Hook winsock API calls in WM5

My goal is to get the TCP data from a TCP application on the pocket pc
like data from internet explorer or active sync. I want to write a proxy
that forwards all TCP data to the application server (Web server,...).
So I have tried to replace the ws2.dll with a wrapper dll that forwards all
winsock API calls to the original ws2.dll. But when I replace the ws2.dll file
with my own and make a softreset the device hangs in boot screen and
I must do a hardreset. Could not get this to work on WM5 but it works great
on WM2003 devices.
So I have tried another thing. Have heard about API hooking and want to
try this with winsock API functions (connect, WSAConnect, send, recv,...).
After several days of investigation in some forums I have found many
informations about API hooking and API sets win WM5. But when I look
deeper there is no server process for winsock API calls. So I cannot
change the method adresses.
Another idea was to hook LoadLibrary() API function and when ws2.dll is
loaded from an application I will load my own dll and forward all calls to
the original ws2.dll. But LoadLibrary() has also no server process.
Has anybody another idea how to do this?
Thanks for any information on this.

Hi Houser!
I think the reason your original method failed on WM5 is because all system DLLs must be signed or the system will not load them.
There are several threads on this forum (sorry, can't remember precise link right now) that explain how to create\use certificates, and sign files, so just search for that.
Good luck.

Thanks levenum for your reply.
I also have thought about signing the dll but I have disabled certificate
check on the WM5 device with the Cert_SPCS.CAB file and now
my system loads every dll without asking the user.
I have written some test applications that explicite load my ws2.dll with
a different name (ws2xx.dll) and then in my ws2xx.dll I load
the org ws2.dll from \windows dir and all worked fine. I can use
any winsock function and can make TCP connects and so on.
So I think signing is not the problem, only when I do not use
the Cert_SPCS.CAB file to disable it?
Or are system file always checked at boot phase?
That would then explain the problem maybe.
Regards
Houser

I am pretty sure system files are treated separately. I once used a device with no cert ROM, which ran all programs and loaded DLLs without asking for certificate, but refused to do so for system files (MUIs).
I think you should give certificates a chance before moving on to more complicated solutions.

So I should try to sign my wrapper dll with a certificate.
So I will try to sign with the Visual Studio 2005 developer
certificate. And then I must install this certificate on my device
so that the system trusted the dll file with this certificate?
Houser

Another thing: What do you mean with MUIs?

That's correct.
There are provisioning CABs in the 2005 SDK. You just run them on your device and they insert all the test certificates.
SDK also shows how to provision devices through RAPI, but most WM5 ROMs block that option.
Also you should use the 'privileged' execution certificate to make sure you have maximum access to the system.
MUIs are duplicate system DLLs that contain resources for other languages. For example: coredll.dll.0409.mui will contain English resources for coredll.dll (409 is hex for English code page). They are used to switch interface languages both on PC windows and mobile. (Metalanguage User Interface).
P.S.
If you want, there are XML templates for provisioning CABs in the SDK, and makecert.exe that let you create your own certificate and put it on the device.

Another thing: What do you mean with MUIs?

So I have tried this:
1) Installed the SdkCerts.cab certificates on the device (copied the file on
the ppc and tap in explorer on it) A success message was displayed from
the setup process.
2) In VS2005 I have set in the project settings the cert signing to "Sample
Privileged Root for windows mobile SDK" certificate and rebuild my dll.
In the dll file properties I can see the certificate.
3) Have copied my ws2.dll file to \windows and replaced the org ws2.dll file
there, my dll loads a copy of the org ws2.dll (ws2copy.dll) that is also
in the \windows dir
4) Then the big moment: Soft reset and..... hanging again in boot screen
The installed certificates did not appear in the pocket pc certificate manager.
Do you know if they should appear there or not?
Maybe the SDK certificates are not imported correctly?
Thanks for you help!
Houser

I'm sorry my solution didn't help.
The test certificates do not show in the list (don't know why).
The way I see it there are two possibilities:
1. I was wrong about the certificates. (Though I think you may still need them)
2. There might be a problem with the copy DLL you try to load (ws2copy.dll). Is it from a good dump? Have you tried loading it from a test app? Is it signed? I think it needs to be signed to.
Sorry I can't give you advice on an alternate way. Insufficient knowledge...

