Detection & response playbook

Backdoor / remote access
  1. Find it

    Search your lockfiles and build artifacts for wprox-c217-2git (version 0.0.1).

  2. If you installed it — respond

    wprox-c217-2git 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.

  3. Did it already run?

    If wprox-c217-2git 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.
