Summary

  • Cisco Security has detected significant activity related to spam email messages that claim to contain an invoice statement for the recipient. The text in the email message attempts to convince the recipient to open the attachment to view the invoice. However, the .rar 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 (RuleID9878) may contain the following files:

> profoma invoice_1.rar
profoma invoice.exe

The profoma invoice.exe file in the profoma invoice_1.rar attachment has a file size of 372,736 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0xFD703BE8670ADE259CE60D9FD42E2650

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