The FBI has concluded that one of the theories about the hacking attack against Sony — that a disgruntled Sony employee was the cause — doesn’t stand up, reports Politico.
FBI investigators met for three hours Tuesday with cyber intelligence firm Norse, concluding that the alternate theory doesn’t provide an accurate understanding of the evidence. An official told Politico that while investigators are open to new information, Norse’s evidence was “narrow” and didn’t provide an accurate analysis of the information.
“Norse had said it found evidence pointing to a disgruntled employee as the source of the Sony hack and offered the research to the FBI, which scheduled the meeting,” the story notes.
The report adds: “When asked about the briefing yesterday, the FBI released a short generic statement saying it was standing by its earlier assessment that the North Korean government was responsible for the crippling attack on Sony and there was ‘no credible information’ to suggest otherwise.”
