Germany has just tightened up its criminal code to make hacking into computer networks a more serious crime. It defines hacking as penetrating a computer security system and gaining access to secure data, without necessarily stealing data. Offenders are defined as any individual or group that intentionally creates, spreads or purchases hacker tools designed for illegal purposes. They could face up to 10 years in prison for major offenses. Other punishable cybercrimes include DOS (denial-of-service) attacks and computer sabotage attacks on individuals, which would extend the existing law that limited sabotage to businesses and public authorities. The new law, however, has drawn criticism by several groups, including the hacker club Chaos Computer Club e.V., which points to the work of "good" hackers, also known as "white hats," who work for security companies. These computer experts, the club argues, could be restricted in their ability to help software makers develop secure products and businesses to deploy them.
