BOSTON:- The U.S. Federal Bureau of Investigation warned U.S. businesses that hackers have used malicious software to launch destructive attacks in the United States, following a devastating cyber attack 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.
Two cybersecurity experts who reviewed the document and were familiar with the Sony attack said that they were sure the agency was referring to the breach at the California-based unit of Sony Corp
“This correlates with information about that many of us in the security industry have been tracking,” said one of the people who reviewed the document. “It looks exactly like information from the Sony attack.”
FBI spokesman Joshua Campbell declined comment when asked if the software had been used against the California-based unit of Sony Corp, though he confirmed that the agency had issued the confidential “flash” warning, which Reuters independently obtained.
“The FBI routinely advises private industry of various cyber threat indicators observed during the course of our investigations,” he said.”This data is provided in order to help systems administrators guard against the actions of persistent cyber criminals.”
It does not name victims of attacks in those reports.
