Summary

• Cisco Security has detected significant activity related to spam email messages that contain a payment notification for the recipient. The text in the email message attempts to convince the recipient to open the attachment and view the payment details. However, the .zip attachment contains a malicious .exe file that, when executed, attempts to infect the system with malicious code.

Email messages that are related to this threat (RuleID7281) may contain the following files:

> Service_Message_011013.zip
Service_Message_011013.exe

The Service_Message_011013.exe file in the Service_Message_011013.zip attachment has a file size of 26,112 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0x0D9AA2BCED9A0B53A5B970C58D7B09CB
