How do I remediate wprox-c217-1mod if I installed it?

wprox-c217-1mod 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 wprox-c217-1mod — how do I know if it already compromised me?

If wprox-c217-1mod was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
