Reflection amplification is a technique that allows cyber attackers to both magnify the amount of malicious traffic they can generate, and obfuscate the sources of that attack traffic. For the past five years, this combination has been irresistible to attackers, and for good reason. This simple capability, of turning small requests into larger, 'amplified' responses, changed the Distributed Denial of Service (DDoS) attack landscape dramatically. more
Possibly the first documented native IPv6 DDoS attack reported today suggests a DNS dictionary attack which originated from around 1,900 different native IPv6 hosts, on more than 650 different networks. more
According to Akamai, the incident was the largest attack seen to date, "more than twice the size of the September 2016 attacks that announced the Mirai botnet and possibly the largest DDoS attack publicly disclosed." more
In mid-March, the group dubbed by Wired Magazine 20 years ago as Crypto-Rebels and Anarchists - the IETF - is meeting in London. With what is likely some loud humming, the activists will likely seek to rain mayhem upon the world of network and societal security using extreme end-to-end encryption, and collaterally diminish some remaining vestiges of an "open internet." Ironically, the IETF uses what has become known as the "NRA defence": extreme encryption doesn't cause harm, criminals and terrorists do. more
The story about securing the DNS has a rich and, in Internet terms, protracted history. The original problem statement was simple: how can you tell if the answer you get from your query to the DNS system is 'genuine' or not? The DNS alone can't help here. You ask a question and get an answer. You are trusting that the DNS has not lied to you, but that trust is not always justified. more
In 2018, Internet Governance will be one of the top priorities in the geo-strategic battles among big powers. In today's world, every global conflict has an Internet-related component. There is no international security without cybersecurity. The world economy is a digital economy. And human rights are relevant offline as well as online. It is impossible to decouple cyberspace from the conflicts of the real world. more
It is one of those surreal, ironic moments in time. This coming week, an event called the Internet Governance Forum (IGF) 2017 will be held at Geneva in the old League of Nations headquarters now known as the Palais des Nations. On its agenda is a workshop to discuss "A Digital Geneva Convention to protect cyberspace." If the IGF participants, as they enter the Palais grounds, simply look in the opposite direction south across the Place des Nations, they would see 100 meters away, a glass cube building provided by the Republic and Canton of Geneva. more
A colleague was recently commenting on an article by Michele Neylon "European Data Protection Authorities Send Clear Message to ICANN" citing the EU Data Commissioners of the Article 29 Working Party, the grouping a determinate factor In the impending death of WHOIS. He is on point when he said: What the European Data Protection authorities have not yet put together is that the protection of people's mental integrity on the Internet is not solely due to the action of law enforcement... more
One of the problems with trying to secure systems is the lack of knowledge in the community about what has or hasn't worked. I'm on record as calling for an analog to the National Transportation Safety Board: a government agency that investigates major outages and publishes the results. In the current, deregulatory political climate, though, that isn't going to happen. But how about a voluntary system? more
Rep's Graves and Sinema recently introduced H.R. 4036, the catchily named Active Cyber Defense Certainty Act or ACDC act which creates some exceptions to criminal parts of computer crime laws. Lots of reports have decried "hack back" but if you read the bill, it's surprisingly well targeted. The first change is to what they call Attributional Technology, and says it's OK to put bait on your computer for an intruder intended to identify the intruder. more
Former Yahoo CEO Marissa Mayer apologized today at the Senate Commerce, Science and Transportation hearing regarding massive data breaches at the internet company, blaming Russian agents. more
The argument for end-to-end encryption is apparently heating up with the work moving forward on TLSv1.3 currently in progress in the IETF. The naysayers, however, are also out in force, arguing that end-to-end encryption is a net negative... The idea of end-to-end encryption is recast as a form of extremism, a radical idea that should not be supported by the network engineering community. Is end-to-end encryption really extremist? Is it really a threat to the social order? more
One of the most profoundly disruptive developments occurring in the cyber security arena today is the headlong rush by a set of parties to ubiquitously implement extreme End-to-End (e2e) encryption for communication networks using essentially unbreakable encryption technology. A notable example is a new version of Transport Layer Security (TLS) known as version 1.3. The activity ensues largely in a single venue... more
The website designated by Dell Inc. to help customers recover from malicious software and other computer maladies may have been hijacked for a few weeks this summer by people who specialize in deploying said malware, reports Brian Krebs in KrebsOnSecurity. more
In his book "The Darkening Web: The War for Cyberspace" (Penguin Books, New York 2017), Alexander Klimburg, an Austrian-American academic, gives "Internet Dreamers" a "Wake Up Call". He tells us the background-story why people start to be "anxious about the future of the Internet", as the recent ISOC Global Internet Report "Paths to Our Digital Future" has recognized. Klimburg refers to Alphabets CEO Erich Schmidt, who once said that "the Internet is the first thing that humanity has built that humanity does not understand". more
