Aggressive scammers are impersonating the U.S. Internal Revenue Service (IRS) in e-mails designed to trick potential victims into paying fabricated outstanding amounts related to missed or late payments.
The phishing emails target users of Microsoft’s Office 365 platform and have so far reached an estimated number of up to 70,000 mail inboxes according to researchers at email security company Abnormal Security.
