Breaking

Almost every higher class DSLR on the market today features multiple and complex access technologies. To name a few, canons new flagship features IP connectivity wired via 802.3 as well as wireless via 802.11. All the big vendors are pushing these features to the market and advertise them with real time image transfer to the cloud. We have taken a look at the layer 2 and 3 implementations in the CamOS and the services running upon those, so here is what we found while examine the EOS 1D X:

Our new workshop about mobile application testing, held for the 1st time at the Troopers conference 2013, is coming closer. So I would like to take the opportunity and post an appetizer for those who are still undetermined if they should attend the workshop ;-).

While the topic of mobile application testing is a wide field that may contain reverse engineering, secure storage analysis, vulnerability research, network traffic analysis and so forth, in the end of the day you have to answer one question: Can I trust this application and run it on my enterprise devices? So first you have to define some criteria, which kind of behavior and characteristics of an application you regard as trustworthy (or not). Let us peek at malware … besides harming your devices and data, malware is typically:

This post tries to give an overview about the background and impact of the new Rails XML parameter parsing vulnerability patched today.

The bug

The root cause of the vulnerability is Rails handling of formatted parameters. In addition to standard GET and POST parameter formats, Rails can handle multiple different data encodings inside the body of POST requests. By default JSON and XML are supported. While support for JSON is widely used in production, the XML functionality does not seem to be known by many Rails developers.

Hi again and a happy new year 2013!

Lets continue were I left you the last time.

The CTL

The CTL is basically a binary TLV file with 1 byte type, followed by 2 bytes length and finally the data. But as this is far to easy, some special fields omit the length field and just place the data after the type (I guess those are fields with a fixed length). Here is an example CTL file:

Some of you may have heard the topic before, as we have spoken about on this years BlackHat Europe, TROOPERS12  and HES12, so this is nothing completely new, but as we’re done with responsible disclosure (finally (-; )  and all the stuff should be fixed, we’re going to publish the code that brought us there. I will split the topic into two blog posts, this one will wrap up the setup, used components and protocols, the next one [tbd. till EOY, hopefully] will get into detail on the tools and techniques we used to break the enterprise grade security.

Today is a great day, its the day, Loki finally runs on all big operating systems. Im proud to announce the first Loki release for Windows!

There are a few things not working (yet / at all) under Windows. Those are:

• The WLCCP Module – ive not yet managed to build and link against asleap on windows [but time may help (-; ]
• TCP-MD5 Auth for BGP – This will never work, as Windows has no TCP-MD5 impl. in the kernel
• The MPLS Module – Had some hassle here with WinPcap, may be working in the future

The most testing so far was done on Windows 7 were all the other functions work as they do on Linux and Mac.

Almost all of our presentations and write-ups on the VMDK File Inclusion Vulnerability contained a slide stating something like

“we’re rather sure that DoS is possible as well ;-)”

including the following screenshot of the ESX purple screen of death:

So it seems like we still owe you that one — sorry for the delay! However the actual attack to trigger this purple screen was rather simple: Just include multiple VMDK raw files that cannot be aligned with 512 Byte blocks — e.g. several files of 512 * X + [0 < Y < 512] Bytes. Writing to a virtual hard drive composed of such single files for a short amount of time (typically one to three minutes, this is what we observed in our lab) triggered the purple screen on both ESXi4 and ESXi5 — at least for a patch level earlier than Releasebuild-515841/March 2012: it seems like this vulnerability was patched in Patch ESXi500-201203201-UG.

Finally it’s here!

pytacle is a tool inspired by tentacle. It automates the task of sniffing GSM frames of the air, extracting the key exchange, feeding kraken with the key material and finally decode/decrypt the voice data. All You need is a USRP (or similar) to capture the GSM band and a kraken instance with the berlin tables (only about 2TB 😉 )

I’ve posted a preview before, take a look at the video to see the tool in action.

Microsoft takes this vulnerability quite serious and was acting fast. The Microsoft Security Response Center announced the availability of a fix last night in the MSRC Blog.

The fix will be available via Windows Update on friday, the 21st of september. So it’s time to get ready for this update ;-).

Have a nice day
Michael
