White House dismisses cyberattack as culprit in Dow Jones plunge

White House Counterterrorism Adviser John Brennan said he has no indication that a cyberattack was behind the Dow's 1,000-point plunge last week.

There’s no indication that a cyberattack was behind the Dow Jones industrial average’s nearly 1,000-point plummet and the partial rebound on May 6, according to White House Counterterrorism and Homeland Security Adviser John Brennan.

“To my knowledge there’s no indication that it was” the result of a cyberattack, Brennan said during a May 9 Fox News Sunday interview. 

Some people have speculated that the plunge could have been caused by some sort of electronic attack on computer systems integral to trading. Officials continue to investigate what caused the incident.
