Man cuts off internet connection in the whole country

Kaye compromised around one million individual devices while destroying company's service and reputation.

A self-taught British hacker has been jailed for a carrying out a massive cyberattack that knocked  an entire African nation offline two years ago.
Daniel Kaye, 30, admitted to hacking into phone company Lonestar in 2016, inadvertently crashing Liberia's internet in the process. He arrested when he arrived in the UK for a holiday in February 2017.
Kaye broke down on hearing his 32-month jail term at Blackfriars Crown Court in London. Judge Alexander Milne QC said Kaye had committed a "cynical" financial crime.
"Paradoxically, what is urged on your behalf is that you are an intelligent young man who knows what your powers can do. But that makes it all the more worrying that you used your abilities to carry out this attack," the judge said.
He was hired by an employee of rival firm Cellcom to carry out a series of Distributed Denial of Service (DDoS) attacks on Lonestar, flooding their bandwidth with multiple systems to make it impossible for their service to be delivered.
According to BBC report, Cellcom employee paid him around $10,000 (£7,800) a month however there is no suggestion the company knew what was happening.
Kaye compromised around one million individual devices while destroying Lonestar's service and reputation. He created his own botnet, a network of private computers infected with malicious software.
The weapon, called 'Mirai #14' hijacked a huge number of Chinese-made Dahua webcams which are used for security in homes and businesses around the world and exploited that to take over the devices without owners knowing in 2016.

He then ordered webcams to overwhelm Lonestar's systems by making them file date requests at Lonestar while working secretly out of Cyprus and controlling the botnet via his mobile phone.
This led hundreds of thousands of the webcams to fire data requests at Lonestar which in turn led the system to struggle to manage the demands and parts of the infrastructure crashed.
Kaye tried to pull in additional firepower by sending further attacks from Germany, where he had sought to hijack part of Deutsche Telekom's national infrastructure.
This led so much traffic at Lonestar, the entire national system jammed and the country's internet repeatedly failed between 3 November and 4 November 2016, investigators noted.
