Mysterious Elephant

sigil · no ATT&CK coverage stated

Analyst brief

misp-galaxy

Mysterious Elephant is an APT group active since 2023 that primarily targets government and foreign affairs entities across South Asia, especially Pakistan, Bangladesh, Sri Lanka, Nepal, and Afghanistan. In its early-2025 campaign it shifted toward spear-phishing and custom/customized tools—including the BabShell reverse shell and MemLoader HidenDesk/Edge loaders—to deploy RATs like Remcos and VRat, while also using WhatsApp-specific exfiltration tools to steal shared documents, images, and archives. The group shares code and infrastructure with other APT clusters (Origami Elephant, Confucius, SideWinder), reflecting ongoing tool reuse and collaboration among South Asian threat actors.
