This morning a co-worker received an email from DHL with an attachment. The attachment was titled "UPS_Print_Label_912.zip" and inside was an executable with an icon of a MS Word document. At the time neither Prevx 3.0, MBAM, or Panda Cloud was detecting anything malicious. I uploaded to Virus Total and someone else had already uploaded it a few hours ago. At the time only 15/40 were able to detect it. I decided to submit the sample to several companies, one of them being McAfee, as a password protected zip renamed to .zi_p in order to pass thru Gmail. I even tested the file before submitting to make sure you would be prompted for a password upon opening the file. McAfee Labs - Beaverton replied: I can only assume the "bot" was unable to process the file since the extension was renamed. Even then it should be passed on to a real analyst for further inspection. Has anyone else had issues submitting samples to McAfee?
