The distributed denial of service attacks against dynamic domain name service provider Dyn this morning have now resurged. The attacks have caused outages at services across the Internet.
But this second wave of attacks appears to be affecting even more providers. According to Dan Drew, the chief security officer at Level 3 Communications, the attack is at least in part being mounted from a "botnet" of Internet-of-Things (IoT) devices.
Drew explained the attack in a Periscope briefing this afternoon. "We're seeing attacks coming from a number of different locations," Drew said. "AnĀ Internet of Things botnet called Mirai that we identified is also involved in the attack."
