The attack chain begins with a batch script establishing persistence via Registry Run keys, then uses a PowerShell loader to inject .NET shellcode directly into memory. The malware supports live, interactive operator control for real-time reconnaissance and command execution, while simultaneously harvesting credentials and system data. It employs anti-analysis techniques including anti-VM and anti-debugging measures, and exfiltrates stolen data through Discord webhooks and Telegram bots. Detection requires behavioral monitoring of PowerShell execution, shellcode injection, and Registry modifications rather than traditional file-based scanning. ## Full article daily.dev links to this article rather than hosting it.