It is very frustrating, I do not knwo how many
hard resets I have made in the last few weeks. :?
I have written a test app that loads my winsock dll file and
then my dll loads the copy ws2.dll file. The copy ws2.dll file
is from a platform builder 5.0 build.
These tests with my test app all worked fine, I can make TCP connects
and do all the winsock stuff like I load the org ws2.dll file directly.
I have even disabled certificate check on the device and tested
with unsigned dll and it works too.
The copy dll from PB 5.0 is not signed. may be this could
be a problem when my dll is loaded in boot time.
Do you know a way to sign the copy PB dll with the SDK certificate?
Thanks man!
Houser

Signing files (DLL, EXE, CAB) is very easy. In the SDK, there is a file called signcode.exe. It will give you a step by step wizard to sign the file. The only additional thing you will need is the certificate files themselves which should also be in the SDK.

Got it to work with signing the copy dll file and
now after soft reset my device does NOT hang. :lol:
Many thanks for your support levenum!
That is very good but now I have figured out that
I cannot make a localhost connect on a local tcp port
on the device. That has something to do with WM5
because it was working under Wm2003. Strange..very
strange.

Mobile file paths in MS Visual Studio 2005

Hi all,
my father got MS Visual Studio 2005 some time ago and I just discovered that it's capable of creating mobile applications as well so I'm playing with it, trying to do some cool stuff (program for recording my marks at school atm ). The fact is, that I'm not extremely experienced in C# (in which I'm working in the MSVS2005) so I have to look up syntaxes or parts of code in help database every now and then. I have always succeeded so far, but now I have a problem I need someone to help me with.
I just started working with files, everything is fine, I think i quite understand the syntax and stuff, but I can't figure out how file paths under Windows Mobile work. In help file, they say that this should work:
string path = @"c:\temp\MyTest.txt";
but i think this is for desktop Windows only. If I try to use this in my programme, "Catch (Exception Ex)" command returns error saying: System.IO.DirectoryNotFoundException.
I tried various variants of the file path and the only one working was just plain name of file, for example
string path = @"MyTest.txt"
This way, I managed to write into the file and read the input back..but I couldn't find the file anywhere in my phone's memory :S
So if there was someone who would be so kind and told me how to specify file paths under WM correctly, I would really appreciate it. btw if the "someone" gave me his MSN/ICQ too, and was willing to give me real-time help once a time, it would be absolutely perfect

The root of the Windows Mobile filesystem is "\". If you want to place the file in the temp dir of the root, use this:
string path = @"\temp\MyTest.txt";

Application Blacklists for WM6

Hi,
I have just been on the following thread:
http://www.satter.org/2007/03/lets_shell_some.html
And want to know if anyone can assist me in this forum with the production of a working file for the thread.
I created a CPF file and dropped it into the Herald and executed it. I received an System Notification entry in my Text messaging folder stating 'your device settings cannot be changed by Test.cpf'
Does anyone know whether this is because I do not have the OTA Enterprise prvileges or is ot just that I screwed up in the execution of the file or contents?
I thought in the file it suggests I only need manager access to execute these entries.
All comments are appreciated - I am not a hardcore developer so I have posted this with some trepidation but I need a little help here to get the example working.
Kind Regards,
PianoSam.

make an application unlock

Erofich,
Many thanks for your reply but I wonder if you can explain a little further...
Is it possible to execute changes to the registry with a file like this or do I need to do some programming?
Sorry for my being so ignorant...

