During last year’s tax season, the IRS warned of a 400% increase in phishing and malware attacks, which contributed to an estimated $21 billion of taxpayer money lost to fraudulent tax returns.

Here, Miriam Wugmeister and Robert Baehr outline the most common types of phishing attacks during tax season, offering practical guidelines for preventing your company from becoming the victim of an attack.
