Dyn, a company that supplies Internet services to numerous websites, including the likes of Twitter and Amazon, was targeted in a distributed denial of service (DDoS) cyberattack on October 21, 2016.
Experts have noted that this attack affected Dyn’s infrastructures located on the east coast. DDoS attacks are carried out using hacked systems to flood a specific site with “junk traffic” to shut down the site. As a result, error messages began to appear to legitimate users attempting to access their services on the affected sites.
According to security expert Brian Krebs, the attacks started around 7:10 a.m. EST and continued throughout the day. CSO reported that officials believe the Mirai botnet contributed to the attack. The Mirai bot searches the Web for Internet of Things (IoT) devices (i.e. home security cameras and DVRs) with factory-default usernames and passwords. Those devices are then used to attack specific sites.
After reviewing activity logs from the attack, experts speculate that the attack could have been orchestrated by amateurs.
