Science and Engineering Desk: Happened a few years ago. Hemanthakumar Goswami, an employee of a private technology firm, received a call. First, he was given a message by an automated voice—that the Wi-Fi router he was using at home had been hacked. As a result, fraudsters can hack all the laptops, computers, smartphones that are connected to the Internet through that router at any time. Malware can enter through it and take over all the gadgets. Therefore, Hemant is asked to press 1 button on the mobile to update the security features of the router immediately. When he pressed that number again, he introduced himself as a customer care executive and started talking to him. Trying to find out the password of his router. Being an employee of a technology company, Hemant did not fall into the trap easily. But cyber experts say it's also a big trap for fraud. It can happen to anyone.

How exactly does the cheating cycle work?
According to cyber experts, the phone that came to Hemant is a trick to hack the password of the WiFi router. Here, if a scared broadband customer gives his WiFi router ID or password, it can be easily hacked by fraudsters. In addition to this, they can change the password of the router by taking advantage of various mistakes of the customer. But Hemant did not fall into this trap, as it is true, it is also true that in most cases routers can be hacked by my-yours, i.e. ordinary broadband customers.

So that cybercriminals can take control of many gadgets at once by directly hacking the broadband router. Experts explain that a router usually falls victim to fraudsters when its software is not regularly updated or passwords are not changed regularly. In that case, fraudsters can easily get hold of the broadband router used for internet connection in an individual or an organization. According to a survey by a company called 'CyberScoop', at least 83 percent of broadband router users do not update their routers regularly.

What could be the result?
First of all, fraudsters can take over your smartphone, laptop or computer. Then the damage is severe. According to police and cyber experts, many people use this internet connection to do important work like daily office work, children's education, shopping, banking transactions. As a result, if a router is hacked, fraudsters can steal account passwords and even banking information in all cases.

They can then use that information to hack into customers' accounts. Again, they can also find opportunities to blackmail you in various ways by stealing the passwords of social media accounts. It may also happen that a ransomware attack is launched with the capture of all important data related to your office or business.

What is the way to escape from this? Cyber ​​experts say, first of all, you need to update your router's software regularly, because security features are also updated with it. Password should also be changed regularly. As for passwords, make it a habit to give passwords that are a bit complex (eg mix of capital and small letters, symbols, numbers). Enable firewall protection and WiFi encryption to protect the WiFi router.
