The U.S. Internal Revenue Service (IRS) has reported that the hack into its computer databases, was much more extensive than first thought. The IRS said tax return information of about 114,000 U.S. taxpayers had been illegally accessed by cyber criminals over the preceding four months, with another 111,000 unsuccessful attempts made.
A new review has identified 220,000 additional incidents where data was breached, the tax collection agency said. It identified another 170,000 suspected failed attempts by third parties to gain access to taxpayer data. Former FBI cyber agent and security experts from tripwire and lancope commented on IRS breach.
