In March 2014, Quantum Booter, which is a service provided to paying customers that will issues a denial of service (DDoS) on websites, was breached and approximately 48,600 member accounts were disclosed online including those members’ email addresses, IP addresses, passwords, private messages and usernames.
A distributed denial of service, or DDos, is an attack on another person’s website that will often result is the site being taken down and possibly also infected with a virus. Quantum Booter’s website markets themselves as a service to see if your own website can handle a DDoS attack and does not specifically state that it’s a service that will issue the DDoS on a third-party’s website.
