The FBI warned U.S. businesses that hackers have used malicious software to launch destructive attacks in the United States, following a devastating cyberattack last week at Sony Pictures Entertainment.
The five-page, confidential “flash” warning issued to businesses late on Monday provided some technical details about the malicious software that was used in the attack, though it did not name the victim.
Officials are still analyzing the Sony attack, which caused serious damage to that company’s databases, according to NBC News.
The message threatened to release “secrets and top secrets” of the company. Currently being investigated is a connection between upcoming Sony movie “The Interview,” and North Korea.
The FBI occasionally issues “flash” warnings to provide businesses with details about emerging cyber threats to help them defend against new types of attacks. It does not name the victims of those attacks in those reports.
The report said that the malware overrides data on hard drives of computers which can make them inoperable and shut down networks.
