A 19-year-old named Peter Stokes was detained at Helsinki airport in April 2026 while traveling to Japan, carrying two 2TB hard drives. He was subject to an Interpol Red Notice and faced a federal complaint from U.S. prosecutors by July for his alleged involvement in the Scattered Spider hacking group, which breached a U.S. luxury jewelry retailer in May 2025, leading to a ransom demand. The Global Device Identifier (GDID), developed by Microsoft, is a persistent identifier that uniquely identifies a Windows installation on a device. It links online activities back to a single identity, which law enforcement can use to trace a device's owner. The GDID is generated when a user signs into Windows with a Microsoft Account and remains through updates but does not survive a clean reinstall. Stokes' use of the same Windows device allowed investigators to trace his activities through the GDID, which linked him to the hacking incident. Privacy advocates have raised concerns about the lack of consent for GDID assignment and the potential for surveillance.
