The malware employs a multi-stage attack process involving batch files, PowerShell scripts, and VBScript to exfiltrate sensitive data and maintain persistence. The attack begins with a zip archive containing a malicious LNK file disguised as a document. The malware exploits Windows Explorer limitations to hide malicious commands and uses obfuscation techniques to evade detection. Key capabilities include data exfiltration from user directories, system information gathering, persistence through registry modifications, and communication with command-and-control servers. The report includes detailed technical analysis of the attack stages, from initial infection to data exfiltration, along with indicators of compromise and YARA detection rules.</p><p><a href="https://swecyb.com/tags/Cybersecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Cybersecurity</span></a> <a href="https://swecyb.com/tags/NorthKorea" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NorthKorea</span></a> <a href="https://swecyb.com/tags/APT37" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>APT37</span></a> <a href="https://swecyb.com/tags/MalwareAnalysis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MalwareAnalysis</span></a> <a href="https://swecyb.com/tags/ThreatIntel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ThreatIntel</span></a> <a href="https://swecyb.com/tags/Malware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Malware</span></a> <a href="https://swecyb.com/tags/Reversing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Reversing</span></a></p>
