Hunting PeckBirdy LOLBins Activity
This rule detects potential malware execution and persistence by correlating suspicious script and HTA activity with known malicious infrastructure. It flags mshta, wscript, and cscript executing remote HTA or script content, related network connections and downloads, temporary file artefacts, connections to listed suspicious domains and IPs, attempts to add Windows Defender exclusions, and fake browser update style process launches that retrieve executables over HTTP.
