COMPUTER TAMPERING

Computer tampering statutes tend to be broad in nature and most seek to proscribe unauthorized modifications of computer programs or the way in which a computer or computer network operates. Because of their broad scope, computer tampering statutes can be used as a catchall when a state lacks other statutes expressly punishing particular computer-related criminal activities. Computer tampering charges can often be brought together with other charges, and because of their often lenient penalties should only brought without other offenses where a state lacks alternative substantial means to prosecute an offender.

In some situations, such as with California, if a state has dealt directly with a particular category of computer crime within the context of a larger encompassing computer crime statute, we have included in our statutory analysis a cross reference to the relevant subsection of that state’s statute. We have denoted states that are also listed in our general computer crime statute section with a ‘*’.
