Brazil: The Newest Up and Comer

The Virus Bulletin Conference last month had some good presentations, including this one by Fabio Assolini of Kaspersky. He spoke about how Brazil is the the newest up-and-comer on the cyber crime block. The tale begins with the story of Igor and Emily, two cyber criminals operating out of Brazil. Together, the two of them stole $300,000 US from a single Brazilian bank in one year. more

Water Supply System Apparently Hacked, with Physical Damage

According to press reports, a water utility's SCADA network was hacked. The attacker turned a pump on and off too much, resulting in physical damage to the pump. ... For years, security specialists have been warning that something like this could happen. Although more and more people have started to believe it, we still hear all of the usual reassuring noises -- the hackers don't know enough, we have defenses, there are other safeguards, etc. That debate is now over... more

Taking the Leap to Cloud-Based Malware Inspection

Is desktop anti-virus dead? Someday I'd love to make that announcement, but it still feels to me that there's a Patron Saint of Voodoo with an affinity for bringing it back to life -- like some macabre mirror image of the malicious zombies it's supposed to provide protection against. It's kind of ironic that today's innovation in desktop anti-virus isn't really happening at the desktop; rather it's occurring in the cloud. more

The Sins of the Flash

Recent news stories (based on research by Stanford student Feross Aboukhadijeh) state that an Adobe bug made it possible for remote sites to turn on a viewer's camera and microphone. That sounds bad enough, but that's not the really disturbing part. more

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
