For example, one subject line is “You have a package coming from DHL.” The bodies of all of the emails we observed in this campaign are blank. Each email has a ZIP attachment containing a Visual Basic Script (VBS) file. Each file name for the ZIP files is a series of numbers separated by an underscore, such as 044450_64504154.zip. The VBS files have the same name as their ZIP file, except they have the VBS extension rather than the ZIP extension.
