Washington Post: Federal agents notified more than 3,000 U.S. companies last year that their computer systems had been hacked, White House officials have told industry executives, marking the first time the government has revealed how often it tipped off the private sector to cyberintrusions.
The alerts went to firms large and small, from local banks to major defense contractors to national retailers such as Target, which suffered a breach last fall that led to the theft of tens of millions of Americans’ credit card and personal data, according to government and industry officials.
