Hackers are selling their services to take down websites on the internet for significantly less than the minimum wage they would get if they were in officially registered employment.
The attacks carried out by the hackers are known as a distributed denial of service (DDoS) and occur when a website is overloaded with traffic, causing it to crash. DDoS attacks are not particularly sophisticated.
The idea of selling such a service online is not new, but cybersecurity company Arbor Networks, managed to track a hacker known as "Forceful" down and get an insight into how it works, and more importantly how much the person is earning from their services.
In the case of Forceful, the hacker posted an advert on a Russian-language forum online, listing their prices and contact information. People can then use secure messaging apps to get in touch and negotiate the logistics.
