Designed as a SaaS, iKAT features many methods of escaping out of a browser jailed environment and gaining command execution. iKAT is a website you visit from a Kiosk, its quick, free, and aims to please.

Defcon 18 Edition:
———————
iKAT and Defcon seem to go hand in hand, and when the con is on Kiosks get ‘visited’ by iKAT. Traffic to the iKAT website increased by 10x last year during Defcon 17! To celebrate this, the author has released iKAT v3, and included a limited edition Defcon skin.

Whats New in iKAT v3:
———————-

* Signed Code
All iKAT tools, VBScripts, ActiveXs, ClickOnce, SilverLight apps are now signed by a trusted CA!
Four months ago i placed a “Donate Now” button on the front page of iKAT, hoping to raise money for a code signing certificate
Sadly only two people donated cash (Enrique Exposito Martinez and Gerald Fehringer, you guys rock)
Luckily a Kiosk vendor was willing to come to the party and donate the remaining cash, so iKAT can get signed.
Big thanks to Kioware Kiosks, who kindly donated the remaining money.
All iKAT tools are now signed by a trusted CA

* More Tools
iKAT now contains more tools packaged in different containers, file formats, PDFs, and even silent installers.
More Java Applets, More VBScript, More WMI!

* iKAT ActiveX
A newly developed ActiveX which focuses on Windows Shell hacking and process spawning.
The ActiveX is signed and provides a mad amount of functionality.

* iKAT OfficeKAT
Thanks to Didier Stevens who donated his “Excel Spawn CMD in Memory” trick to the iKAT project
OfficeKAT allows you to pop shell in environments where you can run Excel, what’s more you don’t need to write to the file system.

* iKAT SilverLight
SilverLight (and mono) are now supported by iKAT, and provide yet another attack vector for your pleasure

* Improved URI + File Handler Enumeration
Vastly improved enumeration code, more URI’s, more instant “One click magic”. I also added support some of the more interesting Microsoft based URI handler vulnerabilities released this year.

* Emo Kiosking – Crashing the Kiosk
The fastest way to get out of a browser jail environment is to simply CRASH IT.
Oddly enough this is also the easiest thing to do to a browser, and Emo-Kiosking has become a personal favourite trick of mine.
iKAT now supports over 60 different methods of crashing a browser, or a browser add-on
This allows you to quickly drop back to the desktop, often with only one click required.

We are in the testing phase of iKat so cannot comment much on this tool. We will keep you posted.

A simple tool designed to help out with crash analysis during fuzz testing. It selectively “un-fuzzes” portions of a fuzzed file that is known to cause a crash, re-launches the targeted application, and sees if it still crashes. Eventually, this will yield a file that still causes the crash, but contains a minimum set of changes from the original un-fuzzed file.

How does fuzzdiff works

When provided with a fuzzed file, a corresponding original un-fuzzed
file, and the path to the targeted program, FuzzDiff will selectively “un-fuzz” portions of the fuzzed file while re-launching the application to monitor for crashes. This will yield a file that still crashes the target application, but contains a minimum set of changes from the original, un-fuzzed file. This can be useful in pinning down the exact cause of a crash.

The tool is written in Python and currently only works on Unix-based systems, since it monitors for crashes by checking for SIGSEGV. It also assumes that the target program adheres to the syntax “[program] [args] [input file]“. Both of these limitations can be easily worked around. The code is hardly what I’d call production-ready, but it gets the job done.

FuzzDiff will help to analysis and find the root cause analysis of problem and fine tune our fuzz method

We have talked about fuzzdb in detail here. Now, it has been updated to version 1.08!

fuzzdb helps identify security flaws in applications by aggregating known attack patterns, predictable resource names, and server response messages to create a comprehensive, repeatable set of malformed input test cases.

dreamstime 9446764 UPDATE: fuzzdb v1.08!

This update, with many changes fuzzdb helps identify security flaws in applications by aggregating known attack patterns, predictable resource names, and server response messages to create a comprehensive, repeatable set of malformed input test cases.
