Every American's Social Security number, address may have been stolen in hack

After a group of hackers claimed to have stolen personal information several months ago from a data broker, a member of the group reportedly shared most of the sensitive data on an online forum for stolen data. 

The data includes 2.7 billion records of personal information from Americans including their Social Security numbers and physical addresses, Engadget reported, citing Bleeping Computer. 

A hacking group called USDoD claimed in April to have stolen personal records from National Public Data in a massive data breach.  The NPD is a platform that offers personal information to employers, private investigators, staffing agencies and others doing background checks, the Los Angeles Times reported, citing a class-action lawsuit filed in Fort Lauderdale, Florida.
