Exploiting Industrial Collaborative Robots
Traditional industrial robots are boring. Typically, they are autonomous or operate with limited guidance and execute repetitive, programmed tasks in manufacturing and production settings.1 They are often used to perform duties that are dangerous or unsuitable for workers; therefore, they operate in isolation from humans and other valuable machinery. This is not the case with the latest generation collaborative robots (“cobots”) though. They function with co-workers in shared workspaces while respecting safety standards. This generation of robots works hand-in-hand with humans, assisting them, rather than just performing automated, isolated operations. Cobots can learn movements, “see” through…
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…
Five Attributes of an Effective Corporate Red Team
After talking recently with colleagues at IOActive as well as some heads of industry-leading red teams, we wanted to share a list of attributes that we believe are key to any effective Red Team. [ NOTE: For debate about the relevant terminology, we suggest Daniel’s post titled The Difference Between Red, Blue, and Purple Teams. ] To be clear, we think there can be significant variance in how Red Teams are built and…
Inside the IOActive Silicon Lab: Interpreting Images
In the post “Reading CMOS layout,” we discussed understanding CMOS layout in order to reverse-engineer photographs of a circuit to a transistor-level schematic. This was all well and good, but I glossed over an important (and often overlooked) part of the process: using the photos to observe and understand the circuit’s actual geometry. Optical Microscopy Let’s start with brightfield optical microscope imagery. (Darkfield microscopy is rarely used for semiconductor work.) Although reading lower metal layers on modern deep-submicron processes does usually require electron microscopy, optical microscopes still have…
Red Team Testing: Debunking Myths and Setting Expectations
The term “cyber” seems to be overused in every corner of the information security industry. Now there is a new buzz phrase in computer security, “red team engagements.” Supposedly (to get “cyber” on you), you can have a red team test, and it will help move your organization in the correct “cyber direction.” But what is red team testing really? And what is it not? In this post I’ll try to make some sense of this potent term. The red team concept has been around for ages. It…
Tools of the Trade – Incident Response, Part 1: Log Analysis
There was a time when I imagined I was James Bond zip lining into a compromised environment, equipped with all kinds of top-secret tools. I would wave my hands over the boxes needing investigation, use my forensics glasses to extract all malware samples, and beam them over to Miss Moneypenny (or “Q” for APT concerns) for analysis. I would produce the report from my top-notch armpit laser printer in minutes. I was a hero. As wonderful as it sounds, this doesn’t ever happen in real life. Instead of sporting a…
SQL Injection in the Wild
As attack vectors go, very few are as significant as obtaining the ability to insert bespoke code in to an application and have it automatically execute upon “inaccessible” backend systems. In the Web application arena, SQL Injection vulnerabilities are often the scariest threat that developers and system administrators come face to face with (albeit way too regularly). In fact the OWASP Top-10 list of Web threats lists SQL Injection in first place. More often than not, when security professionals…
The Demise of Desktop Antivirus
Are you old enough to remember the demise of the ubiquitous CompuServe and AOL CD’s that used to be attached to every computer magazine you ever brought between the mid-80’s and mid-90’s? If you missed that annoying period of Internet history, maybe you’ll be able to watch the death of desktop antivirus instead. 65,000 AOL CD’s as art Just as dial-up subscription portals and proprietary “web browsers” represent a yester-year view of the Internet, desktop antivirus is similarly being confined…
Exploits, Curdled Milk and Nukes (Oh my!)
Throughout the second half of 2012 many security folks have been asking “how much is a zero-day vulnerability worth?” and it’s often been hard to believe the numbers that have been (and continue to be) thrown around. For the sake of clarity though, I do believe that it’s the wrong question… the correct question should be “how much do people pay for working exploits against zero-day vulnerabilities?” The answer in the majority of cases tends to be “it depends on who’s buying and what the vulnerability is” regardless of the…
Atmel AT91SAM7S Overview
Atmel produces a number of ARM based devices in their portfolio of products. We had one laying around the lab so here we go as usual… The device was a 48 pin QFP type package. We also purchased a sample of the other members of the family although the initial analysis was done on the AT91SAM7S32 part shown above. All pictures will relate to this specific part even though there is not a signifigant difference between the other members of this line except memory sizes. After decapsulating the die from…
