Amid a rash of cyber attacks, Federal officials told more than 3,000 companies last year that their systems had been compromised, The Washington Post reported.
In a report late Monday, The Post said the government sent notices to a host of small and large corporate entities, including local banks, defense contractors and major retailers like Target. Last November, the retail giant disclosed a massive breach of customers' personal data.
The newspaper said the notifications were part of an effort by the Federal Bureau of Investigation, Department of Homeland Security and other agencies to share information with U.S. companies. It was the first time the government put a number on how often it tipped off the private sector to data breaches, The Post added.
