README
With this responder you can
- Isolate machine
- Unisolate machine
- Run full antivirus scan
- Push IoC to Microsoft defender
- Alert
- BlockAndAlert
- (future: Collect investigation package)
NOTE: Microsft API for finding machines via IP-addresses is little bit limited "Find Machines seen with the requested internal IP in the time range of 15 minutes prior and after a given timestamp.", because of this "hostname" is preferable observable type"
Responder needs one of the following licenses:
- Windows 10 Enterprise E5
- Microsoft 365 E5 (M365 E5) which includes Windows 10 Enterprise E5
- Microsoft 365 E5 Security
