Usually spam messages that have the malware in their attachments contain more files in the email that are legitimate to lure users into opening the infected one. The legitimate files may be of the following extensions:
docx, pdf, doc, jpeg, bmp, png

bat, exe, cmd
This is why expertes always advise to take caution in what mails you open online and to always use spam filters that block out mails of the same character sent from suspicious addresses.

  • Settings to conceal active processes from the Windows Task Manager.
  • Tools to monitor the infected PC’s screen and take screenshots.
