In Part One of this series, we examined internal server, network and infrastructure monitoring applications. Now let's take a look at another way to capture DDoS information: external performance monitoring... Unlike network/infrastructure tools - which are usually installed inside a customer's network - external performance monitoring solutions are typically provided by a third party and leverage monitoring locations from around the world. more
As DDoS attacks become larger, more frequent and complex, being able to stop them is a must. While doing this is part science, a matter of deploying technology, there is also an art to repelling sophisticated attacks. Arbor Networks, Citrix and others make great gear, but there's no magic box that will solve all your problems for you. Human expertise will always be a crucial ingredient. more
We've received enough interest about our previous notes on Iranian Internet connectivity that I wanted to give a brief update, and some reflections. In short: Iran is still on the Internet. As the crisis deepens, people are literally risking their lives by continuing to use the Internet for coordination and communication. more
The website of Swimming Australia has come under DDoS attack just hours after the Australian Bureau of Statistics went back online following a similar attack bringing the online census initiative to a halt. more
"We often refer to the Cuyahoga River in Cleveland that caught on fire over 20 times before we actually did something to introduce the Clean Water Act," says Allan Friedman, the director of cybersecurity initiatives for the Department of Commerce's National Telecommunications and Information Administration (NTIA), in conference call on Monday. more
As anyone who's been in the DDoS attack trenches knows, large multi-gigabit attacks have become more prevalent over the last few years. For many organizations, it's become economically unfeasible to provision enough bandwidth to combat this threat. How are attackers themselves sourcing so much bandwidth? more
Since the end of last year, amplification attacks have been increasingly used by attackers and received heavy media coverage. Everyday protocols not given much thought before, like Network Time Protocol (NTP), can be asked in a very short remote command to send a very large response (list of 600 clients last connected to the NTP server) to a spoofed IP address (the target) by the requestor/attacker. more
The entire internet infrastructure of the African nation of Liberia is distributed by the same weapon used to cause the historic cyberattack just two weeks ago. more
The Australian Bureau of Statistics reports deliberate and "malicious" attacks from offshore, designed to sabotage nation's first online 2016 Census. more
The 24th DNS-OARC meeting was held last week in Buenos Aires -- a two-day DNS workshop with amazingly good, consistent content. The programme committee are to be congratulated on maintaining a high quality of presentations. Here are my picks of the workshop. They fall into three groups, covering themes I found interesting... These presentations related to the ongoing problem of DNS as a source of reflection attacks, or a victim of attempted DDoS... more
Arbor Networks today released its Global DDoS Attack Data for the first half of 2016 affirming continued escalation in both the size and frequency of denial-of-service (DDoS) attacks. more
The Ministry for Information Society and Telecommunications of Montenegro has confirmed several key websites were targeted by cyberattacks on Sunday (16 October), the day of the country's parliamentary elections. more
OurMine claims credit for DDoS attack on Pokemon Go servers: Several news outlets have reported the hacking group OurMine - also notorious for compromising social media accounts of various celebrities - on Monday took responsibility of hacking the game servers. more
Whatever your personal perspective of the rights and wrongs of the current Arab-Israeli war in Gaza, there is a second front being fought on the Internet, says Jart Armin of HostExploit.com in a blog post today. "This form of warfare is a battle of words and often vivid imagery engaged by hackers from either side of the divide." more
During the last Computer Law Conference organized by ADIAR (Argentina Computer Law Association) and the Universidad Nacional de Sur, I gave a conference on the Internet of Things, cybercrime and dangerous situation presented by the lack of proper regulation -- a topic in which I have one of my research projects. At the moment some people argued that I was talking about something that might happen in a relatively distant future, dissenting with my view that the possibility was imminent.. more
