The Recent and Rapid Evolution of DDoS Attacks

In October of 2016 the Mirai botnet came thundering onto the internet landscape. A digital Godzilla, a DDoS King Kong, this Internet of Things-powered behemoth began smashing DDoS attack records, online powerhouses like Reddit, Etsy, Spotify, CNN and the New York Times crumbling under its fists. When the dust had settled, and services had been restored, one thing seemed certain: a new era of DDoS attacks was upon us. Mirai was terrifying as a botnet but even worse as a harbinger. more

1 Terabit DDoS Attacks Become a Reality; Reflecting on Five Years of Reflections

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

DDOS and the DNS

The Mirai DDOS attack happened just over a year ago, on the 21st October 2016. The attack was certainly a major landmark regarding the sorry history of "landmark" DDOS attacks on the Internet. It's up there with the Morris Worm of 1988, Slammer of 2002, Sapphine/Slammer of 2009 and of course Conficker in 2008. What made the Mirai attack so special? more

The IoT Needs a Paradigm Shift from Security to Safety of Connected Devices

Building IoT ventures from scratch by prototyping hardware devices and their backend systems as well as working for a large company that tries to sell IoT devices itself, we learned a lot about the pitfalls and problems concerning security in the IoT. Nearly every connected device out there proved to be vulnerable to attacks. Researchers showed that it's possible to remotely take control over autonomous vehicles, implanted medical devices were manipulated, voting machines compromised and of course all sorts of other "smart" devices... more

The Internet is Dead - Long Live the Internet

Back in the early 2000s, several notable Internet researchers were predicting the death of the Internet. Based on the narrative, the Internet infrastructure had not been designed for the scale that was being projected at the time, supposedly leading to fatal security and scalability issues. Yet somehow the Internet industry has always found a way to dodge the bullet at the very last minute. more

No One is Immune: Qatar Crisis Started by a Targeted Poli-Cyber Attack

The Qatar Crisis started with a targeted Poli-Cyber hack of an unprecedented nature. Its shockwaves and repercussions continue to alter political and business fortunes, directions and paradigms not only in the Gulf region but globally. Almost everyone around the world is now aware of the this crisis that started early June. By mid July a Washington Post report cited US intelligence officials that the UAE orchestrated hacking of Qatari government sites, sparking regional upheaval that started it all. 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

Sorry, Not Sorry: WHOIS Data Must Remain Public

In March, I posted a call to action to those of us in the community who have the inclination to fight against a movement to redact information critical to anti-abuse research. Today, I felt compelled to react to some of the discussions on the ICANN discussion list dedicated to the issue of WHOIS reform: Sorry, not sorry: I work every working hour of the day to protect literally hundreds of millions of users from privacy violating spam, phish, malware, and support scams. 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
