Microsoft’s PlayReady Security: More Holes Than Swiss Cheese!
Microsoft’s Warbird and PMP security research just got scrutinized by a one-man team. Despite Microsoft’s efforts, the PlayReady content protection was torn apart like a piñata at a sugar-starved kid’s birthday party. The full technical doc is out, revealing Microsoft’s security assumptions were about as secure as a screen door on a submarine.

Hot Take:
Microsoft’s PlayReady security flaws are like a piñata for cyber researchers—easy to crack open, and sadly, no candy inside. Instead, we’ve got a load of unaddressed vulnerabilities and a company that seems to be playing hide and seek with its own bug fixes. Maybe next time they’ll bring more than a “thank you” note to a vulnerability party.
Key Points:
- Security Explorations revealed significant vulnerabilities in Microsoft’s PlayReady for Windows 10 and 11.
- The research highlights major flaws in Microsoft’s code obfuscation and crypto assumptions.
- Security Explorations claims Microsoft hasn’t shown interest in addressing or commercializing the research.
- The disclosure includes a 285MB ZIP file with comprehensive details shared with Microsoft.
- No fixes or mitigations from Microsoft observed in the eight months following initial contact.
