  • Isolate the compromised systems from your network, and unplug any network cables and/or disable wireless access, without turning the systems off
  • Keep all logs and other electronic evidence of what’s happened
  • Back up your systems to preserve their current state, which will help with any investigations
  • Take note of all the actions you take in the process
  • Make sure you get advice from us before you process any more transactions
