"DDoS attacks are also becoming more common. Brian Krebs, an independent security researcher, observed earlier this month that the "source code" to the Mirai botnet had been released by a hacker group, "virtually guaranteeing that the internet will soon be flooded with attacks from many new botnets powered by insecure routers, IP cameras, digital video recorders and other easily hackable devices""
"The significance of the attack on Krebs is that it looks as though many of the attacks on him came from large numbers of enslaved devices - routers, cameras, networked TVs and the like. "Someone has a botnet with capabilities we haven't seen before," says Martin McKeay, Akamai's senior security expert. The DDoS arms race has just moved up a gear."
"This person or group, who go by the names BestBuy and Popopret, recently spammed an ad to folks on Jabber, an instant messaging service. They offered to perform a distributed denial of service (DDoS) attack on whomever their client(s) wanted, and they backed up their offer by claiming to wield the ability to perform some of the strongest DDoS attacks ever seen. Recent events in the history of the internet show us that these kind of attacks - if these hackers indeed have the power they claim - can wreak internet havoc by blocking user access to a range of some of the web's most popular destinations."
