Security researchers have unearthed a booming botnet-for-hire business operating out of China.
According to security firm Damballa, the IM Distributed Denial of Service (DDoS) service allows any one interested in bringing down a website to hire a botnet and operate it using a simple web interface.
Damballa (opens in new tab) explained that the hackers had registered a number of compromised web domains in March.
The service works like any other business model, in which potential customers are required to visit the website and open an account to highlight the domains they want to attack.
The company explained: “The infected hosts are rallied and then instructed to launch a coordinated DDoS attack against the victim of choice.”
The botnet, which began testing in April 2010, was running 25,000 DNS lookups every hour by August 2010.
Damballa estimates that as many as 10,000 PCs were being compromised by the botnet every day, making it one of the largest botnets still active on the internet.
