Jump List Forensics: AppIDs Part 2

In Part 1 of the Jump List Forensics AppID series, we took a look at what a Jump List essentially is and focused upon the AppIDs of the following types of software:
  • Internet Browsers
  • Image/Document Viewers
  • Media Players
  • Utilities
Now, in Part 2, we will close out the series by taking a look at the AppIDs for the following types of software:
  • File Sharing/P2P
  • FTP
  • IRC
  • IM/Communications
  • Usenet Newsreaders
  • System Cleaners
As you'll see in a bit, this round yielded many more results than the first. There were some other discoveries made along the way, as well. But before we get into all of that, let's recap what we know so far.

Jump List for CCleaner

Recap
  • Jump Lists provide artifacts regarding Most Recently Used (MRU) and/or Most Frequently Used (MFU) files/tasks/URLs for applications
  • AppIDs are calculated by Windows unless the application developer provides a custom AppID
  • Location from whence an executable was run matters in calculating the AppID (but don't disregard portable apps!)
  • Jump List artifacts for an application stay on the machine after said application is uninstalled
  • Per Harlan's post, MiTeC's SSViewer and Mark Woan's JumpLister can parse autoDest files
  • Jump Lists look like this, this, this, and this.

Jump List AppIDs

All applications are 32-bit. Tested on Windows 7 Professional SP1.

Note: Several versions of the same application were tested in many cases; just because it's the same application doesn't mean it will have the same AppID.

Caveats/Discoveries

Portable Applications
Throughout my testing, there were quite a few cases in which an AppID couldn't be identified on account of the application in question being "portable." Of course, what I mean by this is that the application was not bundled through an installer; instead, all of the configuration files/libraries were contained within a compressed archive upon download. It should be made clear that this is by no means a reason to disregard these applications. Just because an application is portable doesn't rule out the potential of finding and tracing its Jump List files. The fact that you know the application is portable is a step in the right direction. And as I mentioned in Part 1, there are solutions for the portable application "problem."

On that note, if you discover an AppID that is not found within these lists or ForensicsWiki list, be sure to parse the autoDest files instead of tossing it aside and deeming it insignificant. I say this because, as lengthy as these lists are getting, they are still far from complete. There's a lot of information out there on parsing and analyzing the Jump List files themselves, so finding out to which application the evidence AppID belongs -- without an AppID reference list -- is most certainly possible.

Multiple Version Testing
I noted this before, but there were many instances in which multiple versions of the same application were tested and documented. The reason for this was that some applications -- especially long-running and prevalent ones -- experience huge changes throughout their development cycles. A version jump could make a huge difference in how the application runs or is built. With that said, a version jump might cause an AppID alteration. If you look through the list, the evidence for this is pretty clear; different versions yield different AppIDs. This isn't always the case, but it does happen on occasion. I made sure to test as many versions of the applications as I could to see whether or not version changes affected the AppID. The results varied; some changed with every version jump (e.g. WiseFTP) while others stayed consistent throughout every release (e.g. BitSpirit).

AppID Length
Speaking of AppID analysis, I noticed that not all AppIDs share the same character length. For example, Skype yielded a 16-character AppID (521a29e5d22c13b4) while Paint 6.1 SP1 and Shareaza 8 yielded 15-character AppIDs (b3f13480c2785ae and b48ce76eda60b97, respectively). There were even a few that were 13 characters in length, believe it or not (AIM 7.5.11.9 - 6f647f9488d7a and fulDC 6.78 - 98b0ef1c84088). The reason I'm mentioning this is because I had remembered reading somewhere that the AppID was always 16-characters in length. It turns out that this was written in Alex Barnett's "Forensic Value of Windows 7 Jump Lists." It states:
Jump List file names, while appearing to be a random string of characters, always follow the format 16 characters dot automaticDestinations-ms or customDestinations-ms...
This is inaccurate, as shown by the many < 16-character AppIDs in the above lists. While the majority of AppIDs are 16-characters in length, not all of them are. Don't get me wrong, though -- Alex's writeup is phenomenal and well worth a focused read. It was one of the pioneer articles about Jump List forensics and details how one can discover whether or not illegal images were uploaded or downloaded based off of Jump List artifacts. Be sure to check it out; the above quote is the only thing that even came close to bothering me about the writeup.

Hover Menu + Fun Discoveries
Another thing I noticed throughout my testing was that it was common for IM clients and media players to pop up a little "available status" or music playback bar upon hovering over the taskbar icon. As far as I could tell, there was no Jump List file activity upon performing this action, but it's good to note based on the fact that almost every application that had this feature also had full Jump List support (showed MRUs/MFUs/Tasks).

Here's yet another fun little piece of testing treasure I found: one application was actually aware that it was running inside of a virtual machine and refused to install as a result. Stubborn! Though, it makes you wonder how sophisticated some malware might be if IM clients can detect living inside of a VM...

Yet ANOTHER odd bit that came from the testing session was the fact that Bearshare, iMesh, Shareaza, and Lphant are all pretty much exactly the same application save the color scheme and name label swap. I made an animated gif to illustrate.

Reverse Engineering IM Protocols
Finally, the last discovery made was that of IMfreedom.org. I actually stumbled upon that on accident in my quest to find more IM clients. A wiki for reverse engineering IM protocols is hosted there; it is tremendously detailed. Neat stuff.

Conclusion


There was some interesting discussion about what should be the main goal for future Jump List forensics. Jamie L suggested that the algorithm behind the Windows AppID calculation should be defined -- something with which I completely agree. Being able to calculate an AppID on the fly based on known conditions would make things a whole lot easier and much more efficient. It's just a matter of getting to that point and being able to make use of the process by which it's done.

UPDATE 4/30/13  If you haven't looked at @Hexacorn's blog post on AppID and Jumplist filename calculation, be sure to look at it. It sheds light on the way AppIDs are calculated.

It's been great to see so much activity regarding Jump List forensics recently. But as with many other pieces of forensic goodness, it could use some more research. Whether it's analyzing the AppID calculation algorithm or adding to the growing AppID reference list, any development is much appreciated. There will always be new software releases, so that list is bound to grow. The key point to take away from this, however, is that with more software comes more avenues for forensic analysis -- not only in terms of Jump Lists, but in general. There will never be a shortage of applications to analyze. I think Kazaa said it best, and I'm sure digital forensics analysts worldwide are excited to acknowledge this fact. I know I am.
