The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little. more

Typosquatting Continues to Pose Dangers to Enterprises, Consumers

While typosquatting is not a new phenomenon, recent research highlights that it is being used to collect sensitive corporate information from employees and lure consumers to interact with dubious websites. ... Security consultancy Godai Group recently uncovered the use of a specific type of typosquat - a "doppelganger domain" - to collect sensitive enterprise information via email-based attacks. more

Hacking Away at the Internet’s Security

The front page story of the September 13 2011 issue of the International Herald Tribune said it all: "Iranian activists feel the chill as hacker taps into e-mails." The news story relates how a hacker has "sneaked into the computer systems of a security firm on the outskirts of Amsterdam" and then "created credentials that could allow someone to spy on Internet connections that appeared to be secure." According to this news report this incident punched a hole in an online security mechanism that is trusted by hundreds of millions of Internet users all over the network. more

Internet: Government Dominance or Governance?

In an age where the world has gone global in many forms and guises, the political attention is more and more focussed on national, populist issues, that arise from fear for the unknown. I can't deny it: the future undoubtedly contains many uncertainties. This usually comes with a general public that's afraid and in fear of things they cannot oversee. Thus it is easily aroused by a populist leader who feeds on this fear and throws flammable material on the already smouldering fire. In a time where leadership is called for, it seems lacking. The Internet governance discussion demands visionary leadership on a cross border level and it needs it soon. more

The Rising Technical Challenges of Networking at Home

For me, one of the more interesting sessions at the recent IETF 81 meeting in July was the first meeting of the recently established Homenet Working Group. What's so interesting about networking the home? Well, if you regard challenges as "interesting", then just about everything is interesting when you look at networking in the home! more

Is Cybersecurity a Priority? You Wouldn’t Know It If You Go by Top Level Defections

In the US administration, we see important people like incoming Secretary of Defense Leon Panetta say at his Senate confirmation hearing that "a strong likelihood that the next Pearl Harbor" could well be a cyberattack that cripples the U.S. power grid and financial and government systems. He also said that cybersecurity will be one of the main focuses of his tenure at the Pentagon. But when you look at what is actually happening in cyber security, there is more position jockeying than there is real progress. 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

The ENISA Botnet Report: Thoughts on the State of Play in Smart Phones

At the ENISA presentation on her botnet report at eco in Cologne, 9 and 10 March, one of the slots was dedicated to threats to the mobile environment. The message I was supposed to come home with was: we can still count the numbers of mobile viruses manually, <600; the problem will never be the same as on a fixed network as traffic is monitored and metered: We detect it straight away. We are studying the problem seriously. Are mobile operators really prepared for what is coming? more

Report on Smart Grid Cyber Security

A recent report from Pike Research, "Smart Grid Cyber Security" has found if smart grids can realize their full potential, consumers, utilities, nations, and even the earth itself will benefit. As with nearly any new technology, the industry focus has been on getting smart grids up and running, often with little consideration for cyber security issues. more

Password Policies Need to Be the Same if We Want Users to Take Our Advice

The other day on Facebook, one of my friends mentioned that today (i.e., that day) was a good day to update his passwords. But he then lamented that some web sites don't allow you to create more than a 12-character password! He was incensed! Well, maybe not incensed but showed contempt for the fact these sites restricted password length. more

Defending Against the Hackers of 1995

Two factor authentication that uses an uncopyable physical device (such as a cellphone or a security token) as a second factor mitigates most of these threats very effectively. Weaker two factor authentication using digital certificates is a little easier to misuse (as the user can share the certificate with others, or have it copied without them noticing) but still a lot better than a password. Security problems solved, then? 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

Why the Fukushima Analogy Was Apt

A few days ago, CAUCE published a blog post entitled "Epsilon Interactive breach the Fukushima of the Email Industry" on our site, and the always-excellent CircleID. A small coterie of commenters was upset by the hyperbolic nature of the headline. Fair enough, an analogy usually has a high degree of probability that it will fail, and clearly, no one has died as a result of the release of what appears to be tens of millions of people's names and email addresses. But, the two situations are analogous in many other ways, and here's why. 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

Neelie Kroes, the EU, Cloud Computing, Regulation and Good Ears

In her blog EU Commissioner Neelie Kroes blogs on her stance on cloud computing. In short: this is a good development which the EU will embrace and advocate, but may need regulation in order to ensure a safe environment for industry and individuals in the cloud. Here's some thoughts on that. more
