Fraud Alert: NACHA is being targeted by the Jabber/Zeus Trojan
Random individuals and/or companies may have received a falsified e-mail with the subject title "Rejected ACH Transaction." This e-mail appears to be from NACHA - The Electronic Payments Association telling them that there is a problem with an ACH transaction they have originated. The e-mail includes a link which redirects the individual to a fake web page which appears like the NACHA website and contains a link which almost certainly leads to a Jabber/Zeus malware download. Information about Jabber/Zeus Trojan can be found at ISAC Advisories 2009-10-009, 2009-06-036 and 2009-06-012.
