Identifies devices with Signal software flagged by Defender Vulnerability Management for CVE-2026-113380 (RingRTC before 2.72.0, hangup commands dropped when call state machine queue is flooded). Exposure rule, not an exploit detection; results are deduplicated per device and sorted by recent Signal activity.
Detects instances of GitLab and Ruby running vulnerable software versions based on software inventory checks against fixed release versions.
Detects command output staged in a temporary file (/tmp/nx_cmd.txt) by a Unix shell spawned from ExifTool or Perl, typically resulting from Gotenberg CVE-2026-42589 exploitation, or detects the specific staging filename behavior independently.
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 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.
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.
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.
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.
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 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.

Results are summarized per device and IOC.
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 endpoint network connections made to known staging IP addresses often associated with data exfiltration or staging activities.
Detects Tailscale serve commands setting up a TCP forward to a Unix socket (such as tailscaled.sock), correlated with recent file creation, modification, or renaming events involving the socket file by a non-standard process within a 1-hour window.
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 network, DNS, email, and URL click events matching known IOC domains associated with AdFection, Candiru, and Discover-Tech threat intelligence reports.
Detects endpoint execution of specific known brute-force scripts and tools (such as ssh_brute.py, brute3.py, auto_login.py, etc.) using Python or shell interpreters, correlated with a high outbound network connection fan-out (50 or more distinct target IPs) from the same process.
