The tool works by setting up a local, emulated Key Management Service server on the host machine. Microsoft legitimately uses KMS in corporate enterprise environments to let thousands of computers activate under a single local server rather than connecting individually to Microsoft's global activation infrastructure. AAct tricks the local operating system into believing it is part of a corporate network, using system hooks, WinDivert drivers, or TAP network adapters to force a successful local validation. Why Is It Shared as a ".zip" File?

AAct creates a local service. However, if the binary is compromised, it could be "phoning home" to a command-and-control server. Legitimate activators generally do not require an active internet connection (they emulate the server locally), so network activity during activation is a red flag.
