Social engineering+trojan horse=LexisNexis

An article from Wired details the exploits of the three young hackers (16,19 and 20) who broke in to the LexisNexis databases and had access to the personal data of over 300,000 people. Of particular interest is the account of how they got access to the law enforcement database by posing as a 14-year old girl in a chat room, locating somebody they believed to be a police officer monitoring the channel and subsequently sent them a set of pictures laced with a trojan horse which then provided them with information from the officer's computer.
