MgBot backdoor delivery and injection via secondary loader
Malware Activity
Summary
Hide ▲
Show ▼
The MgBot backdoor was delivered through a secondary loader and injected into svchost.exe, giving operators a stealthy foothold on infected systems. The payload supports credential theft, keystroke logging, clipboard capture, and audio recording. That behavior makes the malware suitable for long-term espionage and silent data collection. The delivery chain also used sideloading and encrypted staging to reduce detection.
