San Bruno, CA (PRWEB) August 30, 2006
Following a recent increase in scam emails, the Internal Revenue Service reminded taxpayers to be on the lookout for bogus emails claiming to be from the tax agency. The IRS saw an increase in complaints about these emails, which are designed to trick the recipients into disclosing personal and financial information that could be used to steal the recipients’ identity and financial assets. This practice is known as phishing.
IronPort Systems, the leader in gateway security, has confirmed an increase in these scams. IronPort’s Threat Operations Center identified the bogus email starting on July 28 and has since seen several variants of the email/phishing scam. In the last 12 months 110 different scams have been identified, with 23 of those coming in July and August.
The IRS scam/phishing attack is evidence that phishers are casting a wider net in hopes of luring victims with compelling content. Financial Services continue to be the most targeted industry sector, averaging 90% of all attacks.
IronPort reports phishing scams make up nearly 2% of all email. Total worldwide spam volume equals over 40 billion per day, up 40% year over year.
The bogus emails vary in form but typically claim to come from “taxrefunds @ irs.gov.” The email tells the recipient that he or she is eligible to receive a tax refund for a given amount. It then says that to access a form for the tax refund, the recipient must use a link contained in the email. The link then asks for the personal and financial information.
Identity theft is among the fastest and most devastating crimes in the United States. In 2006, more than nine million Americans were the victims of ID fraud. Individuals lose an average of $6,000 -- amounting to over $50 billion each year.
The IRS does not ask for personal identifying or financial information via unsolicited e-mail. Additionally, taxpayers do not have to complete a special form to obtain a refund. To check the status of this year’s refund, taxpayers can to the genuine IRS Web site at http://www.irs.gov and click on the interactive “Where’s My Refund” feature. Or they may contact the IRS toll-free at 1-800-829-1040 to determine whether the IRS is trying to contact them about a tax refund.
The IRS also has established an electronic mailbox for taxpayers to send information about suspicious e-mails they receive which claim to come from the IRS. Taxpayers should send the information to: phishing @ irs.gov.
