German Chaos Computer Club CCC has uncovered two recent instances of police using "trojan" spying programs on the computers of suspects they later arrested.
The programs allowed remote users to take over webcams, eavesdrop on internet phone calls and take screenshots of the user's activity every 30 seconds.
Some of those activities, if they took place, would have brake the law in Germany, which only allow authorities to monitor computers for phone calls.
That trojan software has been sold to other countries in Europe, not just Germany.
