Zombies can be used to conduct distributed denial-of-service (DDoS) attacks, a term which refers to the orchestrated flooding of target websites by large numbers of computers at once. The large number of Internet users making simultaneous requests of a website's server is intended to result in crashing and the prevention of legitimate users ...

The distributed denial-of-service (DDoS) attack was accomplished through numerous DNS lookup requests from tens of millions of IP addresses. [6] The activities are believed to have been executed through a botnet consisting of many Internet-connected devices —such as printers , IP cameras , residential gateways and baby monitors —that had ...

The trinoo or trin00 is a set of computer programs to conduct a DDoS attack. It is believed that trinoo networks have been set up on thousands of systems on the Internet that have been compromised by remote buffer overrun exploits. [1] The first suspected trinoo attacks are described in CERT Incident Note 99–04. [2]
