Hacking Robots Before Skynet

Robots are going mainstream in both private and public sectors – on military missions, performing surgery, building skyscrapers, assisting customers at stores, as healthcare attendants, as business assistants, and interacting closely with our families in a myriad of ways. Robots are already showing up in many of these roles today, and in the coming years they will become an ever more prominent part of our home and business lives. But similar to other new technologies, recent IOActive research has found robotic technologies to be highly insecure in a variety of…

Vulnerability disclosure the good and the ugly

I can’t believe I continue to write about disclosure problems. More than a decade ago, I started disclosing vulnerabilities to vendors and working with them to develop fixes. Since then, I have reported hundreds of vulnerabilities. I often think I have seen everything, and yet, I continue to be surprised over and over again. I wrote a related blog post a year and a half ago (Vulnerability bureaucracy: Unchanged after 12 years), and I will continue to write about disclosure problems until it’s no longer needed.   Everything is…

Hacking Washington DC traffic control systems

This is a short blog post, because I’ve talked about this topic in the past. I want to let people know that I have the honor of presenting at DEF CON on Friday, August 8, 2014, at 1:00 PM. My presentation is entitled “Hacking US (and UK, Australia, France, Etc.) Traffic Control Systems”. I hope to see you all there. I’m sure you will like the presentation. I am frustrated with Sensys Networks (vulnerable devices vendor) lack of cooperation, but I realize that I should be thankful. This…

Hacking US (and UK, Australia, France, etc.) Traffic Control Systems

Probably many of you have watched scenes from “Live Free or Die Hard” (Die Hard 4) where “terrorist hackers” manipulate traffic signals by just hitting Enter or typing a few keys. I wanted to do that! I started to look around, and while I couldn’t exactly do the same thing (too Hollywood style!), I got pretty close. I found some interesting devices used by traffic control systems in important US cities, and I could hack them 🙂 These devices are also used in cities in the UK, France, Australia, China, etc.,…

At IOActive Labs, I have the privilege of being part of a great team with some of the world’s best hackers. I also have access to really cool research on different technologies that uncovers security problems affecting widely used hardware and software. This gives me a solid understanding of the state of security for many different software and hardware devices, not just opinions based on theories and real life experience.   Currently, the term Internet-of-Things (IoT) is becoming a buzzword used in the media, announcements from hardware device manufacturers, etc….

Practical and cheap cyberwar (cyber-warfare): Part II

Disclaimer: I did not perform any illegal attacks on the mentioned websites in order to get the information I present here. No vulnerability was exploited on the websites, and they are not known to be vulnerable.   Given that we live in an age of information leakage where government surveillance and espionage abound, I decided in this second part to focus on a simple technique for information gathering on human targets. If an attacker is targeting a specific country, members of the military and defense contractors would make good human…

Practical and cheap cyberwar (cyber-warfare): Part I

Every day we hear about a new vulnerability or a new attack technique, but most of the time it’s difficult to imagine the real impact. The current emphasis on cyberwar (cyber-warfare if you prefer) leads to myths and nonsense being discussed. I wanted to show real life examples of large scale attacks with big impacts on critical infrastructure, people, companies, etc.   The idea of this post is to raise awareness. I want to show how vulnerable some industrial, oil, and gas installations currently are and how easy it is…

NCSAM – an Interview with Cesar Cerrudo

Today we continue our support for National Cyber Security Awareness Month, by interviewing Cesar Cerrudo, Chief Technology Officer for IOActive Labs. Cesar provides us with some insight of how he got into IT security and why it’s important to be persistent! IOActive: How did you get into security?   Cesar: I think my first hacks were when I was 10 years old or so. I modified BASIC code on CZ Spectrum games and also cheated games by loading different parts of the code from a cassette (yes not…

Vulnerability bureaucracy: Unchanged after 12 years

One of my tasks at IOActive Labs is to deal with vulnerabilities; report them, try to get them fixed, publish advisories, etc. This isn’t new to me. I started to report vulnerabilities something like 12 years ago and over that time I have reported hundreds of vulnerabilities – many of them found by me and by other people too. Since the early 2000’s I have encountered several problems when reporting vulnerabilities: Vendor not responding Vendor responding aggressively Vendor responding but choosing not to fix the vulnerability Vendor releasing flawed patches…
