Tax prep software company TurboTax has returned to normal operations after a 24-hour shutdown to battle an influx of fraudulent filings. The company temporarily halted its services on Feb. 5 after noticing a surge of filings using personal information that was flagged as stolen. Most victims of the identify theft found out about the criminal activity after their own attempts to file were rejected.
TurboTax's parent company, Intuit, says the problem was not due to an internal security breach. Spokesperson Julie Miller stated that the company thinks the stolen information was obtained by hackers who had breached another large company. Companies such as Blue Cross Blue Shield, JPMorgan Chase, Home Depot, and Target have all recently suffered security breaches, exposing over 80 million people to the threat of personal information theft.
Intuit has increased its anti-fraud systems and is working with security experts to investigate the attack.
