This file, , is a compressed archive frequently associated with GootLoader malware infections . It typically contains a malicious JavaScript (.js) file disguised as a legitimate document (often related to legal, business, or medical topics) to trick users into executing it. File Overview File Name : 02279.7z
: If this file was executed, disconnect the machine from the network immediately.
: Perform a deep scan using an EDR (Endpoint Detection and Response) tool to identify registry-based persistence.
: The user extracts the .7z file and double-clicks the .js file, believing it is a document.
: Once executed via wscript.exe , the script reaches out to a Command and Control (C2) server to download the next stage, which often includes Cobalt Strike or fileless malware that resides in the registry. Technical Indicators Parent Process : explorer.exe or 7zFM.exe (extraction). Active Process : wscript.exe (executing the script).
: The JavaScript uses heavy obfuscation (junk code, reversed strings, and large arrays) to bypass signature-based antivirus detection.
: GootLoader often creates a scheduled task or a registry key in HKCU\Software\ to maintain access after a reboot. Recommended Actions
: Usually a JavaScript file with a long, SEO-optimized name (e.g., contract_agreement_8234.js ).
