FBI Formally Accuses North Korea In Sony Hacking
The FBI says it now has enough information to conclude that North Korea was behind the hacking of Sony Pictures.
The FBI said it tied the attack to North Korea because the malware used in the attack had the hallmarks of software written by the country in past.
"For example, there were similarities in specific lines of code, encryption algorithms, data deletion methods, and compromised networks," the FBI said in a statement.
The tools used, the FBI said, also have similarities to a cyber attack in March of last year against banks in South Korea.
The hack has caused serious repercussions for Sony. The stolen data has made public some embarrassing emails and has leaked unreleased movies and scripts.
The group that took responsibility for the attack, "Guardians of Peace," said it did so because Sony Pictures made a movie about the assassination plot of North Korean leader Kim Jong Un.
After the group issued further threats, movie theaters pulled The Interview and Sony decided against a Christmas Day release.
"We are deeply concerned about the destructive nature of this attack on a private sector entity and the ordinary citizens who worked there," the FBI said. "Further, North Korea's attack on [Sony] reaffirms that cyber threats pose one of the gravest national security dangers to the United States."
CNN reported earlier today that the hackers behind the attack issued another statement today, praising Sony for pulling the movie.
Removing it from screens, CNN reports the hackers said in email to Sony executives, was a "very wise" decision.
