Researcher demonstrates timestamp forgery in C2PA content credentials
Original: How to hack time, with C2PA
Security researcher David Buchanan, known online as Retr0id, has published a write-up describing how C2PA content provenance metadata, which records when and how digital media was created, can be manipulated to produce misleading timestamps. The post outlines practical attacks on the time component of the standard, raising questions about how reliably C2PA credentials can prove authenticity of photos and videos.
Why now: New research shows a weakness in the C2PA authenticity standard that tech and security communities rely on for media provenance.
