Researchers detected Kimsuky APT group exploiting the BlueKeep RDP flaw in attacks against South Korea and Japan.
The group gained initial access by exploiting the RDP vulnerability and distributed malware through phishing emails and exploiting the Microsoft Office Equation Editor vulnerability.
They installed MySpy malware and RDPWrap to maintain remote access, and deployed keyloggers to record keystrokes.
Kimsuky APT has been targeting organizations in multiple countries since September 2023, with a focus on South Korea and Japan.
