Claim: Windows 11’s built‑in Power Automate RPA can be turned into a persistent C2 and exfiltration channel. It uses Power Automate agents plus an outbound queue (Azure Relay / Service Bus) so payloads and file bytes travel over trusted Microsoft channels, bypassing firewall/EDR detection. A bundled silent registration script enrolls machines (even non‑admin accounts), allows remote job execution, and can run no‑code ransomware built in the drag‑and‑drop actions — and it works on vanilla Windows 11.
