Detects HTTP POST requests to the Telegram Bot API (/sendPhoto) containing structured string patterns typical of exfiltrated Dahua camera credentials, including login, password, port, location, and channel information. This indicates an automated exfiltration attempt where stolen device credentials are sent to an adversary-controlled Telegram bot.

Detects network beaconing activity associated with Transparent Tribe (APT36) Golang-based remote access trojans (RAT). The rule identifies specific HTTP POST requests to suspicious domains and URI paths ('/api/gym-facility', '/api/gym-membership') that mimic legitimate fitness-related traffic to blend in with environment noise.

Detects network communication patterns associated with the RUSTYSHADE malware family, which leverages the GitHub REST API for command-and-control (C2) operations. The rule monitors for specific SNI indicators, GitHub API URL patterns for command retrieval, task/result file interactions, exfiltration of files (screenshots/webcam photos), and custom encrypted request body markers.

Detects execution of processes associated with QuasarRAT or references to its configuration files, originating from or involving files and processes named 'UBPUpdater.exe' or 'UBPPatch.Psh'. Also identifies network connections via FTP or involving configuration files ('config.Ini') initiated by these specific processes, which may indicate malicious activity, command and control, or data exfiltration.

Detects network connections originating from browser processes to known JeetBot command and control (C2) infrastructure. The rule identifies suspicious C2 communication and, specifically, attempts at token exfiltration by monitoring for auth tokens in the URL of requests directed to known JeetBot hosts and Twitch-related infrastructure.

Detects potential data exfiltration activity where a host is communicating with the Telegram Bot API. The rule identifies high-frequency connections to api.telegram.org and inspects HTTP URIs for signs of Telegram Bot token usage combined with 'sendDocument' or 'sendPhoto' commands, which are common indicators of malicious exfiltration.

Detects outbound network traffic associated with the Tailscale VPN protocol, specifically identifying potential unauthorized or personal tailnet communication channels. The detection monitors for TLS SNI strings ending in '.ts.net' and WireGuard handshakes on UDP port 41641. These indicators are common to all Tailscale client activity and require environment-specific exclusions of sanctioned Tailscale infrastructure to minimize noise.

Detects high-frequency, automated interactions with popular AI assistant web interfaces (e.g., Gemini, Perplexity, Claude, Copilot) from common browser processes. This pattern often indicates unauthorized automated data submission or scraping, which may follow or facilitate automated exfiltration of browser-resident data.
