APT39 facilitates lateral movement through myriad tools such as Remote Desktop Protocol (RDP), Secure Shell (SSH), PsExec, RemCom, and xCmdSvc. Custom tools such as REDTRIP, PINKTRIP, and BLUETRIP have also been used to create SOCKS5 proxies between infected hosts. In addition to using RDP for lateral movement, APT39 has used this protocol to maintain persistence in a victim environment. To complete its mission, APT39 typically archives stolen data with compression tools such as WinRAR or 7-Zip
