Wanna Cry Wreaks Havoc Worldwide
As you may have seen or read this weekend, a new variant of ransomware has been spreading like wildfire across more than 100 countries. This version arrives just like most other ransomware attacks, via attachments in email. What makes this one more dangerous is once a user clicks on the malware link, the application executes, encrypts files on the local device, and then attempts to replicate itself to any other windows devices that are on the network.
