Dutch police have arrested a teenager suspected of involvement in the Operation Payback distributed denial-of-service (DDoS) attacks following the latest WikiLeaks revelations.
The Dutch High Tech Crime Unit said that a 16 year-old boy was arrested last night "presumably involved in the digital attacks by sympathisers of WikiLeaks to include the web sites of MasterCard and PayPal".
An investigation was launched as soon as Dutch police realised that the attacks originated in The Netherlands.
The teenager has confessed to attacking MasterCard and Visa but, given the distributed nature of the attacks, it is unlikely that he had much more than a minor role.
"The boy is probably part of a larger group of hackers, to which the investigation continues," said the Dutch High Tech Crime Unit.
Research from security firm Imperva has revealed that the tool used to create the voluntary botnet which has been launching the denial of service attacks on the aforementioned sites has been downloaded over 40,000 times, most often in the US.
"The tool was originally developed as an open-source network stress-testing tool. It was recently tweaked to include a central command-and-control module," explained chief technology officer Amichai Schulman.
"Operation Payback's ability to challenge serious sites and do that simultaneously is very much coupled to the introduction of the new version with its [command-and-control] capabilities."
It has not all been one way traffic though. The Anonymous online collective responsible for the Operation Payback attacks has had its own back-end infrastructure hit by DDoS, according to Panda Security.
