DDoS Attack

Nitol and 3322.org Takedown by Microsoft

Reading this morning's blog from Microsoft about "Operation b70" left me wondering a lot of things. Most analysts within the botnet field are more than familiar with 3322.org - a free dynamic DNS provider based in China known to be unresponsive to abuse notifications and a popular home to domain names used extensively for malicious purposes - and its links to several botnets around the world. more

Maintaining Security and Stability in the Internet Ecosystem

DDoS attacks, phishing scams and malware. We battle these dark forces every day - and every day they get more sophisticated. But what worries me isn't just keeping up with them, it is keeping up with the sheer volume of devices and data that these forces can enlist in an attack. That's why we as an industry need to come together and share best practices - at the ICANN community, at the IETF and elsewhere - so collectively we are ready for the future. more

Blocking a DDoS Upstream

In the first post on DDoS, I considered some mechanisms to disperse an attack across multiple edges (I actually plan to return to this topic with further thoughts in a future post). The second post considered some of the ways you can scrub DDoS traffic. This post is going to complete the basic lineup of reacting to DDoS attacks by considering how to block an attack before it hits your network -- upstream. more

Black Frog: Next Generation Botnet, No Generation Spam Fighting

Black Frog -- a new effort to continue the SO-CALLED Blue Security fight against spammers. A botnet, a crime, a stupid idea that I wish would have worked -- News items on Black Frog. Blue Frog by Blue Security was a good effort. Why? Because they wanted to "get spammers back". They withstood tremendous DDoS attacks and abuse reports, getting kicked from ISP after ISP. ...The road to hell is filled with good intentions. Theirs was golden, but they got to hell, quite literally, non-the-less. ...When Blue Security went down, some of us made a bet as to when two bored guys sitting and planning their millions in some café would show up, with Blue Security's business plan minus the DDoS factor. Well -- they just did. more

A Noteworthy Report on Fast Flux Hosting

This very interesting document was released by ICANN's Generic Names Supporting Organization (GNSO) for public comment yesterday. And it asks some fundamental questions while at the same time pointing to sources such as the Honeynet Alliance's reports on fast flux. more

Oracle Launches Internet Intelligence Map Providing Insight Into the Impact of Internet Disruptions

Oracle today announced the launch of the Internet Intelligence Map website; a source available for free that provides country-level connectivity statistics based on traceroutes, BGP, and DNS query volumes on a single dashboard. more

Cyber-Terrorism Rising, Existing Cyber-Security Strategies Failing, What Are Decision Makers to Do?

While conventional cyber attacks are evolving at breakneck speed, the world is witnessing the rise of a new generation of political, ideological, religious, terror and destruction motivated "Poli-Cyber™" threats. These are attacks perpetrated or inspired by extremists' groups such as ISIS/Daesh, rogue states, national intelligence services and their proxies. They are breaching organizations and governments daily, and no one is immune. more

Canadian Internet Registration Authority Launches Cloud-Based DNS Firewall Service

The Canadian Internet Registration Authority (CIRA) has announced the launch of a security service called D-Zone DNS Firewall -- a cloud-based cybersecurity solution -- to protect Canadian organizations from rasomware and malware. more

So Long, Farewell: The Worst DDoS Attacks of 2016

The year 2016 will go down in infamy for a number of reasons. It was the year an armed militia occupied an Oregon wildlife refuge, Britain voted to Brexit, an overarching event that will simply be referred to as The Election occurred, and Justin Bieber made reluctant beliebers out of all of us. 2016 was also the worst year on record for distributed denial of service (DDoS) attacks by a margin that can only be considered massive. more

Frequency of DDoS Attacks Risen by 40% While Duration of Attacks Decrease

The frequency of DDoS attacks has risen by 40% year on year while the duration of attacks decreased with 77% lasting ten minutes or less, according to a new report released by Corero Network Security. more

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more

Anti-Spoofing, BCP 38, and the Tragedy of the Commons

In the seminal 1968 paper "The Tragedy of the Commons" , Garrett Hardin introduced the world to an idea which eventually grew into a household phrase. In this blog article I will explore whether Hardin's tragedy applies to anti-spoofing and Distributed Denial of Service (DDoS) attacks in the Internet, or not... Hardin was a biologist and ecologist by trade, so he explains "The Tragedy of the Commons" using a field, cattle and herdsmen. more

FBI, DHS Release Technical Details on North Korea’s DDoS Botnet Infrastructure

U.S. Department of Homeland Security (DHS) and the FBI today released a technical alert based joint-effort analysis of methods behind North Korea’s cyberattacks. more

‘First True’ Native IPv6 DDoS Attack Reported

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

Conventional Thinking Won’t Work in New Era of ISIS & ‘Unprecedented’ Cyber & Non-Cyber Attacks

Conventional thinking or solutions will no longer work in the new era of ISIS and the 'Unprecedented' cyber and non-cyber attacks we live in today. Like it or not, everyone is impacted, and no one is immune. Whether you are an average citizen, a chairman or CEO of a multinational, or a government or academic institution leader, the questions to ponder are: Do you know what to do next? Do you know what the solution is? more
