Cybersecurity

In an Internet Minute

Intel sent an interesting infographic: What Happens in an Internet Minute. Looking at the traffic data, Intel asks if there is sufficient attention being paid to investment in infrastructure. Imagine the state of the network in three years, when the number of connected devices is projected to be double the world's population. Can our networks scale to handle predicted traffic and meet consumer expectations for immediate access from multiple devices? more

Cryptocurrency and DNS: Phishing Domains, Cryptomining and More

When we look at the intersection of cryptocurrency and domain data, we see something insidious: The prevalence of crypto-related threats. And it's not just cryptojacking. It's not even the use of cryptocurrency which has made ransomware attacks easier for threat actors to commit and all the more widespread. As with nearly every trend, there is always someone looking to capitalize on it and use it for their own, personal gain. Ever since cryptocurrency became the pandemic hobby of choice, threat actors have begun to target crypto novices for their schemes. more

DNSSEC Deployment Among ISPs: The Why, How, and What

It's no secret that Comcast has been leading the charge of DNSSEC deployment among ISPs. For the past couple years, Comcast has been testing and pushing for the widespread adoption of DNSSEC. In the spirit of increasing adoption, I thought I would interview the DNS gurus at Comcast to see what they've learned and what advice they would give other ISPs considering DNSSEC deployment. more

Clarke and Knake’s “Cyberwar”

I just finished reading Richard Clarke and Robert Knake's book Cyberwar. Though the book has flaws, some of them serious, the authors make some important points. They deserve to be taken seriously. I should note that I disagree with some of my friends about whether or not "cyberwar" is a real concept. Earlier, I speculated that perhaps it might be a useful way to conduct disinformation operations, but it need not be so limited. more

The DNSSEC Industry Coalition Meets to “Make It So”

The DNSSEC Industry Coalition conducted its first face to face meeting on Friday, March 13, 2009 at Google's Washington, DC office. Google's fun filled meeting room was packed with organizations that share a keen interest in DNS Security through the implementation of DNSSEC. more

Terrorism, New gTLDs, DAG4, and ICANN’s Continued US and Western Centric Bias

Those who have been involved in the ICANN process as long as I have naturally become accustomed to ICANN controversies at all levels. But the latest is a "wrong" of international ramifications. The four (4) versions of the Guidebook for the new generic Top-Level Domains (gTLDs) have been hundreds of pages long with a lot of The Good, The Bad, and to some, The Ugly. However, something new has appeared in the 4th and latest version called DAG4 can be called: "The Disturbing". more

New Chapter Working Groups Open Closed Doors

One thing was clear from a recent presentation by the new leaders of the SF-Bay Internet Society (ISOC) Chapter Working Groups: inclusion and collaboration will be the key to these groups' success. As Dr. Brandie Nonnecke, the Internet Governance Working Group (WG) Chair said, "We haven't yet cracked the code on what 'multistakeholder' means." But that won't stop her and Dr. Jaclyn Kerr, the Data Protection, Privacy, and Security WG Chair, from trying. more

Nearly 1 Million IP Addresses Used by Attackers on a Single Target

According to a recent report by Akamai, an analysis of massive Account Takeover (ATO) attack campaigns, targeting two of its customers, revealed 1,127,818 different IPs were involved in the attacks. more

Namecoin Decentralized DNS Research

The holidays open up a block of time to catch up on "I meant to read that" bookmarks, RSS feeds, and all the favorited and forgotten tweets. I made it through 50 before a NormanShark blog post kicked off a research project. The analysts found a malware sample which was using .bit domains in their communications infrastructure, but .bit ... what is that? .bit is a TLD operating outside of ICANN. Some would say they are TLD squatting, but I leave that opinion up to the reader. more

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

The Growing Threat of Cybersquatting in the Banking and Finance Sector

The apparent cyber heist of of $81 million from the Bangladesh central bank's U.S. account may cause some people to question the security of online banking. While the online theft prompted SWIFT - a cooperative owned by 3,000 financial institutions around the world -- to make sure banks are following recommended security practices, the incident also could have ramifications for banking customers worldwide. more

CNN Spam Outbreak Quickly Morphing Into a New Breed

This past week we have been seeing some heavy CNN spam -- that is, spam in the form of breaking news stories from CNN.com... These all look like legitimate news stories, and indeed, they probably are taken straight from an actual CNN news bulletin (I don't subscribe so I wouldn't know). Indeed, the unsubscribe information and Terms of Use actually link to actual CNN unsubscribe pages. However, if you mouse-over all of the news links, they go to a spam web page wherein the payload is either a spam advertisement or you click on another link to download a file and flip your computer into a botnet. more

Edge Computing, Fog Computing, IoT, and Securing Them All

The oft used term "the Internet of Things" (IoT) has expanded to encapsulate practically any device (or "thing") with some modicum of compute power that in turn can connect to another device that may or may not be connected to the Internet. ... The information security community -- in fact, the InfoSec industry at large -- has struggled and mostly failed to secure the "IoT". This does not bode well for the next evolutionary advancement of networked compute technology. 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

UN and Cybersecurity: Searching for Consensus in a Divided World

The 78th UN General Assembly (UNGA) addressed the issue of cybersecurity again at one of its last meetings in December 2023. It included the adoption of four resolutions on the Open-Ended Working Group (OEWG), a "Program of Action" (POA), and autonomous weapon systems. The texts of the four draft resolutions were negotiated in UNGA's 1st committee, responsible for international security issues, in October and November 2023. more
