Thieves stole data on 100,000 taxpayers through IRS app

Criminals stole sensitive information about roughly 100,000 taxpayers through the Internal Revenue Service’s “Get Transcript” application, a major data breach at the U.S.’s national tax agency.

The thieves first stole information including Social Security details, dates of birth and street addresses from an outside, non-IRS source, the government agency said Tuesday.
