Detects instances where rundll32.exe is executed by a process named 'eld0.exe' residing in user-writable or temporary directories (e.g., Users, ProgramData, Temp, AppData). This behavior is characteristic of execution flow hijacking or malicious payload loading from suspicious file paths.
This rule detects attempts to exploit the LiteLLM proxy pass-through endpoint to interact with the cloud Instance Metadata Service (IMDS). Specifically, it identifies configuration attempts to route traffic to the IMDS IP (169.254.169.254) and subsequent requests to retrieve IAM security credentials, which is indicative of a Server-Side Request Forgery (SSRF) attack to steal cloud identity tokens.
Detects successful authentication attempts to a LiteLLM proxy instance using the hardcoded default master key 'sk-1234'. This activity indicates potential exploitation of misconfigured instances where default credentials remain unchanged.

Detects instances where LiteLLM, or related Python application processes (uvicorn, python), spawn a shell or command-line utility (bash, sh, id) under the root user account. This behavior is indicative of potential container breakout, application exploitation, or privilege escalation attempts originating from a web-accessible service.
Detects DNS queries and TLS SNI traffic directed towards known phishing domains that mimic Brazilian financial and government portals, specifically targeting 'gerenciadorcaixa.digital', 'aapj.digital', and 'receitafederal.digital'.
Detects NSIS installer/archive contents bundling the specific unsigned/renamed UpdateAssistant.exe (aka AppUpdateHelper.exe) payload alongside its associated staged runtime DLLs and known malicious file paths/hashes used as cover noise for DLL sideloading staging

Detects an HTTP GET request to 'dl.php' containing an 'f' parameter (target file) and an 'k' parameter (access token), followed by a response body starting with the 'MZ' header, indicating the successful download of a Windows PE executable as part of a potential phishing campaign stage-2 payload delivery.
