Detects a process that has established a connection to the Telegram Bot API subsequently performing a large volume of file deletions across multiple folders within a 15-minute window. This behavior is indicative of a remote-controlled destructive attack, such as the deployment of a wiper malware (e.g., HEAVYGRAM or CHOSEN BRICK) triggered via Telegram C2 commands.
Detects the initialization of known-malicious Terraform providers (dockerd) followed within one hour by the execution of a 'go run' process from the .terraform directory. This pattern is indicative of a supply chain compromise where an adversary leverages a typosquatted or malicious Terraform provider to facilitate the execution of a secondary payload.

This rule detects a correlation between host-level reconnaissance activity using WMI (via PowerShell or WMIC) to query system information, followed by network exfiltration to a known C2 IP address over a specific URI within a 10-minute window.
This rule monitors endpoint telemetry (File, Process, and Network events) to identify activity associated with a pre-defined set of known malicious file hashes, IP addresses, and domains. It correlates these indicators to detect potential malware execution, persistence, or command-and-control communication on monitored devices.

Detects potential exploitation of CVE-2025-3248 in Langflow by identifying suspicious inbound network traffic targeting the /api/v1/validate/code endpoint, correlated with subsequent python child processes containing base64 decoding and execution primitives such as eval, exec, or subprocess.
This rule identifies instances of Cisco Secure Email Gateway (AsyncOS) running vulnerable versions that are susceptible to CVE-2026-76461. It parses the software inventory data to identify appliances within branches 15.5, 16.0, and 16.5, comparing the patch and build versions against the known secure release versions (15.5.5-0141, 16.0.4-302, 16.5.0-780).
Detects network communication associated with the Casbaneiro (Metamorfo) banking trojan, specifically identifying DNS queries, TLS SNI headers, HTTP Host headers, and direct IP connections to known malicious C2 infrastructure.
Detects execution of the MovieReaper initial loader binary. This malware employs advanced anti-analysis techniques, specifically manual PEB-walking to resolve APIs and evade detection by standard library loading hooks. The rule alerts on known file hashes and specific masquerading filenames.
