The data is part a trove of information, including emails, passwords and credit card details hacked by the Anonymous collective over the past few weeks, including data taken from the US-based Stratfor security analyst company over the Christmas period.
The hacking collective says the aim of the campaign is to give "neo-nazis a good spanking".
Around 450 names and details of Polish citizens are included in the data haul in the protest action codenamed Operation Blitzkrieg.
Anonymous have also released details of far-right activists in Finland and Germany.
