  • Ensure you have collected all of the information you need before rebooting. With MalwareBytes installed, it's going to want to reboot. You may want to install a few other packages before rebooting, however. If you had a problem with System Restore or VSS restoration of files, then check out the Arsenal Recon Image Mounter (it is especially important to try this because ransomware may actually go after the restore points and VSS itself, disabling them). Another great thing to do before rebooting is to perform a P2V virtual-machine guest clone operation, usually with VMware vCenter Converter. Because you'll also likely be connecting back to the global Internet after reboot, also ensure that you will be able to update to the OS-level and app-level patches. You may want to check out the free trial of Corporate Software Inspector from Flexera (formerly Secunia) if you have nothing else. Another favorite is the Microsoft Baseline Security Analyzer (MBSA) program. Check a few settings such as the Windows Firewall or the macOS Security & Privacy section of System Preferences. If you want to see a large list of security settings, be sure to check out the free tool, Airlock, from Lunarline (N.B., it only works with Windows OS versions 7, 8, and 8.1 and will only apply security settings to Internet Explorer versions 8, 9, and 10 -- but this tool is fantastic in a secure-configuration regard). Ensure that network shares will not attach/remap when the computer restarts. You can check these in WindowsWindows and in macOSmacOS.
  • Restore; Restore; Restore. The last thing to do before reboot is to check the AutoRuns. For Windows, this means run Autoruns (again, try to get it via USB or lab/recovery network instead of the global Internet). Try to review each item with an expert. In macOS, to review the items that will run at startup, go into System Preferences, Users & Groups, and Login Items. Restore by restarting and paying attention to MalwareBytes if it prompts you. Restore by running MalwareBytes again. Restore by getting approval to connect back to the global Internet. Update MalwareBytes. Run MalwareBytes again. Update your OS and run any built-in or third-party OS-level and app-level update programs. Restore by letting the updates complete and rebooting if they prompt you to. It is now safe to copy the files you restored from backup and overwrite the encrypted files. Ensure that you have restored all service/data to the the state it was prior to the incident ocurring.
  • Use the computer. Is it ok? Is everything back to normal? It is ok to kill processes or stop services that you deem still scary-looking. If files were missing or could not be located from backups, then what is the next recourse? My suggestion is to copy all of the still-encrypted files to offline storage, such as a USB drive. Perhaps at a later time a recovery utility will be built for the ransomware files. Does the computer act as if it has any malware (not just ransomware) still? If so, then quarantine it and escalate research, expertise, and DFIR capabilities.
  • Be willing to use a different computer even if it appears ok. Be willing to hand over your computer to an expert. Be willing to allow it to sit in quarantine longer. Be aware and prepared that during the next-and-last phase, you could never see this particular computer ever again.
