Friends, Due to the evolving technology, new technologies are constantly being explored. New technological tools are evolving. Which is why today anyone has access to some technology devices like Smartphone, Tablet, Television, Laptop or Computer etc. So today everyone is becoming smarter and smarter due to the use of technology. There are also advantages and disadvantages to overuse of technology. Some people use technology illegally. An excellent example of this is when transferring money online or giving a Ford person a four-digit OTP number on our mobile number, as well as our secure password if a stranger finds out they can use it illegally. So in the digital age now digital theft and ransom is starting to happen. For that we need to go one step further than hackers and stay safe. With the advent of Corona, the use of computers or laptops for work or online classes has increased. With that in mind, some hackers have also become active. We call the illegal work done by such hackers as digital theft or digital ransom. It is also important to take precautions against hackers. November 30 is celebrated every year as 'National Computer Securities Day' to keep abreast of technology. Its purpose is to make people aware of computer securities.
