On the international scale, opportunities for computer espionage due to inadequate safeguards presents a major problem. Computer espionage by foreign governments may encompass military, industrial, economic and commercial objectives, with business firms being the most vulnerable. Inadequate safeguards are almost universally found against computer sabotage.
In November 1999 US citizen Eric Burns, age 19, who used the computer screen name "ZYKLON," was sentenced to 15 months imprisonment after pleading guilty to intentionally hacking a protected computer and causing damage. The defendant admitted that he had hacked and damaged computers in Virginia, Washington state, Washington, D.C., and London, England, including computers hosting the United States Information Agency and NATO pages on the World Wide Web, and the vice-president of the United States' Web page known as "21st Century.gov." Burns designed a program he called "Web Bandit" to identify computers on the Internet that were vulnerable to attack.
