As the Ransom ware is rapidly spreading all across the networks, we would like to bring to your awareness and alert you before you access any malawarenessgles or emails. Request you all to be extra careful before accessing any mails or documents.
How it works:
WannaCry is a form of ransomware that locks up files on your computer and encrypts them in a way that you cannot access them anymore. It targets Microsoft’s widely used Windows operating system.
What can you do to prevent infection:
According to Microsoft’s Malware Protection Center, here are the steps you should take to protect yourself against ransomware:
– Avoid clicking on links or opening attachments or emails from people you don’t know or companies you don’t do business with
– Ensure you have smart screen (in Internet Explorer) turned on, which helps identify reported phishing and malware websites and helps you make informed decisions about downloads
-Have a pop-up blocker running on your web browser
– Regularly backup your important files
How it spreads:
Ransomware is a programme that gets into your computer, either by clicking or downloading malicious files. It then holds your data as ransom. Some security researchers say the infections in the case of WannaCry seem to be deployed via a worm, spreading by itself within a network rather than relying on humans to spread it by clicking on an infected attachment.
The programme encrypts your files and demands payment in order to regain access. Security experts warn there is no guarantee that access will be granted after payment. Some forms of ransomware execute programmes that can lock your computer entirely, only showing a message to make payment in order to log in again. Others create pop-ups that are difficult or impossible to close, rendering the machine difficult or impossible to use.
