Media, Content & DRM

Broadcasters, streaming platforms, rights holders, social networks

Your premium content. Available on torrents within the hour.

Widevine L3 bypassed, PlayReady circumvented. DRM is the last line between billions in rights investments and industrial-scale piracy. Quarkslab audits the systems that hold that line — and protects the code of those who deploy them.

THE PROTECTION OF CONTENT IN THE FACE OF INCREASINGLY INDUSTRIALIZED PIRACY

Widevine, PlayReady, FairPlay: DRM is not inviolable
Widevine L3 allows extraction of decryption keys via TEE analysis. Bypass tools circulate publicly. The protection of premium content depends on the robustness of the DRM — and on how hard it is to analyze.
Sports streams: billions in rights exposed in real time
Illicit IPTV networks broadcast hijacked streams in real time to millions of subscribers. Sports broadcasting rights are worth billions of euros — their direct violation is hard to prosecute without identifying the technical interception vector.
Studios and platforms: protection algorithms exposed
Ransomware on a platform doesn't just expose data — it exposes the proprietary protection algorithms, the watermarking keys, the anti-piracy mechanisms. These assets are worth as much as the content itself.
Very large platforms: annual independent audit
The DSA mandates annual risk assessments and independent audits for very large platforms. NIS2 classifies certain streaming operators as OES.

OUR SERVICES

QREDTEAM

ADVERSARY SIMULATION

  • Streaming-platform Red Team — simulation of unauthorized access to premium content

QUARKSLAB DIFFERENTIATOR

DRM vendors test their own systems with an inherent bias. Generalist providers lack the depth on Widevine or PlayReady implementations. Quarkslab combines TEE reverse-engineering expertise (TrustZone, SGX) with DRM-protocol analysis and client-code protection via QShield — a chain no one else in Europe can offer in this segment.

WHAT WOULD WE SAY TO EACH OTHER, FACE TO FACE

Has your DRM been audited by someone genuinely trying to extract its keys — not to certify it compliant?

DRM certifications verify that the system meets technical specifications. They don’t verify how long it takes a motivated researcher to extract the keys. These two questions have very different answers — and only the second one actually protects your content.

Widevine, PlayReady, FairPlay at the TEE level
We audit DRM implementations where the keys actually live. Not a functional test — an analysis of physical and software resistance to extraction.
Apps, SmartTV, STB — like a pirate
We reverse-engineer your streaming clients to find the weaknesses pirates look for — and give them to you before they do.
Tamper-proof client code
QShield obfuscates the code of your streaming clients. Your DRM implementations remain your industrial secret.
Forensics preserved against sophisticated pirates
We test the robustness of your forensic watermarks against advanced bypass techniques.
