Detects Rust-compiled executables exhibiting C2-capable characteristics consistent with backdoors dropped on compromised JFrog Artifactory servers

This rule detects the creation of a .groovy file within a plugin directory related to JFrog Artifactory, followed by the execution of suspicious child processes (e.g., shell, curl, wget) by the Artifactory process within a short timeframe. This behavior is indicative of an attacker attempting to achieve remote code execution by deploying a malicious plugin.
Detects the suspicious execution of cmd.exe with piped stdio handles (indicative of a reverse shell) initiated by non-standard parent processes associated with the GRAYRABBIT malware, correlated with an immediate outbound network connection from the same process.

Detects the execution of an unsigned 7z.exe that loads an unsigned 7z.dll from a public, user-writable directory (C:\Users\Public\Documents). The rule specifically looks for the creation of the DLL shortly before it is loaded, indicating potential DLL side-loading to bypass security controls using a renamed or modified archive utility.

Detects incoming HTTP POST requests to the GitLab '/import' endpoint that attempt to access the internal cloud metadata service (169.254.169.254), indicating an exploitation attempt for vulnerabilities such as CVE-2021-22175 or CVE-2021-39935.
