ISC Changes Name to Internet Systems Consortium

Internet Systems Consortium (ISC), formerly Internet Software Consortium, has changed its name to better reflect the new direction of the organization. The renamed company has expanded the mission of the original ISC to include more focus on Global DNS operations. In addition to developing and maintaining production quality Open Source software, such as BIND and DHCP, ISC will now enhance the stability of the global DNS through reliable F-root nameserver operations and ongoing operation of a DNS crisis coordination center, ISC's OARC for DNS; and further protocol development efforts, particularly in the areas of DNS evolution and facilitating the transition to IPv6. more

1.3 Tbps DDoS Attack Against GitHub is Largest Attack Seen to Date, Says Akamai

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

More on Broadband Router Insecurity and Being Proactive

Fergie replied on NANOG to my recent post on the subject of broadband routers insecurity: "I'll even go a step further, and say that if ISPs keep punting on the whole botnet issue, and continue to think of themselves as 'common carriers' in some sense -- and continue to disengage on the issue -- then you may eventually forced to address those issues at some point in the not-so-distant future..." He is right, but I have a comment I felt it was important - to me - to make. Not just on this particular vulnerability, but on the "war"... more

Diving Into the DNS

If you are at all interested in how the Internet's Domain Name System (DNS) works, then one of the most rewarding meetings that is dedicated to this topic is the DNS OARC workshops. I attended the spring workshop in Amsterdam in early May, and the following are my impressions from the presentations and discussion. What makes these meetings unique in the context of DNS is the way it combines operations and research, bringing together researchers, builders and maintainers of DNS software systems, and operators of DNS infrastructure services into a single room and a broad and insightful conversation. more

Are Botnets Run by Spy Agencies?

A recent story today about discussions for an official defense Botnet in the USA prompted me to post a question I've been asking for the last year. Are some of the world's botnets secretly run by intelligence agencies, and if not, why not? Some estimates suggest that up to 1/3 of PCs are secretly part of a botnet. The main use of botnets is sending spam, but they are also used for DDOS extortion attacks and presumably other nasty things like identity theft. But consider this... more

Three Reasons Why It Makes Sense to Deploy DNSSEC Now

As many of you may know, today .ORG announced that all of its 8.5 million domains are now able to be fully DNSSEC signed - the largest set of domain names in the world so far that has access to this key security upgrade. .. The widespread publicity that the Kaminsky bug got around the world vindicated a decision made in several companies to invest time, effort and money into deploying DNSSEC. The community was split on the value of the DNSSEC effort -- many thought the deployment was quixotic, while a few others thought it was appropriate. more

South Korean Banks Receive DDoS Threat from Hacker Group, Record Ransomware Payment Demanded

Various sources including South Korea's news agency Yonhap are reporting that a hacker group has threatened to launch a DDoS attack against seven South Korean banks unless they pay about 360 million won (US$315,000) in bitcoin. more

The Internet’s Weakest Link

This week two major transoceanic cables experienced outages that may last several days. The outages provide a reminder that several Internet bottlenecks exist where these cables make landfall. When one thinks of bottlenecks in telecommunications the first and last mile come to mind. Yet equally vulnerable are the last few 1000 feet of submarine cable links. more

NASA Teething Troubles Teach a DNSSEC Lesson

On January 18, 2012, Comcast customers found they could not access the NASA.gov website. Some users assumed that Comcast was deliberately blocking the website or that NASA, like Wikipedia and Reddit, was participating in the "blackout" protests against the Stop Online Piracy Act (SOPA) going on that day. As it turned out, the truth was much less exciting, but it offers important lessons about DNSSEC. more

Large Volume of DNSSEC Amplification DDoS Observed, Akamai Reports

A dramatic increase in DNS reflection/amplification DDoS attacks abusing Domain Name System Security Extension (DNSSEC) configured domains have been observed in the past few months, according to a security bulletin released by Akamai’s Security Intelligence Response Team (SIRT). more

Epsilon Interactive Breach the Fukushima of the Email Industry

A series of attacks on the Email Service Provider (ESP) community began in late 2009. The criminals spear-phish their way into these companies that provide out-sourced mailing infrastructure to their clients, who are companies of all types and sizes. ... On March 30, the Epsilon Interactive division of Alliance Data Marketing (ADS on NASDAQ) suffered a massive breach that upped the ante, substantially. Email lists of at least eight financial institutions were stolen. more

Spam Fighting: Lessons from Jack Bauer?

As I blogged about several months ago, as did numerous other anti-spam bloggers, David Ritz was sued by Jeffrey Reynolds and a judge in North Dakota agreed with Reynolds. At the heart of the case was that Ritz engaged in anti-spam activities using techniques known only to a small subset of advanced computer users, and used these techniques maliciously against Reynolds... Back in the olden days of spam fighting, some anti-spammers used to use malicious techniques against spammers in order to shut them down... more

World Body Declares Cyber Security Top Issue

Sovereign nations around the globe have clearly defined borders, but as attendees were shown at a UN Conference several years ago, cybercrime is a borderless phenomenon. In 2011 Norton Security released statistics that showed that every 14 seconds an adult is a victim of cybercrime and the numbers are growing. As internet use grows, so does the amount and type of information streaming across the web. This information crosses transnational lines, public and private sectors. more
