Diddling is intentionally changing information stored on a computer or network. For example, a hacker could change school grades, erase telephone bills, or embezzle funds. Superzapping involves illegally bypassing passwords and other security measures that limit access to computer files and then stealing the information. Furthermore, some people destroy data on the host systems. They infect the data with infectious programs called viruses and trojans.
Viruses can replicate, infect and destroy data at preset times.
For example, the Michaelangelo virus is set to go off on March 6th, which would then destroy the data on the computer. Trojans are like a disguise for a destructive program which is sometimes inserted onto the host system and upon executing it, the trojan will destroy or disrupt the system and its data. All these crimes are dealt with in the Criminal Code of Canada. Furthermore, in Section 342.1, under the heading Unauthorized Use of Computer, the hacker can be charged for accessing and using the host system without authorization. This crime can be punishable on an indicted or summary conviction.
