WASHINGTON (7/23/10)--A phishing e-mail scam claiming to be from NACHA, the electronic payments association, has prompted an alert to key players, including financial institutions, in the electronic auto clearinghouse (ACH) payments system. NACHA received reports that individuals and/or companies received the e-mail. The subject line of the e-mail states, "Unauthorized ACH transaction," however, recipients should be alert for different variations of fraudulent e-mailes. The message contains a link that directs recipients to a fake Web page sporting a link with an executable virus with malware. NACHA warns recipients not to click on the link. "Both the e-mail and the related website are fraudulent," it said in the alert. "Do not follow Web links in unsolicited e-mails from unknown parties or from parties with whom you do not normally communicate, or that appear to be known but are suspicious or otherwise unusual," NACHA said. NACHA does not process or touch the ACH transactions that flow to and from organizations and financial institutions. It does not send out communications to individuals or organizations about individual ACH transactions that they originate or receive.
