Description
This article demonstrates how to circumvent anti-analysis techniques employed by GootLoader malware while utilizing Node.js debugging in Visual Studio Code. GootLoader JavaScript files employ an evasion technique that can pose a formidable challenge for sandboxes attempting to analyze the malware. The malware creators leveraged time-consuming loops with arrays of functions to deliberately delay the execution of malicious code, effectively implementing a sleep period to obfuscate GootLoader's malicious nature. Through continuous collaboration and knowledge sharing, we can enhance our ability to detect, analyze, and develop effective countermeasures against such malicious software.
