According to Forbes, the IRS has filed an amended statement on the ‘Get Transcript’ hack — which reports that 700,000 U.S. taxpayer accounts were accessed or targeted, and 47 million transcripts have been ordered to date.
Now, the Internal Revenue Service says Social Security numbers for more than 700,000 people were compromised.
The breach was discovered last May. Hackers potentially stole Social Security numbers, birth dates and other information that could be used for identity theft.
The IRS said the hackers used taxpayer information acquired from outside the IRS to answer personal identity questions to access tax return information.
The breach was first revealed in May and it was reported that more than 114,000 accounts had been accessed. Then it was disclosed that another 220,000 accounts had been compromised in August. It added another 390,000 to that total this week bringing it close to 724,000.
The IRS is notifying anyone whose personal information was stolen through the mail, as well as offering free identity protection for a year.