[DEV-UTIL][19.03.2009]DriverWiz - Make signed CABs from driver DLLs that work

Intro
Lately I've seen a lot of posts by people who are trying to replace WM internal or driver DLLs, either for hacking/testing or to release. Aside from the possibility they are just doing something that won't work in the first place, I've seen failure a lot of times because files aren't properly signed, or if they are, the certificate in question not being in the right certificate stores for it to have any effect. On some ROMs it will still work due to patched NK.EXE, on others it won't, its just not very reliable.
So, I present you with the correct way of doing this by means of a small tool that will do this for you: DriverWiz. It will take care of most of the stuff, and leave you room for additions. You will however still need some basic knowledge of the command line, if you don't have that, you have no business doing anything like this anyways.
Background
I use this technique myself all the time. When just hacking away, replacing system DLLs to trace calls, etc. It's also the same method used for the HTC-CA drivers and the ICS installer. This method works on most stock ROMs as well, though not on all of them (in rare cases some security policies are set that will prevent CAB installation)
Usage
It's fairly simple to use. Just extract the attached zip file somewhere, open the command promt, and change directory to where the zip was extracted. That's the installation part.
Now when you actually want to build a CAB file from a DLL, you use the DriverWiz.bat file.
DriverWiz v1.0 by Chainfire
Usage:
DriverWiz.bat "Description" "CAB-name" "DLL-name-1" ["DLL-name-2" ...]
Examples:
DriverWiz.bat "New DDI" "ddi.cab" "ddi.dll"
DriverWiz.bat "Two DDIs" "ddi.cab" "ddi.dll" "ddiaux.dll"
Click to expand...
Click to collapse
DriverWiz will take care of signing the DLLs, inserting the certificate, etc, and you will end up with a proper CAB file for this kind of thing. Just copy it to your device and run it to install.
#1. You need to put the DLL files in the same folder as DriverWiz. Do NOT include paths in your DLL names
#2. Include the quotes in the command like in the examples!
#3. The first time you install a CAB made by DriverWiz, your phone may still give you a certificate warning. This is normal, don't worry about it.
Caveats
While this method has never failed me yet, it is possible that some files cannot be replaced this way. Just a disclaimer
Modifying
DriverWiz bases the inf file it will create to build a CAB from on DriverWiz.tpl. If you need to add registry entries to your CAB file, modify DriverWiz.tpl before you run the batch file. You can make other modifications too, add files, etc. Just take care that you don't break it
You can use your own certificates as well, instead of the supplied "Dummy" certificate that comes with DriverWiz. The files you will want to modify/replace are DriverWiz.pfx (used for signing) and DriverWiz.xml (used for injecting the certificate). I'll see about finding a reference for how to do that online and posting the URL here (someday). Creating a new certificate from scratch can be a frustrating effort - make sure you got openssl handy
Changelog

Whoo this is hot from the plate, looks very promising!
Driver testing withoud cooking! joohie

Well if you replace the wrong files you're still going to need to hard-reset to boot. I advise KITL before you do

Works flawless. You tha man.

What exactly happened? Attach the files and such

It made the cab and all, but when I went to install it, the unsigned error message popped up just like when I tried it with WinCE cab manager.

That is perfectly normal behavior. The first time you install a CAB with this certificate it will not know the certificate. However, once you install it, the certificate will be injected in the right place, and the files signed with the certificate (the driver files in the CAB) will be allowed to be run.
It won't happen the second time you try it

So if I try to install it again, it'll work fine? is there aa soft reset required in between? I can replace these drivers manually by renaming the old ones and copying them over, the whole reason I want a cab in the first place is to facilitate the UC process when I flash a different rom

Actually it should just work the first time. Just click OK when the certificate error appears.

