Three men have pleaded guilty to federal cyber-crime charges which includes creating a botnet know as Mirai which was used to take down a huge part of the internet in 2016.
According to documents revealed on Wednesday, Paras Jha,21, Josiah White,20, and Dalton Norman,21, admitted to one count of conspiracy in a plea agreement filed this month.
Federal prosecutors in Alaska and New Jersey have accused the three hackers of creating and using the Mirai botnet to hijack vulnerable internet-connected devices which they used in launching several distributed denial-of-service (DDoS) attacks.

A distributed denial-of service (DDoS) attack is used to disrupt online services by sending spam traffics in their thousands, millions, billions and even terabytes so as to knock that particular service offline. This is usually conducted via a botnets of ensnared vulnerable devices such as routers, webcams and other IoTs.
According to Jha plea agreement. The filling says the 21-year who is a former Rutgers University computer science student "conspired to conduct DDoS attacks against websites and web hosting companies located in the United States and abroad," and then demanded payment to put a stop to the attack.
Jha admitted to have release the Mirai source code to the public which was then used by cyber-criminals to conduct several DDoS attacks in 2016 on top internet services such as Netflix,Twitter, Reddit, Spotify, Theverge, BBC, Dyn, Pinterest, xbox.com and others
However, prosecutors on the case have said that they do not believe that three men were responsible for the attacks in 2016 as Jha had already posted the code to online forums which was then used by cybercriminals to cause havoc worldwide.

Jha and Norman also pleaded guilty to a separate conspiracy charge for using another powerful botnet for a clickfraud scheme, to generate fake clicks which they used in defrauding advertisers.
White has pleaded guilty to creating the Mirai scanner which scans vulnerable devices which are then enslaved in the botnet. Norman too has admitted to developing exploits which they built into the botnet.
The three hackers were all a fan of Japenese anime called 'Mirai Nikki' and so named the botnet Mirai. The name Mirai Nikki means 'future diary' diary in English.
