A Hacker Tool is any software application that performs a wide range of hacking related tasks without user's permission. Activities include: disabling a user's anti-virus software or personal firewalls, gaining access to sensitive data, removing copy protection and modifying system settings.
A tool that explores another system, looking for vulnerabilities. While these can be used by security managers, wishing to shore up their security, the tools are as likely used by attackers to evaluate where to start an attack.
