The Director of the FBI James Comey offered his most direct retort to date to those who doubt the Bureau’s case against the Democratic Peoples Republic of Korea (DPRK), saying that the hackers who pillaged Sony Pictures Entertainment were “sloppy” and revealed the source of the attack – IP addresses linked to the reclusive government, Ars Technica reports.
Comey was speaking at ICCS, the International Conference on Cyber Security in New York City on Wednesday. He said that, while the Sony attackers largely concealed their identity by using proxy servers, on several occasions they “got sloppy” and connected directly to Sony’s network, revealing their own IP address in the process.
Those slip-ups provided evidence linking North Korea to the attack on Sony’s network, he claimed.
The IP address isn’t the only evidence, however. (Thankfully.) Comey also said that “analysts at the FBI found the patterns of writing and other identifying data from the attack matched previous attacks attributed to North Korea.” It’s not clear if those patterns of writing are different from the patterns of writing that have already been analyzed – and found wanting.
Even then, Comey assured the audience that “there was other evidence…that he could not share publicly.”
