Detects exfiltration of sensitive information, including Dahua camera credentials and internal identifiers, to the Telegram Bot API over HTTPS. These rules monitor for specific API endpoints (/sendPhoto) and common credential patterns (Login:, Password:, Model:) or indicators (Shodan links, VKontakte references) within HTTP POST requests directed toward api.telegram.org.

This rule detects the creation of XML files matching the 'export_batch_*.xml' naming convention, which is consistent with the output pattern of the Dahua DeviceManager utility. Attackers often use this tool to export camera configuration files containing sensitive credentials (IP, Port, Username, Password). The rule flags activity where multiple such files are created in a short duration, suggesting potential mass exfiltration of camera credentials.

Detects the execution of the rclone utility (including renamed binaries) using command-line arguments consistent with data exfiltration or synchronization (copy, sync, move) that is followed by network communication to known cloud storage providers commonly abused for staging and exfiltration in ransomware attacks.

Detects a high volume of 'MailItemsAccessed' operations within a short 15-minute window performed by a specific application ID. This behavior is often indicative of automated, bulk exfiltration of emails from a Microsoft 365 environment, potentially by a compromised application or an attacker using a malicious OAuth application.

Detects a multi-stage, automated attack chain performed by AI-based development agents (e.g., Claude, Copilot, Cursor). The rule correlates process discovery, credential access, file collection (staging), and exfiltration over web services within a tight 15-minute window, identifying potential autonomous exploitation and data exfiltration. Covered T1046, T1552.001, T1078, T1005, T1567

Detects instances where AI-based coding or agent-driven tools (e.g., Cursor, Claude Code, AutoGPT) perform suspicious file archiving/packaging activities followed by network egress to unauthorized or known exfiltration-prone services. This helps identify potential data exfiltration by AI agents or compromised development environments.
