If you are thinking you are safe from Ransomware...You are not...you have to be vigilant..
In a very simple term, Ransomware is a malicious software that blocks access to data and encrypts the files.A message is displayed asking for the payment to get the files back.
Anybody using a system can be hit by it starting from home computers to servers at government sectors or at private sectors. The payment is asked in Bitcoin, a type of digital currency used for online transactions between individuals. There is no guarantee that paying the ransom will give you access to your files or PC.
While initially it was popular in Russia, the scam has grown internationally and now 74 countries have been affected by Ransomware.
How it spreads-
According to the USComputer Emergency Readiness Team (USCRT), outdated or unpatched softwares are attacked easily by Ransomware. Experts say that Wannacry is a software that spreads copies of itself by hacking into other computers on network rather than prompting users to open unsuspected attachments.
