Analysis Summary
Gootloader, the multi-payload malware platform, is actively targeting entities in the US, Germany, and South Korea. The infection chain begins with social engineering techniques that include manipulated search engine optimization (SEO), which brings malicious websites to the top of the results on search engine websites. This fraudulent forum website includes a link that, when clicked, initiates the download of a JavaScript file and then begins the next stages of the attack. Using fileless techniques, the malicious activity can remain undetected by the user and allow the download of additional malware, including the Kronos malware, Cobalt Strike exploitation tool, the Gootkit trojan, or Sodinokibi ransomware.
