DDoS attack
According to admissions made in connection with his plea, from at least in or about July 2015 through in or about March 2017, Gammell engaged in a campaign of distributed denial of service (DDoS) attacks on websites throughout the United States. A DDoS attack is a malicious attempt to disable or interrupt service to a computer or website, usually by causing large amounts of Internet traffic to be directed to the computer or website. Gammell directed DDoS attacks at a number of victims’ websites, including websites operated by companies he used to work for, companies that declined to hire him, competitors of his business, and websites for law enforcement agencies and courts, among others.
