A teenager named Peter Stokes is facing federal charges in Chicago for allegedly hacking a U.S. jewelry retailer while using a VPN to conceal his online activities. Microsoft provided the FBI with data linked to a tracking mechanism called the Global Device Identifier (GDID), which is a unique number assigned to every Windows installation that persists through updates. This identifier allowed authorities to connect Stokes' computer to specific websites, despite his VPN usage. Stokes was arrested in Helsinki in April 2026 while trying to board a flight to Japan, carrying two two-terabyte hard drives. The GDID enabled Microsoft to track Stokes' activities on third-party services, raising concerns about privacy and data tracking.
