This rule detects instances of 'javaw.exe' executing from unusual directories (e.g., AppData, Temp, Users\Public) while loading a 'jli.dll' file from a related non-standard path, or simultaneously being associated with a scheduled task execution involving 'GlobalTellurSync'. This behavior is indicative of potential DLL side-loading or a persistence mechanism where a legitimate Java executable is repurposed to run malicious code.
Detects a specific persistence chain attributed to DragonForce where the 'javaw.exe' process side-loads a malicious 'jli.dll' from a non-standard, user-writable directory. The rule correlates this DLL image load with the subsequent reading of an encrypted, host-bound payload file ('rvsdiqw.txt') by the same process, which is then decrypted and injected into memory.

This rule detects anomalous GET requests to PHP files within the WordPress themes directory that match the specific pattern used by the DragonForce threat actor for secondary C2 beaconing. The detection identifies requests that lack typical WordPress request indicators like cookies or specific form fields, suggesting non-browser, programmatically generated C2 traffic.

Detects anomalous execution of PowerShell commands spawned by processes identified as 'javaw.exe' or 'GlobalTellurSync.exe' (associated with DragonForce backdoor activity). The detection focuses on instances where these processes launch from non-standard user-writable directories (e.g., AppData, Temp) and execute PowerShell commands that contain obfuscated arguments or payloads, while excluding standard scheduled task invocations.

The detection focuses on instances where these processes launch from non-standard user-writable directories (e.g., AppData, Temp) and execute PowerShell commands that contain obfuscated arguments or payloads, while excluding standard scheduled task invocations.
Detects network activity associated with the DragonForce backdoor, specifically the use of MQTT for command and control. The rules monitor for unique 16-character client IDs used during registration on non-standard ports, subsequent command retrieval structures containing 'cmdnum', and DNS queries for the hardcoded broker 'broker.emqx.io'.
