Ok now that we have showed you how to bypass authentication on a Toshiba eStudio MFP device. The next obvious step is what data can be extracted. Well it turns out that the Toshiba eStudio multifunction printers also leaks data. If you examine the HTML source code of any of the configuration pages you will find the passwords in plan text. Yes that ******* in the password configuration setting field is not really hiding anything.

PercX will being speaking on printers, and embedded device information gathering attacks. Covering how the information is leveraged to gain access to other core network server systems. Also will be discussing the tool Praeda and its features, functions, and future. So join PercX at BSides Delaware. Registration is available here and schedule information is available here.

I’ve posted an updated version of my “Karma” patch for HostAP (hostap_0_7_2-775-g9fc6aa9). This patch adds Karma-style automatic probe response, in addition to PEAP/MSCHAPv2 authentication logging (think all-in-one FreeRadius-WPE). See the Wireless page for a link to the old Hostap 0.6.9 patch and the newer version.

PercX has been furiously hacking multi-function printers, and the result is a new tool called Praeda. Praeda is used to interrogate printers from a variety of manufacturers in an effort to gain information about a target network, or compromise credentials. You can get it here. It’s written in perl.

Required perl modules:



TARGET_FILE = List of IP addresses or Host names to enumerated
TCP_PORT = port address of targets to scan ” At present only one port can be specified. This is expected to be modified in future version”
PROJECT_NAME = the name for this project. This will create a folder under the folder where Praeda was executed to contain logs and export info.
OUTPUT_FILE = name of log file for data output

./praeda.plĀ  target.lst 80 project1 data-file

The results will create a folder called project1 and save all information in that folder. Praeda will also create a log file called data-file.log to store output and diagnostics.


I reworked the site a bit yesterday. My goal is to migrate all of my old patches/content into it. You’ll find a couple of new pages (Passwords & Hashes, Challenge/Response Authentication) linked on the right sidebar. These pages should contain the latest Samba and other patches I’ve put together over the years.

I’ve also added a new wireless page which contains a patch to Hostapd that adds auto-probe response and PEAP/MSCHAPv2 logging fun.
