VERY IMPORTANT

A sophisticated multi-stage malware campaign employs living-off-the-land techniques and in-memory payload delivery to evade security controls. The infection chain begins with a hidden batch file that executes an embedded PowerShell loader, which then injects Donut-generated shellcode into legitimate Windows processes. The final payload is a heavily obfuscated .NET framework implementing advanced anti-analysis techniques, credential harvesting, surveillance capabilities, and remote system control. Data exfiltration occurs via Discord webhooks and Telegram bots. The malware, identified as Pulsar RAT, features live chat functionality and background payload deployment, demonstrating a modern, high-evasion Windows malware operation designed for long-term access and large-scale data theft.
