One of the "what makes" mischief definitions could be any application that violates an institution's acceptable use policy (AUP).

Since many AUPs forbid the use of sniffers, any distribution with Ethereal/Wireshark could be considered in violation. I further suspect that many AUPs would also forbid pen testing tools such as Metasploit. And our
"no support" group is pretty down on password policy auditing/hacking tools such as John the Ripper, Cain and Abel, and similar tools... And I wouldn't even want to talk to them about ARP poisoning tools such as Ettercap.

Many security tools can be considered dual purpose tools. That is, in the hands of a skilled user, they can be used to minimize vulnerabilities. In the hands of an unethical/unsophisticated user they can be used to discover and exploit vulnerabilities. They could also produce an intended, or unintended, DoS attack.

So, another way to define "what makes" mischief could be the intention of the user.

Best of luck,
Uno