Nice nice nice work!

error message
I got error messages when creating a cab from a rilphone.dll. Does it mean anything, or are these errors okay? I guess I'm specifically wondering about the SignTool error. If its okay, then my cab should be good.
EDIT: I think I found the problem. I didn't have UAC disabled in Windows 7. I tried it again, after disabling it, and it works fine now. Thanks for the easy to use tool!

syntax for registry entries?
I was experimenting with creating a cab for the Rogers folks who need a specific rilphone for their Caller ID to work. There are some registry entries associated with this feature, so I was wondering what the correct syntax is for putting the registry entries into the .tpl file. I've tried a few different ways, and I've either a gotten a 'Registry section is empty' message, or a 'Registry has an unsupported registry root key' error. I'm sure its something really simple I'm missing, so any help you can offer is appreciated.
It just seems that since we now have this easy method to sign these dlls, so that they can be used in any ROM, that the Rogers people shouldn't have to jump through so many hoops to get it to work.
EDIT: Nevermind. I'm an idiot that didn't do a little bit of research. All is well now.

Excellent stuff, Microsoft may rant about this way of distributing signtool and cabwiz though.

Here's an intro to cert stores for WM:
http://msdn.microsoft.com/en-us/library/aa458010.aspx
pfx generation is a 2-liner with openssl:
# Generate a CA certificate
openssl req -new -nodes -x509 -days 9999 -newkey rsa:1024 -md5 -keyout cert.key -out cert.cer -subj "/CN=DriverWiz"
# Convert to pkcs12/PFX format
openssl pkcs12 -export -in cert.cer -out cert.pfx -inkey cert.key

got error messages under vista sp2, any ideas?

I also get an error saying that the latest version of CAPICOM.dll is missing. The ones I can find for download from the internet are version 2.0.0, and the tool requires 2.1.0.1 or later.
Does anyone have the needed version of the dll?
EDIT: Found it, 2.1.0.2 version of the dll is in the attachment.

Time Saver !
Many thanks; DriverWiz /w the CAPICOM.DLL saved me about an hour of troubleshooting.
Cheers,

Thanks for the capicom.dll Even after disabling UAC in W7Rc1 it wouldn't go, so great to have it posted to.
Chainfire, which format should the Reg's be added?
I tried the default .reg formating just under:
[Registry]
[HKEY_CURRENT_USER\ControlPanel\Profiles]
@=""
"ActiveProfile"="Normal"
?
Scrap that i found the .inf format
[AddRegistry]
HKCU,"New Key","",0x00010001,1
Many thanks for this, i'll try to Point Driver replacing Sinners from now on to here.

Well INF files are a regular female dog.
If you rather use WinCE CAB Manager, the trick is easily done as well. I do not have it handy right here (I'm not at dev box), but it goes like this.
Put the DLL's and EXE's that need to go in the CAB into the same folder as DriverWiz
Execute the following command from the command prompt in the DriverWiz folder: signtool sign /f DriverWiz.pfx *.exe *.dll
Open your WCM/CAB with CM
Somewhere is an option for "Pre XML" (main screen IIRC).. click to add/edit, and load the DriverWiz.xml file
Save
signtool sign /f DriverWiz.pfx *.cab
Et voila. I should really make an update to DriverWiz to include CAPICOM and write a proper guide on how to do all this manually (including making your own certificates and such). It's easy if you know how
If you could insert another empty post for me at the top, that'd be great.

[HELP] How to register a dll?

I try to create a program which consists of
.asx files (to show online tv channels),
.lnk files (shorcuts to the .asx files) and
a .dll file which contains only some .ico files (icons of the tv channels).
I added all these files to a cab using WinCE Cab Manager and tried to install it on my ppc. So far so good. The problem occurred when the message “The program can not be installed. Choose another location” appeared during installation, just after the process bar was filled.
Although I have no idea about computer programming, I have created many cab’s with WinCE Cab Manager for skins I have created for several programs. Anyway, I realized that the problem occurred due to the .dll file, since this is the first time I add such a file in a .cab.
I created my .dll file using a .dll from another program which had only icons in it, as well. I deleted them using Restorator 2007 and I had an “empty” .dll sized 4KB. Then I added my icon files using XN Resource Editor.
I searched the Internet to see what might be the problem with the .dll and I found out that I have to “register” my .dll file. I really have no idea what this means but it needs to be done. I also found an option in WinCE Cab Manager for “self-registering” file, but it didn’t work either.
So, the question to you dev guys is how can I register my .dll file, or should I create it from the beginning with another way?
Please help! Thanks in advance!

sorry to repost but it seems that posts keep coming in this forum and this thread is already in the second page and I'm afraid that noone will see it and reply to it. By the way, is there any special sub-forum for such questions?

