The White House has ostensibly been compromised by Russian hackers and the U.S. believes it make know how this attack occured:

The White House in October said it noticed suspicious activity in the unclassified network that serves the executive office of the president. The system has been shut down periodically to allow for security upgrades.

The FBI, Secret Service and U.S. intelligence agencies are all involved in investigating the breach, which they consider among the most sophisticated attacks ever launched against U.S. government systems. ​The intrusion was routed through computers around the world, as hackers often do to hide their tracks, but investigators found tell-tale codes and other markers that they believe point to hackers working for the Russian government.

National Security Council spokesman Mark Stroh didn’t confirm the Russian hack, but he did say that “any such activity is something we take very seriously.”

“In this case, as we made clear at the time, we took immediate measures to evaluate and mitigate the activity,” he said. “As has been our position, we are not going to comment on [this] article’s attribution to specific actors.”

If true, this is a huge blunder and quite serious. It is about time for the White House to reconsider their current security architecture because it is obviously in need of an overhaul.
