Increasing numbers of teenagers are starting to dabble in hi-tech crime, say experts.
Computer security professionals say many net forums are populated by teenagers swapping credit card numbers, phishing kits and hacking tips.
The poor technical skills of many young hackers means they are very likely to get caught and arrested, they say.
Youth workers added that any teenager getting a criminal record would be putting their future at risk.
"I see kids of 11 and 12 sharing credit card details and asking for hacks," said Chris Boyd, director of malware research at FaceTime Security.
Many teenagers got into low level crime by looking for exploits and cracks for their favourite computer games.
Communities and forums spring up where people start to swap malicious programs, knowledge and sometimes stolen data. Some also look for exploits and virus code that can be run against the social networking sites popular with many young people. Some then try to peddle or use the details or accounts they net in this way."
