Answer 1

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

It's been touted as a technological revolution that will make things easier by connecting everything from your fridge to your toaster online.

But there's a darker side to the so-called Internet of Things: A massive army of infected IoT devices is one of the most effective ways to launch massive cyberattacks.

"There's so much enthusiasm for connected devices, But unfortunately, "bad security practices are still the norm in IoT." Such practices vary, from coding passwords directly into device software or using no encryption, but the result is often the same: A device that can be hacked much easier.

That fundamental lack of basic security was on full display in 2016 when a "record" distributed denial-of-service attack was carried out against the website of journalist Brian Krebs, which took his site offline for days. While the massive influx of traffic resulted in Krebs' host kicking him off its servers, it seemed to be just the beginning of a new wave of IoT-led attacks.

"This is not isolated to a specific type of manufacturer or specific type of product but rather, all these connected devices are showing issues, who helps run a security research village for IoT devices at the Def Con hacking conference, said.

The attack on Krebs was carried out by a botnet of infected IoT devices. Put simply, this network of infected devices is made a slave to an attacker, who uses software to find connected devices with weak security.

And it's not a closely-guarded secret as to how the botnet is assembled: Just a week after Krebs' site was taken offline, the source code for the software that did it, Mirai, was released online - which means we can expect many others to use and improve upon the malicious code

A large portion of the devices that were used in recent cyber attacks were cameras and digital video recorders made by a Chinese manufacturer, The Wall Street Journal reported. Others included routers and satellite antennas.

Kindly revert for any queries
