Cyberwarfare Alert – White House computer network hit by sustained cyberattack

A sustained cyberattack that lasted almost two weeks was detected on the computer network used by officials of the Executive Office of the President, a White House official said.

The official said Tuesday that, while the cyber attack was detected, measures have been taken to address the activity on the Executive Office of the President’s (EOP) unclassified computer network. Officials have not disclosed who might be responsible for the attack, Reuters reported.

“In the course of assessing recent threats we identified activity of concern on the unclassified EOP network. Any such activity is something that we take very seriously. In this case we took immediate measures to evaluate and mitigate the activity,” the official told the agency.

So far, there’s no reason to believe classified networks were also hit, he said.

The White House – or the Executive Office of the President (EOP) – is routinely struck with cyber attacks, but the one revealed Tuesday had a more significant duration, affecting the system’s functionality for nearly two weeks. “Certainly a variety of actors find our networks attractive targets and seek to access to sensitive government information. We are still assessing the activity of concern, and we are not in a position to provide any additional details at this time,” the White House official said in a statement. The White House press pool reports sent by email Tuesday night were “significantly delayed,” pool reporter Steven T. Dennis of CQ Roll Call told Huffington Post. “Some people are getting pool reports significantly before other people.”
