TWINLOOT Python Implant Uses SharePoint/Teams for C2
- Engineer — Learn: No exploitation signals or patch action required, but this technique highlights the risk of trusting M365 egress unconditionally; review whether SharePoint/Teams API access from non-user contexts is logged and anomaly-monitored in your environment.
- SOC/IR — Plan: TWINLOOT’s C2-over-SharePoint-Online pattern blends into legitimate M365 traffic — build or tune detections for unusual SharePoint file polling cadence and Teams API calls from non-interactive service contexts to catch implants using this framework.
- Leader — Learn: Newly documented implant class that weaponizes trusted M365 services, useful context for future conversations about M365 security controls and monitoring investment, but no confirmed active campaigns require immediate leadership action.
