Summary

  • Cisco Security has detected significant activity related to spam email messages that claim to contain a file for the recipient. The text in the email message attempts to convince the recipient to follow a link and view the details. However, the link directs the user to a malicious .rar file containing an .scr file that, when executed, attempts to infect the system with malicious code.

Email messages that are related to this threat (RuleID9532) may contain the following files:

> _MelillePony.rar
MelillePony.scr _

The MelillePony.scr file in the MelillePony.rar attachment has a file size of 134,144 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0x8E6295CE78D591EF2AB8632661ED1B36

Cisco Security analysts examine real-world email 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 email security threats and trends. Cisco will continue to monitor this threat and automatically adapt systems to protect customers. This report will be updated if there are significant changes or if the risk to end users increases.

Cisco security appliances protect customers during the critical period between the first exploit of a virus outbreak and the release of vendor antivirus signatures. Email that is managed by Cisco and end users who are protected by Cisco Web Security Appliances will not be impacted by these attacks. Cisco security appliances are automatically updated to prevent both spam email and hostile web URLs from being passed to the end user.
