Many cyber attacks against companies today go unreported, and more still are undetected... Timing and context are everything. The faster a company identifies a problem, and the faster and deeper it is understood and its relevance to the business, the more effectively the company can respond. We call this squeezing the cyber response curve. This two-part post will discuss the current state of cyber threats, what the cyber response curve is and its impact your organization and how you can effectively squeeze this curve to improve attack response. more
In an after-action analysis of the Mirai botnet attacks on Dyn, business intelligence firm, Flashpoint has assessed with "a moderate degree of confidence" that the perpetrators behind the attack were most likely not politically motivated, and most likely not nation-state actors. more
South Korea's ruling party chairman has offered to resign over a cyberattack reported to have been orchestrated by an aide to one of the conservative party's lawmakers. The move comes after police concluded the distributed denial-of-service (DDoS) attacks on the election watchdog's website on the day of by-elections in October was masterminded solely by a 27-year-old aide to the ruling Grand National Party. The aide has also admitted to orchestrating a similar cyberattack on the website of Park Won-soon, who was elected Seoul mayor in the Oct. 26 elections. more
A number of websites owned and operated by the United States Congress are recovering from a three-day DNS attack. more
We recently received an email from a customer asking about hybrid DDoS mitigation and its ability to stop large application layer attacks. Here's the truth: Hybrid DDoS mitigation works and can stop large application layer attacks. Hybrid DDoS mitigation typically involves a purpose-built DDoS mitigation appliance or software on dedicated hardware that sits immediately in front of or behind an enterprise's edge router. more
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
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
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
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
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
"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
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 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
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
