Cisco Security Intelligence Operations has detected significant activity related to spam e-mail messages that claim to contain a Citibank account validation request for the recipient. The text in the e-mail message attempts to convince the recipient to open the attachment that has a filename similar to a valid Citibank domain but is actually a malicious form. Instructions within the e-mail direct the user to input their banking information into the malicious form. If the user enters the information, the form may submit the information to that attacker, who could use that information as part of other fraudulent activity.
E-mail messages that are related to this threat (RuleID4105) may contain any of the following file:
