Fraudlent E-mails Appearing to Come from NACHANACHA, the system which processes ACH transactions between banks, has been the victim of sustained and evolving phishing attacks in which consumers and businesses are receiving emails that appear to come from NACHA. The attacks are occurring with greater frequency and increased sophistication. Perpetrators may also be exploiting email addresses recently stolen from Epsilon.These fraudulent emails typically make reference to an ACH transfer, payment, or transaction and contain a link or attachment that infects the computer with malicious code when clicked on by the email recipient. The contents of these fraudulent emails vary, with more recent examples including a counterfeit NACHA logo and the citation of NACHA’s physical mailing address and telephone number.NACHA itself does not process nor touch the ACH transactions that flow to and from organizations and financial institutions. NACHA does not send communications to persons or organizations about individual ACH transactions that they originate or receive.If malicious code is detected or suspected on a computer, consult with a computer security or anti-virus specialist to remove malicious code or re-install a clean image of the computer system. Always use anti-virus software and ensure that the virus signatures are automatically updated. Ensure that the computer operating systems and common software application security patches are installed and current.Additional information and guidance on phishing is available from the Federal Deposit Insurance Corporation (FDIC).
