something about the WannaCry ransomware, and are wondering what's going on, who
is doing this, and whether your computer is secure from this insanely
fast-spreading threat that has already hacked nearly 200,000 Windows PCs over
the weekend. Compared to other countries, India is still in its early stages of
adopting digital services. Which is why there has been a huge outcry about Aadhaar
and the data that it holds.
Wanna Cry Hits the computer which is running on Microsoft Windows Operating System. In Case of India , we are having more windows user and is still running in various government departments , offices and in Banks too .
The Reserve Bank of India has asked all the banks to put in place a software update at ATM to protect their systems from a malware that has attacked payment systems across the world.But after reading this awareness article, you
would be so cautious that you can save yourself from WannaCry, as well as other
similar cyber-attacks in the future.For those unaware, Ransomware is a computer
virus that usually spreads via spam emails and malicious download links;
specially designed to lock up the files on a computer, until the victim pays
the ransom demand, usually $300-$500 in Bit coins.
Now
bitcoin is a form of digital currency, the one who create this ransomware
demands the money in form of Bitcoins because owners of bitcoin addresses are
not explicitly identified. To heighten financial privacy, a new bitcoin
address can be generated for each transaction which means you can create a new
payment address for every sender. So No one can trace who is receiving the
money.
In today 1 bitcoin
costs = Rs.109821.76 Indian Rupee
