Just in time for tax season, hackers are escalating their efforts to impersonate the Internal Revenue Service in attempts to defraud taxpayers, the Research and Education Networking Information Sharing and Analysis Center, or REN-ISAC, warned on Monday. In an advisory, the organization warned I.T. executives and business officers to watch for suspicious e-mails and phone calls from people claiming to represent the I.R.S. and to protect personal information.

"Every tax season brings a host of fraudulent activities from scammers utilizing a variety of tactics," Kim Milford, executive director of REN-ISAC, said in an e-mail. "This year seems to be even worse than past years, with rampant reports of phishing, phone scams and fraudulent filings."
