Detects outbound HTTP POST requests to known public Ethereum RPC gateways (Alchemy and Infura) containing embedded, hardcoded API keys or references to specific contract addresses associated with the 'indexed-btree' malware campaign. This pattern indicates a compromised host leveraging legitimate Web3 infrastructure for Command and Control (C2) communication.

This rule detects the creation of a scheduled task via schtasks.exe that uses a name similar to 'Google Chrome Update' but is initiated by a process other than the legitimate Google Update executable or from an unexpected folder location. This behavior is commonly used by adversaries to establish persistence while masquerading as legitimate software update mechanisms.

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 identifies successful network connections from local devices to a predefined list of known malicious IP addresses within the last 7 days. Such connections often indicate active communication between a compromised endpoint and adversary-controlled infrastructure.

Detects successful API requests to sensitive administrative endpoints on WSO2 systems that lack a corresponding legitimate authentication event (session) from the same SourceIP and user pair, which may indicate the use of forged JWTs or authentication bypass exploitation (e.g., CVE-2026-5430).

Detects activity associated with the 'MovieReaper' threat campaign by identifying known malicious file hashes, command and control (C2) IP addresses, and communication with identified malicious domains. This rule monitors process execution, file operations, and network connections within the campaign's active timeframe.

Detects anomalous access to WSO2 API Manager Store and Publisher endpoints involving the retrieval of sensitive information like consumer keys and secrets. The rule specifically targets requests authenticated with JWTs that exhibit headers indicative of 'alg=none' or other unsupported/forged algorithm patterns, often associated with CVE-2026-5430 exploitation attempts. The rule uses statistical baseline monitoring to identify volume spikes in requests to these sensitive paths.
