A piracy group known as "iON" has reportedly released the first episode of Netflix's Ultra HD version of Breaking Bad on a private BitTorrent website. This would mark the first time that Netflix's Ultra HD content, which is protected by a previously unbroken form of digital rights management (DRM), has appeared online in a pirated format.At 17.73 GB, the file is roughly 50 times the size of an equivalent standard definition video.While Ultra HD content is still somewhat rare—Netflix and Amazon only stream select programming in Ultra HD, which is also known as 4K—the release of Breaking Bad could represent a dramatic escalation in the battle between Hollywood and tech-savvy pirates. Before now, pirated Ultra HD content was primarily limited to niche content like pornography.It remains unclear how iON was able to circumvent the DRM protecting the Ultra HD file. The licensing agreement between Sony (which produces Breaking Bad) and Netflix notes that the Ultra HD file is digitally watermarked to identify the account that leaked the file.In response to the incident, Netflix noted that piracy is a "global problem," and that it is "actively working" on ways to protect its content.
