Adrian Lamo attended high schools in Bogotá and San Francisco, from which he did not graduate, but received a GED and was court-ordered to take courses at American River College, a community college in Sacramento County, California. Lamo began his hacking efforts by hacking games on the Commodore 64 and through phone phreaking. Activities and legal issues Lamo first became known for operating AOL watchdog site Inside-AOL.com. Security compromise Lamo was a grey hat hacker who viewed the rise of the World Wide Web with a mixture of excitement and alarm. He felt that others failed to see the importance of internet security in the early days of the World Wide Web. Lamo would break into corporate computer systems, but he never caused damage to the systems involved. Instead, he would offer to fix the security flaws free of charge, and if the flaw wasn't fixed, he would alert the media. Lamo hoped to be hired by a corporation to attempt to break into systems and test their security, a practice that came to be known as red teaming. However, by the time this practice was common, his felony conviction prevented him from being hired. In December 2001, Lamo was praised by Worldcom for helping to fortify their corporate security. In February 2002, he broke into the internal computer network of The New York Times, added his name to the internal database of expert sources, and used the paper's LexisNexis account to conduct research on high-profile subjects. The New York Times filed a complaint, and a warrant for Lamo's arrest was issued in August 2003 following a 15-month investigation by federal prosecutors in New York. At 10:15 a.m. on September 9, after spending a few days in hiding, he surrendered to the US Marshals in Sacramento, California. He
