Summary

  • Cisco Security has detected significant activity related to Portuguese-language spam e-mail messages that claim to contain a payment receipt for the recipient. The text in the e-mail message attempts to convince the recipient to follow a link and view the payment details. However, the link directs the user to a malicious .zip file containing a .cpl file that, when executed, attempts to infect the system with malicious code.

E-mail messages that are related to this threat (RuleID4226) may contain the following files:

> Comprovante_436_PDF.zip
Comprovante_436_PDF.cpl

The Comprovante_436_PDF.cpl file in the Comprovante_436_PDF.zip attachment has a file size of 211,968 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0xDEC75B9D243B0E874F15D9E9FCCB6CB4

The following text is a sample of the e-mail message that is associated with this threat outbreak:

Cisco Security analysts examine real-world e-mail traffic data that is collected from over 100,000 contributing organizations worldwide. This data helps provide a range of information about and analysis of global e-mail security threats and trends. Cisco will continue to monitor this threat and automatically adapt IronPort systems to protect customers. This report will be updated if there are significant changes or if the risk to end users increases.

Cisco IronPort Virus Outbreak Filters protect customers during the critical period between the first exploit of a virus outbreak and the release of vendor antivirus signatures. E-mail that is managed by Cisco and end users who are protected by Cisco IronPort web security appliances will not be impacted by these attacks. Cisco IronPort appliances are automatically updated to prevent both spam e-mail and hostile web URLs from being passed to the end user.