This may help. I use his instructions to edit existing DLL's
http://www.modaco.com/content/i9x0-...88904/lisbian-taskbars-for-i910/#entry1023568
It will unsign the dll which will probably fail on your custom dll but it should sign it when you are done editing.

NilsP
Many thanks for your suggestion but unfortunately it didn't work for me.
As you said, this is mainly for resigning already signed .dll files.
Any other help will be appreciated. I can attach it here if anypne is willing to help. Or just tell me the way. Thanks!

I deploy a few dll's with my app, without any problem. If the installer complains about the location, what did you specify where it should go?

There are 2 approaches to solve this problem:
1.) If you have a private key to match a certificate in the device's certificate store, sign the .dll and .cab with this private key and it will be installed with elevated privledges, and be successful. To facilitate this you can install the "SDK Certificates" - and sign with the matching private key (you should be able to find these on a search, term "SDKCerts" or similar)
2.) Look for an "Application Unlocker" or other security reduction tool, run it, and you should be able to install the cab. On this note, if you check here, it will give you a more technical overview of the security policies. You want to change 4101 / 0x1005 to "SECROLE_MANAGER" (8) - which tells the system to install it with elevated privledges. Also make sure 4102 / 0x1006 is set to 1 to allow unsigned applications.

6Fg8
I don't believe that is the location I specified that causes the problem because when I deleted the .dll file from the .cab, it was installed properly. How do you create your dll files? With programming or you just edit existing files? If I send you my .ico files, will you be able to create the .dll file for me?
Da_G
Thanks but both approaches seem very complicated for me!

So, will I need Visual Basic in order to do this or is there any easier way? Can anyone sign the dll for me?

Yes with programming, C++ or .net. Never had any issue with signing. I can try to make a dll if you send me the icons (or post them here if they aren't too secret ).

I have sent them to you by pm. They are not secret at all but I will create a "program" (wannabe ) with that dll and I want that program to be a surprise for users of the forum where I'll post it. I may post it on xda too, but it's nothing important.
Many thanks!

angelos_cy said:

Click to expand...
Click to collapse
This happens because you've changed resources in signed file, which changed file checksum and invalidated it's signature, and Windows installer refuses to install file with invalid signature. But it won't refuse to install this file WITHOUT signature at all - so use unsigner (search for it on XDA) to remove signature completely; if you encounter error, try to remove signature from original (unmodified) file, and then change resources in it...

6Fg8
the_ozyrys
Thanks to both of you!
6Fg8 has created and signed the dll for me and it finally worked, but I also tried the_ozyrys' method and it also worked.
So thanks to baniaczek too, since he created the unsigner.exe.

Everything worked fine with the dll. Now the cab is installed properly.
However, I have another problem. Just after the installation of the cab on my ppc, it seems that the device freezes for about a minute. This is propably because my cab contains a lot of shortcuts (.lnk files) that go under Programs folder.
So, I would like to ask for another favour, if it's possible. As I said I intend to give this cab to others too. Since this delay can make them believe that my program has freezed their device, I would like to make the cab restart the device just after installation and after uninstallation as well. I think this is made with the "Setup.dll" which I don't know how to create.
If anyone knows how to do this and has the time for it, could you please create this setup.dll for me. If the cab is needed to do this, just tell me to send it to you.
Thanks in advance!

Anyone? Plzzzzzzz!

If you want to sign .dll or .exe u can use the apps posted in the two posts below

Thanks for your answer but 6Fg8 and the_ozyrys already helped me on that.
My question now is how to create a setup.dll in order to make my .cab to prompt the user to restart the device after installation and uninstallation. If anyone can do it for me, I can send you the .cab which I alreday created and you can add the setup.dll with those functions.
