Dell Loses Key Customer Support Domain Name for a Month, Site Exposed to Questionable Content

The website designated by Dell Inc. to help customers recover from malicious software and other computer maladies may have been hijacked for a few weeks this summer by people who specialize in deploying said malware, reports Brian Krebs in KrebsOnSecurity. more

Phishing: Competing on Security

The UK today is one of the main attack targets by phishing organized crime groups, globally. Phishing damages will amount to about two billions USD in 2006 worldwide -- not counting risk management measures such as preventative measures, counter-measures, incident response and PR damages. In most cases, phishing is caused by the fault of the users, either by entering the wrong web page, not keeping their computers secure or falling for cheap scams. Often this is due to lack of awareness or ability in the realm of Internet use rather than incompetence by the users... more

How to Choose a Cyber Threat Intelligence Provider

Throughout the course of my career I've been blessed to work with some of the most talented folks in the security and cyber threat intelligence (CTI) mission space to create a variety of different capabilities in the public, private and commercial sectors. Before I came to lead the Verisign iDefense team about five years ago, I had to evaluate external cyber-intelligence vendors to complement and expand the enterprise capabilities of my former organization. more

Thailand has Become the World’s Leading Hotspot for Cryptocurrency Mining Malware

New research indicates Thailand as being the world's number one hotspot for cryptocurrency mining malware. more

DNS Privacy at IETF 104

From time to time the IETF seriously grapples with its role with respect to technology relating to users' privacy. Should the IETF publish standard specifications of technologies that facilitate third-party eavesdropping on communications or should it refrain from working on such technologies? Should the IETF take further steps and publish standard specifications of technologies that directly impede various forms of third party eavesdropping on communications? more

Bell Canada Discloses Loss of 1.9 Million Email Addresses to Hacker, Says No Relation to WannaCry

Bell Canada, nation’s largest telecommunications company, disclosed late on Monday the illegal access of Bell customer information by an anonymous hacker. 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

Cyberattack Causes Operational Disruption to Critical Infrastructure Using New Malware TRITON

A new malware designed to manipulate industrial safety systems was deployed against a critical infrastructure organization that provides emergency shutdown capability for industrial processes, according to a report released today. 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

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

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

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

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
