Google Mending Another Crack in Widevine

Category: data securityDISC @ 12:05 pm

For the second time in as many years, Google is working to fix a weakness in its Widevine digital rights management (DRM) technology used by online streaming sites like Disney, Hulu and Netflix to prevent their content from being pirated.

The latest cracks in Widevine concern the encryption technology’s protection for L3 streams, which is used for low-quality video and audio streams only. Google says the weakness does not affect L1 and L2 streams, which encompass more high-definition video and audio content.

“As code protection is always evolving to address new threats, we are currently working to update our Widevine software DRM with the latest advancements in code protection to address this issue,” Google said in a written statement provided to KrebsOnSecurity.

In January 2019, researcher David Buchanan tweeted about the L3 weakness he found, but didn’t release any proof-of-concept code that others could use to exploit it before Google fixed the problem.
