We prototyped a Windows Installer Package Canary to help detect certain first stage trade craft. The ultimate goal being to alert for those threat actors targeting security products through uninstallation.
We prototyped a Windows Service Canary to help detect and respond to certain pre-ransomware trade craft. The ultimate goal being to alert and minimize the impact of ransomware deployments.
