Russian hackers crack Pentagon email system

WASHINGTON: A group of Russian hackers breached a security protocol of US military’s Joint Chief of Staff’s classified email system, says Martin Dempsey the then Joint Chief of Staff Chairman, CBS News reported on Thursday.

Dempsey did not appear on camera, he said, the director of the National Security Agency, Admiral Mike Rogers, informed him about the attack in an early morning by a phone call in 2015.

The system which was attacked is used in Pentagon by 3,500 military officers and civilians who work for the chairman.

The hackers got the password and the signature of Martin Dumpsey who retired in September 2015, and the hundreds of passwords of other users who works through the  email system. The hackers were good at their job and the only way to stop the hack was to take the network down.

Now, US official blames Russia that the attack was intended not to spy but a full-on assault, the only purpose was to cause damage and force Pentagon to replace the hardware and software and It took two weeks to recover from the damage, reported CBS.

The Pentagon declined to comment.

US officials have accused Putin of supervising his intelligence agencies’ hacking of the US presidential election in an effort to help Republican Donald Trump. Russian officials have denied accusations of interference in the Nov. 8 election won by Trump.
