The installer unpacks the files to a folder.
alkasir.exe, alkasirB.dll, proxy.dll, servrlib.dll, ./ar/alkasir.resources.dll and ./en/alkasir.resources.dll are all .NET binaries.
I've been able to decompile these to C#.
Now, what would be the best course of action to share these amongst ourselves without disclosing it to the public?

Other than that, it contains alkasirS.exe which looks like a modified version of PuTTY with obfusction, called PoTTY; See:
libeay32.dll and ssleay32.dll look like OpenSSL 0.9.8k.
And the folder xulrunnner contains all sorts of binaries, which looks like a stock version of xulrunner 1.9.1.

Neat! Thanks for the help!

I know I asked the other night what tools/steps you took, but would you mind answering again, just so that we've got documentation here on the process?

Also, if you don't want to do the rest of the analysis, you could tarball what you've got so far and send it to me at isis(at)torproject(dot)org. My GPG key is 0x2CDB8B35, and I believe I've given you a card with my fingerprint. If you do still want to do the analysis, I'd be happy to meet with you somewhere and hack the rest of this out.

Shondoit and I reviewed the decompiled source last night and I was deaddropped a copy. Though, I should note that they did pretty much all the work and the analysis, and I just checked in every once in a while to ask questions and see how things were going. Most of the resulting information is Shondoit's discoveries, though I also went over the code to reconfirm.

The wiki page for Alkasir has been filled out with the notes from the review.

Shondoit, ioerror, hellais: do any of you have any additions or comments before I close this ticket?

And Shondoit: Thanks for all your help! You're awesome. :)
