1.313) SSH backdoor: C2 IP 134.209.82.225, beacon URL, extension.js and tunnel key SHA-256 hashes, and ifconfig.me lookups from VS Code-family/extension-host processes. Results are summarized per device and IOC.

Detects suspicious command execution activities using Azure RunCommand, Custom Script Extension, or Azure Connected Machine Agent combined with potentially malicious command arguments or tools such as PowerShell encoded commands, 'IEX', download strings, certutil, whoami, base64, curl, or wget.
Detects execution of Node.js and NPM related commands involving potential supply chain indicators, script execution, or download utilities (such as curl, wget, powershell, or eval) within command lines.
Detects a sequence of events on a Linux device where a sudo command execution is followed within 15 minutes by a Perl process executing base64 decoding commands within the same SSH session.
Detects an AhsayCBS / Tomcat / Java web service process spawning a
command or script interpreter. After exploiting AhsayCBS, attackers executed
shell commands through the dropped webshell to run reconnaissance and download
the XMRig payload. A backup web service should never directly spawn cmd.exe,
powershell.exe, or a Unix shell - this indicates webshell command execution.

Detects repeated crashes of GitLab Ruby, Puma, Sidekiq, or bundle processes on Linux within a short time window. The detection looks for crash markers such as segfault, SIGSEGV, SIGABRT, or onigmo in the command line, which typically indicate exploitation attempts against Onigmo regex engine vulnerabilities.
