LuoYu actor drops WinDealer
Kaspersky followed on the findings by TeamT5 to discover that WinDealer—deployed by Chinese-speaking threat actor LuoYu—has been performing intrusions through a man-on-the-side attack. This technique allows an actor to modify in-transit network traffic and insert malicious payloads. What makes this especially dangerous is that it requires no interaction with the victim.
