U.S. CERT Issues Alert on DNS Amplification Attacks

Neil Schwartzman writes to report that U.S. Cert issued Alert TA13-088A on Friday March 29, 2013. "It is a solid how-to guide to test for, and remediate DNS configurations that can be used for Distributed Denial of Service attacks." more

The Militarization of the Internet

Someone needs to take a good hard look at those Internet surveillance stories being strategically placed on the front page of the New York Times. There's a trail here, I believe, that's worth following. Here are some data points... there appears to be a deep interest in the ability to declare war online, as evidenced by cybersecurity research and public speeches by Herbert Lin, a key player who has worked on several cybersecurity reports for the National Research Council.

Researches Demonstrate How IPv6 Attacks Can Bypass Network Intrusion Detection Systems

With the increasing popularity of IoT devices and the added interest of transition to IPv6, a whole new range of threat vectors are evolving that allow attackers to set up undetectable communications channels across networks. more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

Researchers Use Social Graphs to Detect Spammers, Attackers

A project named S-GPS or Spammer Global Positioning System, by Microsoft researchers uses spammer identification rather than spam identification to identify zombie-based spammers. more

What Next for Email Service Providers?

It's been a very bad month for ESPs, companies that handle bulk mailings for their clients. Several of them have had internal security breaches, leaking client information, client mailing lists, or both. Many have also seen clients compromised, with the compromised credentials used to send spam. The sequence of events suggests all the ESPs whose clients were compromised were themselves compromised first. (That's how the crooks knew who to attack.) 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

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

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

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

Hackers Use Tesla’s Amazon Cloud Account to Mine Cryptocurrency

Tesla's cloud environment has been infiltrated by hackers and used to mine cryptocurrencies, researchers have discovered. Other victims include Aviva and Gemalto. more

Strange Email Used to Inform Marriott Customers About the Massive Data Breach

Millions of email warnings were sent out by Marriot on Friday to warn customers about the massive data breach which has affected close to half a billion guest data. 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
