Taxpayer Data Breach Worse Than Previously Thought

PHILADELPHIA (CBS) – The breach of taxpayers' data is much worse than the IRS previously thought.

A Treasury Department investigation reveals the number of people caught up in last year's cybertheft is roughly 720,000.

The IRS will warn affected taxpayers about potential identity theft and offer them free credit protection.

They will also get an additional personal identification number to protect future tax filings.

The IRS has disabled the online tool used to steal personal information.
