U.S. Internal Revenue Service Commissioner (IRS) testified before the Senate Finance Committee stating the agency has discovered fraudsters could use someone's personal data to fill out a financial aid application, and the "Data Retrieval Tool" would populate the application with tax information. Selena Larson reporting in CNN: "That information could be used to file false tax returns. The commissioner said fewer than 8,000 of these returns were processed, and refunds were issued totaling $30 million. ... IRS flagged 100,000 accounts of people who started the application, used the Data Retrieval Tool, but then didn't finish it. The IRS is alerting those people, as they may have had their information compromised ... 2016 tax season saw a 400% increase in phishing and malware."
