I just started this one, and I've put together some really good notes already. I understand how the pages are linked and have drawn conclusions about various portions of the server's directory structure. My issue is a matter of access. So, in order to prevent me from blindly chasing rabbits here, is it at all possible to complete this mission without registering an account with SimpleMail? Namely, is it possible to gain account privileges, without going through the registration process? I don't need to know how it's done, just whether or not that functionality exists within this mission. I'm assuming the session handling is done by a specific module pushed by in***.p**, and that login could possibly be achieved by exploiting certain aspects of said module. I know that in a real world situation, I'd need to discover this for myself, which could take quite a long time, and loads of experimentation. But, based on the posts that have been written here, and the tutorial for this mission, my assumptions could lead me on a long and fruitless journey. I'm not really asking for a handout in this sense, just a little guidance. So, if this method of gaining access is just a dark alley, I'd like to know so that I'm not wasting my time. Thanks.
EDIT:
I just finished this one, following the method discussed here, and am still not 100% sure that I wasn't on the right path before. So, I'm still interested to know if there was an alternate method of gaining access. The mods and devs elude to the possibility, but I gave up on finding it once I saw a much simpler path. Perhaps somebody could send me a message hinting at an alternate solution. It would be worth trying a second time.
Here's a bit of info for those having trouble:
1. There is absolutely no need for a packet sniffer on this mission. That was probably the biggest misconception from the tutorial. However, now that I've completed the mission, I fully understand why it was suggested.
2. A Flash Decompiler isn't needed but it definitely cuts down on the experimentation time.
I saw that somebody asked for a good free one. flasm and flare did the job for me. Both are also cross platform as far as I know. And, they're good at what they do.
3. If you do decide to use a decompiler, put off using it until late in the mission, otherwise, you're just going to confuse yourself.
4. Overwriting that certain pain in the ass file, is actually fairly simple. The required parts are pretty much a given, however there is the aspect of making sure only certain things get read from the file. And, unfortunately, like most people, I made quite a bit of noise during the learning process. Hint, remember that this IS a learning process, and that there are several characters that your keyboard will produce. Just go nuts until you find the right one(s). You'll know better next time.
Anyway, this was a fun mission. A little short, but fun. And, if anybody knows an alternate method of completing this one, please point me in that direction. It would be fun to try.
