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

An Overview of the 27th DNS Operations, Analysis, and Research Center Meetings

The DNS Operations, Analysis, and Research Center (DNS-OARC) meetings are an instance of a meeting that concentrates on the single topic of the DNS, and in this case, it delves as deep as anyone is prepared to go!

The hot topic of the meeting was the news that the proposed roll of the Key-Signing-Key of the root zone of the DNS, originally scheduled for October 11, was to be postponed. more

On Sept. 27, Internet Corporation for Assigned Names and Numbers (ICANN) announced that the first root zone Key Signing Key (KSK) rollover - originally scheduled to take place on Oct. 11 - will be postponed. Although this was certainly a difficult decision, we fully agree that erring on the side of caution is the best approach to take. In this blog post, I want to explain some of the involvement Verisign has had in KSK rollover preparations, as well as some of the recently available research opportunities which generated data that we shared with ICANN related to this decision. more

ICANN's last new gTLD application closed in 2012 with more than 600 brands applying for their dot brand. Dot brand domains associate a keyword or keyphrase and a brand name in a complete domain name... To understand better how the evolution of the dotBrand has been throughout these years, number of websites launched, redirects, registries etc, Dot Brand Observatory prepared a few visual graphics. more

Probability of ROI and Tighter Network Security by Blocking Malicious Subdomains

Failing to block a stealthy malicious host from making connections to your network could cost your company millions of dollars, a damaged reputation, and severe losses in sensitive private data. Threat intel teams have faced on-going problems: Expensive feeds that are slow to catch new threats; Chasing false positives in alerts wastes time and money; and Vendors selling a new appliance for every ill. Would 100% of your users Spot the Bot? more

ICANN Complaint System Easily Gamed

ICANN's WDPRS system has been defeated. The system is intended to remove or correct fraudulently registered domains, but it does not work anymore. Yesterday I submitted a memo to the leadership of the ICANN At-Large Advisory Committee (ALAC) and the greater At-Large community. The memo concerns the details of a 214-day saga of complaints about a single domain used for trafficking opioids. more
