The upcoming fifth season of Netflix’s ‘Orange is the New Black’may turn out to be Hollywood’s biggest breach since the Sony hack in 2014. But security experts aren’t surprised by the incident, even as details about it still emerge. That’s because many have been warning of weak security at third-party vendors for years.

“Third-party vendors have been a problem for a long time and will continue to be in the future,“ said PwC principal Mark Lobel during an interview with Variety. Lobel declined to specifically comment on this weekend’s Netflix leak, which appears to be based on a security breach at Larson Studios, an audio postproduction company that has also been working on shows like “Fargo,“ “Designated Survivor“ and “NCIS Los Angeles.“ But he argued that security for third-party vendors continues to be a weak link for Hollywood.
