Kenneth Schuchman, the alleged author of a supercharged variant of Mirai malware called Satori, has been rearrested for violating his bail conditions. In what may be a coincidence, security researchers say a Satori botnet went dormant following Schuchman's arrest, only to be reawakened later.
One of the co-authors of the devastating Mirai botnet malware has been sentenced to home incarceration and community service, and ordered to pay $8.6 million in restitution, for his role in a series of damaging distributed denial-of-service attacks that disrupted operations at Rutgers University.
Two years after Mirai botnets first appeared, security researchers say telnet-targeting botnets are attempting to compromise internet of things devices by pummeling them with 1,065 different username/password combinations. Some of these attacks are designed to install Linux DDoS malware.
Not only are we now seeing the most powerful DDoS attacks ever recorded, but they also are leveraging the ever-growing army of IoT devices. Gary Sockrider of NETSCOUT Arbor offers advice for detection and defense.
Spain's central bank says its website was intermittently offline as it struggled to repel a distributed denial-of-service attack. The temporary disruption is a reminder "stresser/booter" DDoS-on-demand services remain inexpensive, easy to procure and often effective.
Police recently arrested the suspected administrators and top users of the stresser/booter service Webstresser.org. Unfortunately, the plethora of such services means the world is unlikely to see a reduction in DDoS attack volumes, says Darren Anstee of Arbor Networks.
Old technology never dies, but rather fades "very slowly" away, as evidenced by there being 21 million FTP servers still in use, says Rapid7's Tod Beardsley.
