IRS Says ID Thieves Stole Info on 100K Taxpayers

Identity thieves used the IRS’ own systems to steal personal information from about 100,000 taxpayers, the agency said on Tuesday, according to the Associated Press.

Criminals already armed with some data on the taxpayers used the IRS “Get Transcript” website to obtain even more data on their victims, the IRS said.

Get Transcript gives taxpayers the ability to obtain tax returns from previous years. Visitors to the Get Transcript page at the IRS on Tuesday afternoon were greeted by the message: “Alert: The online Get Transcript service is currently unavailable. Transcripts may still be ordered using the Get Transcript by Mail service. We apologize for any inconvenience.”

The IRS said criminals had accessed the site from February through mid-May, and that it was shut down in reaction to the attack. Criminals armed with taxpayers’ Social Security numbers and other information were able to pass security tests and access the system.

“The IRS notes this issue does not involve its main computer system that handles tax filing submission; that system remains secure,” the agency said in a statement, according to AP. “In all, about 200,000 attempts were made from questionable email domains, with more than 100,000 of those attempts successfully clearing authentication hurdles.”

Reuters reported that IRS Commissioner John Koskinen said the criminals were part of an organized, professional gang.

“We’re confident these are not amateurs, these are actually organized crime syndicates that not only we but everyone in the financial industry are dealing with,” he said at a news conference.

The IRS is notifying taxpayers impacted by the attack.
