An unofficial guide to Ransomware
What is Ransomware ?
Ransomware is a kind of computer program which is designed to prevent user access to the computer till a certain amount of money is paid. This amount of money is paid to creators of the Ransomware program. However, paying that amount of money still does not ensure your data to be safe or protected. Many times, even after paying for the access, it has been found that user data has been lost or stolen. Paying even doesn’t ensure that you can ever gain your computer access or stored data back.
What is the Payment Method ?
Once your Computer has been attacked by a Ransomware, you are forced to pay a sufficiently large amount to programmers. This amount is collected in Bitcoin because of the anonymity it offers. Therefore, it is never advisable to pay to Ransomware for access to your system. Instead, get help of cyber security experts which will help you in recovering access and data.

Similarly, Financial data can also be compromised at large scale using ransomwares. About 54% companies in United States faced Ransomware attacks. About 70% of organizations paid for Ransom.
