Welcome to the video tutorial of mech tech. Here I will show you What is Wanna cry Ransomware? How to Protect Yourself from Wanna Cry Ransomware? How do I Prevent WannaCry Ransomware: 1. Backup your computer immediately 2. Update your operating system 3. Inatall Microsoft Security Bulletin MS17–010 WannaCry ransomware MS17 010 patch download and install: http://ift.tt/2n7sKua The WannaCry ransomware is made up of two main parts: the ransomware itself — which encrypts users’ files — and the SMB worm — the component that spreads the ransomware to random computers that have an exposed SMB port (port 445). Port 445 in Windows is by default used by “Server” service (real name is “lanmanserver”) to provide file sharing via SMB protocol. To prevent Windows from listening on this port you need to stop and disable this service. The ransomware’s SMB worm takes advantage of a vulnerability that Microsoft patched via security bulletin MS17–010 way back in March. Because WannaCry attacks were so bad, on Saturday, Microsoft also released extra patches for the SMB exploit for old operating systems it stopped supporting years before, such as Windows XP, Windows 8, and Windows Server 2003.
