Conclusion Introduction There are no precise, reliable statistics on the amount of computer crime and the economic loss to victims, partly because many of these crimes are apparently not detected by victims, many of these crimes are never reported to authorities, and partly because the losses are often difficult to calculate.

Nevertheless, there is a consensus among both law enforcement personnel and computer scientists who specialize in security that both the number of computer crime incidents and the sophistication of computer criminals is increasing rapidly.

Experts in computer security, who are not attorneys, speak of "information warfare". While such "information warfare" is just another name for computer crime, the word "warfare" does fairly denote the amount of damage inflicted on society. Two comments on word usage in this essay: I normally write in a gender neutral way, but here I use the masculine pronoun for computer criminals, because 1 female computer criminals are rare and 2 I can't imagine a feminist attacking me because I deny equal recognition to women criminals.

E-mails with bogus From: Posting messages in an Internet newsgroup or online bulletin board with a false author's name that is intended to harm the reputation of the real person of that name.

These acts might be punishable by existing criminal statutes that prohibit impersonation, forgery, deceit, or fraud.

However, a judge might decide that the specific language in old statutes about writing or signature does not apply to e-mail.

Rather than write new statutes for forged e-mail addresses or unauthorized sending of e-mail in someone else's name, I would prefer that legislatures broaden the existing criminal statutes for analogous crimes with paper and ink.

Similar issues arise in both: Unauthorized Use Unauthorized use of computers tends generally takes the following forms: The criminal reads or copies confidential or proprietary information, but data is neither deleted nor changed.

Inthe Melissa virus infected a [possibly confidential] document on a victim's computer, then automatically sent that document and copy of the virus via e-mail to other people. Subsequently, the SirCam and Klez malicious programs made a similar release of [possibly confidential] documents from a victim's computer.

These malicious programs are a new way to release confidential information from a victim's computer, with the confidential information going not to the author of the malicious program, but to some person unknown to the author of the malicious program. For example, change a grade on a school transcript, add "money" to a checking account, etc.
