IRS: 330K Taxpayers Hit by ‘Get Transcript’ Scam

Summary: The IRS disclosed that identity thieves abused the "Get Transcript" feature on IRS.gov to pull sensitive tax data on more than 330,000 potential victims, up from the 110,000 it acknowledged in May 2015 after KrebsOnSecurity first raised alarms in March. The thieves used personal information from about 610,000 taxpayers to try to access old returns, succeeding on roughly 334,000, by answering four Equifax knowledge-based authentication questions that were navigated successfully more than half the times they were tried.

Bottom line: The same weak authentication still guards the IP PIN recovery feature, so the 330,000 people already notified may be exposed a second time through the IRS's own site. Static identifiers like a Social Security number and previous address are no longer secret, yet they remain the authenticator standing between a fraudster and a full tax transcript.
