Botnets
Botnets have existed for at least a decade. As early as 2000, hackers were breaking into computers over the Internet and controlling them en masse from centralized systems. Among other things, the hackers used the combined computing power of these botnets to launch distributed denial-of-service attacks, which flood websites with traffic to take them down.

But now the problem is getting worse, thanks to a flood of cheap webcams, digital video recorders, and other gadgets in the "Internet of things." Because these devices typically have little or no security, hackers can take them over with little effort. And that makes it easier than ever to build huge botnets that take down much more than one site at a time.

Cybercriminals Abuse Mobile Applications to Launch DDOS Attacks

Cybercriminals Abuse Mobile Applications to Launch DDOS Attacks | 21st Century Learning and Teaching | Scoop.it
From news.softpedia.com - January 15, 2014 11:12 AM
Distributed denial-of-service (DDOS) attack protection solutions provider Prolexic has published its Global DDOS Attack Report for the fourth quarter ...

 

“The prevalence of mobile devices and the widespread availability of downloadable apps that can be used for DDoS is a game changer,” explained Stuart Scholly, president of Prolexic. 

 

Malicious actors now carry a powerful attack tool in the palm of their hands, which requires minimal skill to use. Because it is so easy for mobile device users to opt-in to DDoS attack campaigns, we expect to see a considerable increase in the use of these attack tools in 2014,” Scholly added.

What Is DNS and Why Does It Make the Internet Break? | #ICT #CyberSecurity #DDoS #CyberAttacks  | 21st Century Learning and Teaching | Scoop.it
From gizmodo.com - October 31, 2016 6:01 PM
Today, half of America’s internet shut down when hackers unleashed a large distributed denial of service (DDoS) attack on the servers of Dyn, a major DNS host. It’s still unclear exactly who carried out the attack and why, but regardless, the event served as a demonstration of how easily large swaths of the web can be wiped out if attacked by determined hackers.

What is a DoS attack really? | LEARNing basics of CyberSecurity | EDU | eSkills | 21st Century Learning and Teaching | Scoop.it

What if your computer is infected and participates in the attack? That would use your computer resources and slow down your Internet connection, not to speak about all the other dangers of having malware on your system. Keeping the device clean is a combination of common sense when surfing and opening attachments, and having a decent protection program installed. So you can participate in fighting DoS-attacks by caring for your own cyber security.

Hackers turn 162,000 WordPress sites into DDoS attack tools

Hackers turn 162,000 WordPress sites into DDoS attack tools | 21st Century Learning and Teaching | Scoop.it
From www.v3.co.uk - March 11, 2014 10:42 AM
Legitimate sites forced to aid criminals' illicit botnet operations


Hackers have hijacked more than 162,000 legitimate WordPress sites, connecting them to a criminal botnet and forcing them to mount distributed denial-of-service (DDoS) attacks, according to security firm Sucuri.


Sucuri CTO Daniel Cid said the company uncovered the botnet when analysing an attack targeting one of its customers. Cid said Sucuri managed to trace the source of the attack to legitimate WordPress sites.

"The most interesting part is that all the requests were coming from valid and legitimate WordPress sites. Yes, other WordPress sites were sending random requests at a very large scale and bringing the site down," read the blog.
