Detects unauthorized processes reading, copying, or renaming Kerberos ticket cache files (ccache) located in common temporary directories. This behavior is often associated with credential theft and potential Pass the Ticket attacks where adversaries attempt to extract session credentials to perform lateral movement or privilege escalation.

Detects execution of macOS.Gaslight malware by identifying specific function calls within process command lines, specifically 'SecTrustSetAnchorCertificatesOnly' for certificate pinning, 'SCDynamicStoreCopyProxies' for proxy awareness, and 'CCRandomGenerateBytes' for cryptographical operations. These behaviors are typical of the implant's efforts to maintain encrypted C2 communication while frustrating network inspection tools.

This rule detects potential data exfiltration attempts by monitoring for network connections to URLs containing suspicious substrings (bit, onion, .cc, .su) over common web and DNS ports (53, 80, 443, 8080). It flags high-frequency unique connection attempts from a single device, which may indicate command-and-control (C2) traffic or data exfiltration over covert channels.

204
Detects the execution of processes with command-line arguments containing keywords related to known supply chain attacks (e.g., solarwinds, 3cx, kaseya, npm, pypi). This rule is intended for threat hunting to identify potential exploitation attempts or malicious activity involving software supply chain components.

This rule detects activities associated with a specific malicious browser extension, including the presence of its files on disk, execution of browsers with the extension ID in the command line, and network connections to known malicious or typosquatted domains (perplexity-ai.online, extension.tilda.ws) used for C2 or exfiltration.

Detects DNS queries to known StegoAd command-and-control domains 'liveupdt.com' and 'dealctr.com'. These domains are used by the StegoAd campaign to deliver steganographic payloads and push malicious JavaScript to compromised browser extensions.

Detects the creation of persistence mechanisms, specifically cron jobs or LaunchAgent plist files, initiated by the OpenClaw agent process tree (openclaw, openclaw-runtime, openclaw-agent). This behavior is associated with ClawHub skills attempting to maintain C2 access after the skill itself has been removed.

Detects the installation of Visual Studio Code extensions from sources other than the official Marketplace. This activity is monitored by checking process command line arguments for the --install-extension flag combined with external URLs or local file paths, which may indicate an attempt to install malicious extensions.

Detects unauthorized execution of node.exe by the Flowise process, where a case-insensitive environment variable (node_options) is used to bypass Flowise's security block list. This enables attackers to leverage the --require flag to preload malicious JavaScript code. The detection also monitors for the presence of a 'flowise_marker.txt' file as a secondary indicator.

This rule detects outbound network connections to the typosquatted domain 'perplexity-ai.online'. This domain is associated with a malicious Chromium extension masquerading as a 'Search for Perplexity AI' tool, which uses this domain for search-traffic interception and command-and-control (C2) exfiltration.

Detects outbound SSH connections from common applications using libssh2 to external, non-standard or untrusted servers, followed by an anomalously large inbound TCP data transfer before authentication completes. This behavior is indicative of exploitation attempts targeting CVE-2026-55200, where a malicious SSH server triggers a heap overflow in the client via a malformed packet.

Detects network connections to known command and control (C2) infrastructure associated with malicious NPM packages acting as Remote Access Trojans (RATs). The rule identifies specific outbound connections to a hardcoded malicious IP and port, as well as traffic involving a suspicious domain string.

Detects indicators of active exploitation or malicious activity targeting the Flowise application. The rule triggers on the creation of a 'flowise_marker.txt' file, the spawning of node processes with suspicious command-line flags ('--require', 'node_options') potentially intended to bypass security controls, and the execution of unexpected shell or scripting processes (cmd, bash, python, etc.) by a Flowise process.
