Wadi Fuzzer
“Operating system facilities, such as the kernel and utility programs, are typically assumed to be reliable. In our recent experiments, we have been able to crash 25-33% of the utility programs on any version of UNIX that was tested.” [1] Those were the original words in one of the first fuzzing studies where Prof. Barton Miller was first to use the term ‘fuzzing’ One can see the importance of fuzzing…
WiFi De-authentication Rifle:
Wireless: it’s everywhere these days and yet owning it never gets boring. As part of our annual SensePost hackathon, where we get time off projects and get to spend a week tinkering with tech and ideas, the team I was in, consisting of Dominic, Nathi and myself, decided on creating a wireless rifle de-authentication gun, which utilized a yagi antenna and a Raspberry Pi. The idea was simple: simulate some…
Release the hounds! Snoopy 2.0
Friday the 13th seemed like as good a date as any to release Snoopy 2.0 (aka snoopy-ng). For those in a rush, you can download the source from GitHub, follow the README.md file, and ask for help on this mailing list. For those who want a bit more information, keep reading. Snoopy is a distributed, sensor, data collection, interception, analysis, and visualization framework. It is written in a modular format,…
SenseCon 2014
What originally started as one of those “hey, wouldn’t this be cool?” ideas, has blossomed into a yearly event for us at SensePost. SenseCon is a time for all of us to descend on South Africa and spend a week, learning/hacking/tinkering/breaking/building, together and in person. A few years ago we made the difficult, and sometimes painful, shift to enable remote working in preparation for the opening of our UK and Cape Town…
January Get Fit Reversing Challenge
Aah, January, a month where resolutions usually flare out spectacularly before we get back to the couch in February. We’d like to help you along your way with a reverse engineering challenge put together by Siavosh as an introduction to reversing, and a bit of fun. This simple reversing challenge should take 4-10+ hours to complete, depending on your previous experience. The goal was to create an interactive challenge that…
BlackHat Conference: Z-Wave Security
We are publishing the research paper and tool for our BlackHat 2013 USA talk on the Z-Wave proprietary wireless protocol security. The paper introduces our Z-Wave packet interception and injection toolkit (Z-Force) that was used to analyze the security layer of Z-Wave protocol stack and discover the implementation details of the frame encryption, data origin authentication and key establishment process. We developed the Z-Force module to perform security tests against…
Analysis of Security in a P2P storage cloud
A cloud storage service such as Microsoft SkyDrive requires building data centers as well as operational and maintenance costs. An alternative approach is based on distributed computing model which utilizes portion of the storage and processing resources of consumer level computers and SME NAS devices to form a peer to peer storage system. The members contribute some of their local storage space to the system and in return receive “online backup and data…
Snoopy: A distributed tracking and profiling framework
At this year’s 44Con conference (held in London) Daniel and I introduced a project we had been working on for the past few months. Snoopy, a distributed tracking and profiling framework, allowed us to perform some pretty interesting tracking and profiling of mobile users through the use of WiFi. The talk was well received (going on what people said afterwards) by those attending the conference and it was great to…
44Con: Vulnerability analysis of the .NET smart Card Operating System
Today’s smart cards such as banking cards and smart corporate badges are capable of running multiple tiny applications which are often written in high level programming languages like Java or Microsoft .NET and compiled into small card resident binaries. It is a critical security requirement to isolate the execution context and data storage of these applications in order to protect them from unauthorized access by other malicious card applications. To satisfy…
RSA SecureID software token update
There has been a healthy reaction to our initial post on our research into the RSA SecureID Software Token. A number of readers had questions about certain aspects of the research, and I thought I’d clear up a number of concerns that people have. The research pointed out two findings; the first of which is in fact a design vulnerability in RSA software’s “Token Binding” mechanism. The second finding is…
