The Take Away from Global Payments Breach

Global Payments, an Atlanta-based payment card processing firm, announced yesterday that they had suffered "unauthorized access into a portion of its processing system". Sometime in early March they uncovered the attack, and there are some indications that the breach occurred between January 21st and February 25th of this year... There are a number of unverified reports that a New York City street gang with Central American ties took control of "an administrative account that was not protected sufficiently". more

An Astonishing Collaboration

Wow. It's out. It's finally, finally out... So there's a bug in DNS, the name-to-address mapping system at the core of most Internet services. DNS goes bad, every website goes bad, and every email goes...somewhere. Not where it was supposed to... I'm pretty proud of what we accomplished here. We got Windows. We got Cisco IOS. We got Nominum. We got BIND 9, and when we couldn't get BIND 8, we got Yahoo, the biggest BIND 8 deployment we knew of, to publicly commit to abandoning it entirely. It was a good day... more

Coordinating Attack Response at Internet Scale

How do we help coordinate responses to attacks against Internet infrastructure and users? Internet technology has to scale or it won't survive for long as the network of networks grows ever larger. But it's not just the technology, it's also the people, processes and organisations involved in developing, operating and evolving the Internet that need ways to scale up to the challenges that a growing global network can create. more

Internet Infrastructure: Stability at the Core, Innovation at the Edge (Part 2 of 5)

For nearly all communications on today's Internet, domain names play a crucial role in providing stable navigation anchors for accessing information in a predictable and safe manner, irrespective of where you're located or the type of device or network connection you're using. Over the past 15 years hundreds of millions of domain names have been added to the Internet's Domain Name System (DNS), and well over two billion (that's Billion!) new users, some ~34 percent of the global population, have become connected. more

Mitigating the Increasing Risks of an Insecure Internet of Things

The emergence and proliferation of Internet of Things (IoT) devices on industrial, enterprise, and home networks brings with it unprecedented risk. The potential magnitude of this risk was made concrete in October 2016, when insecure Internet-connected cameras launched a distributed denial of service (DDoS) attack on Dyn, a provider of DNS service for many large online service providers (e.g., Twitter, Reddit). Although this incident caused large-scale disruption, it is noteworthy that the attack involved only a few hundred thousand endpoints... more

Hyper-Volumetric DDoS Attack Sets New Benchmark at 22.2 Tbps

A record-shattering DDoS attack peaking at 22.2 Tbps signals a new era of cyber aggression, driven by weaponized IoT botnets and raising urgent questions about global internet resilience. more

Phish or Fair?

It shouldn't be a big surprise to hear that phishing is a big problem for banks. Criminals send email pretending to be a bank, and set up web sites that look a lot like a bank. One reason that phishing is possible is that e-mail has no built in security, so that if a mail message comes in purporting to be from, say, [email protected], there's no easy way to tell whether the message is really from bankofamerica.com, or from a crook. more

Facebook Apps on Any Website: A Clever Move? Or a Security Nightmare?

Well, given the amount of malicious JavaScript, malware, and other possibilities to use Facebook (and other similar social networking platforms) for abuse, I certainly wouldn't categorize this news as a "clever move"... In fact, I foresee this as an extraordinarily short-sighted move with far-reaching security implications -- which will allow the levels of malicious abuse to reach new heights. more

Should You Whitelist Your Vulnerability Scanning Service Provider?

Unlike consultant-led penetration testing, periodic or continual vulnerability scanning programs have to operate harmoniously with a corporation's perimeter defenses. Firewalls, intrusion prevention systems, web proxies, dynamic malware analysis systems, and even content delivery networks, are deployed to protect against the continuous probes and exploit attempts of remote adversaries -- yet they need to ignore (or at least not escalate) similar probes and tests being launched by the managed security service providers an organization has employed to identify and alert upon any new vulnerabilities within the infrastructure or applications that are to be protected. more

The Report on “Securing Cyberspace for the 44th Presidency”

A report "Securing Cyberspace for the 44th Presidency" has just been released. While I don't agree with everything it says (and in fact I strongly disagree with some parts of it), I regard it as required reading for anyone interested in cybersecurity and public policy. The analysis of the threat environment is, in my opinion, superb; I don't think I've seen it explicated better. Briefly, the US is facing threats at all levels, from individual cybercriminals to actions perpetrated by nation-states. The report pulls no punches... more

Searching for Truth in DKIM: Part 2 of 5

In part 1, we explained that the DKIM "d=" value identifies the domain name which signed the message, which may be a different domain name from the author of the message. Tying the signing and author domains together will require an additional standard: Author Domain Signing Practices (ADSP). In IETF parlance, the "author domain" is the domain name in the From: header, so ADSP is a way for the author domain to publish a statement specifying whether any other domain name should ever sign a message purporting to be From: that author domain... more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

Fixing the Internet Might Break It Worse Than It’s Broken Now

Willis Alan Ramsey, who wrote "Muskrat Love," recorded one and only one studio album. The cognoscenti of country think it's a gem, an all time top ten. There's an apocryphal story that when Ramsey was pushed to make another record he allegedly retorted, "What's wrong with the first one?" We who use the Internet every day risk losing sight of what a miracle it is, and the openness that keeps it so miraculous... We also lose sight of the fact that even as the Internet's miracles occur, it's almost always broken or malfunctioning or threatening or worse in many places along the line. more

Security Firm Recovers Over 272 Million Stolen Credentials from a Collector

The latest discovery came while researchers at a security firm found a young Russian hacker bragging in an online forum that he had collected and was ready to give away a far larger number of stolen credentials that ended up totalling 1.17 billion records, Reuters reports. more

Internet Security and the Multistakeholder Approach: Is It Attainable?

Internet Security is a topic that has drawn a lot of attention over the past year. As awareness grows that cooperation is necessary, it dawns on people that there are many and very different stakeholders involved, stakeholders that may never have met before. Let alone have cooperated. An example of an approach is the National Cyber Security Council (NCSC) that was installed in The Netherlands on 30 June. This is a high level council that will give advice to public as well as private entities on how to better secure themselves and society at large against cyber attacks and how to become more resilient. However, without the right approach it is doomed to become a talking shop. more
