Both the Tories and Lib Dems have backed government measures to increase penalties for UK computer hackers which could lead to 10 years' imprisonment under new legislation.
The move follows campaigning from Labour MP Tom Harris, whose ideas are now being adopted in the Police and Justice Bill.
There will be a clearer outlawing of offences like denial-of-service attacks which are showing steady growth.
The bill - which was being debated for the first time in the House of Commons earliert this week, also raises the penalty for using hacking tools.
Home Secretary Charles Clarke commented: "We need to recognise that in our increasingly interdependent world, work with international partners to tackle terrorism and serious organised crime will be increasingly important.
"One of the growing new threats that can only be tackled through extensive international cooperation is the continued threat posed by computing hacking and denial-of-service attacks."
The bill passed on to its second reading without a vote
