Detects HTTP responses and requests involving exposed Claude Code open directories (.claude/CLAUDE.md) tied to ARTEX operator infrastructure.
Detects HTTP responses and TLS client connections associated with Adobe-themed device code phishing lure pages hosted on workers.dev, utilizing specific patterns and keywords such as 'Confirm to open document', 'VERIFICATION CODE', and long hyphenated domain structures.
This rule monitors for known malicious file hashes, command and control (C2) domains, and specific download URLs associated with identified threats. It correlates these indicators across process execution, file activity, and network connection logs to identify potential compromises or malicious activity related to the aware-cr1 infrastructure.
This rule detects indicator of compromise (IOC) sweep events associated with the AhsayCBS campaign (CVE-2026-105133 and CVE-2026-105134) involving XMRig cryptominer activity. It checks for specific file and process SHA256 hashes, remote IP addresses, and domain connections related to known mining pools or attacker infrastructure using Sentinel Device tables.
Detects HTTP, TLS, DNS, and TCP communication with known AhsayCBS campaign infrastructure and Alibaba OSS storage buckets used for payload delivery.
Detects an unauthenticated remote code execution attempt against AhsayCBS via the UpdateReceivers.do endpoint using the checkSysPwd parameter, associated with CVE-2026-105133 and CVE-2026-105134.
Detects anomalous process execution and loopback network activity associated with the Model Context Protocol (MCP) 'exec_in_session' method. This pattern indicates an adversary potentially abusing the AI coding assistant's MCP server capabilities to execute arbitrary commands as a C2 channel.
Detects DNS lookups, TLS connections, and network traffic associated with the PoeLLM cryptominer communicating with Kryptex mining pools, as well as Stratum mining protocol login attempts.
Detects an exploitation attempt against PoeLLM or LiteLLM MCP test/connection endpoint using a python3 stdio payload that fetches data from port 81.
Detects potential exploitation attempts targeting unpatched Citrix NetScaler ADC or Gateway devices, specifically looking for unauthenticated requests to management or sensitive endpoints that contain command execution indicators. This rule is designed to identify activity associated with vulnerabilities similar to CVE-2026-88771.
