NBC News is reporting that a Russian cyberattack has taken down the Pentagon’s Joint Staff unclassified email.

According to the officials, the “sophisticated cyber intrusion” occurred sometime around July 25 and affected some 4,000 military and civilian personnel work for the Joint Chiefs of Staff.

Sources are specifically pinning this on Russia.

After all, they’ve managed to hack the IRS, the White House, and the State Department. Why not go for the Pentagon now? It’s been proven, again and again, that our cyber security right now is an absolute joke.

Pro-tip to the GOP candidates tonight – make this an issue, FAST.
