From PC World: Friday’s massive internet disruption came from hackers using an estimated 100,000 devices, many of which have been infected with a notorious malware that can take over cameras and DVRs, said DNS provider Dyn.
“We are able to confirm that a significant volume of attack traffic originated from Mirai-based botnets,” Dyn said in a Wednesday blog post.
The malware known as Mirai had already been blamed for causing at least part of Friday’s distributed denial-of-service attack, which targeted Dyn and slowed access to many popular sites in the U.S.
But on Wednesday, Dyn provided new findings, saying Mirai-infected devices were actually the primary source for Friday’s internet disruption.
The statement also suggests that the hackers behind the attack may have been holding back. Companies have observed variants of the Mirai malware spreading to more than 500,000 devices built with weak default passwords, making them easy to infect.
