A new variant of ransomware known as Petwrap (or Petya) is being spread through phishing emails that contain a Dropbox link to a fake resume. If you click on the link, it executes a file that crashes and reboots your computer. Your computer will display an image with a skull and crossbones and a message that the hard drive has been encrypted and the only way to retrieve your data is to pay a ransom.
HOW TO AVOID BEING HACKED:
1). Do not click on any links embedded in emails.
2). Do not open unexpected email attachments.
