[SingCERT] Enhancing the Security of Internet-Connected Devices
26 October 2016
Distributed Denial of Service (DDoS) attacks happen when vulnerable internet-connected devices are compromised by malware and used as bots in a DDoS attack. This advisory provides information on DDoS attacks, and how members of public can protect themselves from inadvertently aiding such an attack.
On October 21, 2016, there was a massive DDoS attack targeted at a Domain Name System (DNS) service provider, Dyn, bringing down major Internet platforms and services i.e. Twitter, Reddit, Github, etc. DNS are like telephone books or roadmaps of the Internet, maintaining a directory of domain names and their corresponding IP addresses.
