HBO said it is continuing to investigate and is working with police and cybersecurity experts. The original version, as it was stolen from HBO's servers, was called "Vivianne Contact list", according to that source.
Game Of Thrones season 7 episode 5 summary leaked online. Hackers accessed 1.5 TB of data from HBO servers.
HBO spokesperson Jeff Cusson responded to WIRED's request for comment on the new leak in a statement, saying that the company had been expecting more data to emerge from its breach, but that the company's "forensic review is ongoing". Those documents include data like HBO CEO Richard Plepler's email contact list (with almost 40,000 entries) and a cast list for Game of Thrones that includes actor phone numbers, addresses, and email addresses.
A week after EW first reported that HBO was the victim of a major cyber attack, the hackers have upped the ante by releasing the emails of a network executive and demanding payment.
In its ransom letter, the group claimed that it took six months to breach HBO's security and demanded "our six-month salary in bitcoin", the AP reported, adding that the group claimed to have earned between $12 million and $15 million each year by stealing information and then blackmailing companies.
When hackers broke into HBO's systems last month, the cable network's executives told staffers that they didn't believe its email system had been compromised "as a whole". Another document appears to contain the confidential cast list for "Game of Thrones", listing personal cellphone numbers and email addresses for actors such as Peter Dinklage, Lena Headey and Emilia Clark.
Perhaps most troubling for HBO is the potential of having scripts and recordings from upcoming shows leaked.
"Our demand is clear and non-negotiable: we want XXXX dollars to stop leaking your data", the redacted note reads. They also claim that HBO marks their 17th target, and only three have failed to pay.
HBO has provided few details about the hack.
So far the HBO leaks, which have also included episodes of Larry David's "Curb Your Enthusiasm", have been limited, falling well short of the chaos inflicted on Sony in 2014.
