Russian Hackers Have Been in White House System for Months, Officials Say

Russian hackers penetrated the White House non-public, non-classified computer system for several months last year, forcing the White House to shut down the system for several days, U.S. officials said.

The hacked system is not used for classified information, but is used by the White House advance and press office, the general counsel’s office, and officials in the budget and legislative liaison offices.
