The text in the email message attempts to convince the recipient to open the attachment to view a copy of the document. 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 (RuleID8479) may contain the following files:

The oyto.exe file size in the swift tt copy (2).rar attachment is unavailable. The MD5 checksum is also unavailable.
