How do I remediate zhgjin3740c2 if I installed it?

zhgjin3740c2 establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed zhgjin3740c2 — how do I know if it already compromised me?
