Case closed: AOL hacker sentenced By Margaret Kane March 28, 1997 7:12 PM EST PC Week Online A Yale University hacker who devised a program to let America Online customers avoid hourly charges was sentenced today to two years of probation and six months of home confinement. According to AOL, the sentencing closes the case with the first ever conviction of a crime that occurred on a private online service. Nicholas Ryan, a computer science student at Yale at the time of the 1995 incident, was also fined and ordered to pay AOL $62,000. Ryan, who went by the pseudonym Happy Hardcore, pled guilty to a felony offense under the Computer Fraud and Abuse Act in a federal district court in Alexandria, Va. Ryan's code, AOL4Free, allowed users to log-on to the service without paying hourly rates. In the installation instructions for an updated version of his software, Ryan wrote that AOL's software has a fundamental flaw in its design. "The simple fact is that a huge percentage of the actual work done in presenting the AOL experience is done not by the 'host' computer, the ones in Vienna, Virginia, but by the client AOL application you're running on your home Mac/PC," he wrote. "There's nothing you can do about the host, but you can, with enough skill, make the client do whatever you want." Reacting to the sentencing today, AOL's vice president of integrity assurance Tatiana Gau called the case a "legal milestone."
