Greetings Fellow Fiddlers

 

We've used Fiddler successfully for a while to intercept and decrypt https traffic from our iOS application (11.0.2) without any problems. However, it became necessary to move to a new Windows-10 VMWare installation. We also took the opportunity to install Fiddler 5.0.2018.1.14850.

 

We've gone through the various options to "Allow remote computers to connect" and "Decrypt HTTPS". We've also downloaded and run the FiddlerCertMaker. We can see that Fiddler reports that certificates are now generated by "BCCertificateMaker.BCCertificateMaker from CertMaker.dll" and we see the Fiddler "DO_NOT_TRUST_FiddlerRoot" certificate in the Windows-10 Certificate Manager under "Local Computer\Trusted Root Certifications Authorities"

 

Then from the iOS device we've configured the manual proxy and take our Safari browser to the Fiddler Echo Service page where we download the FiddlerRoot Certificate, installed it and finally confirmed that it is marked as "Verified"

 

However, when we run our application or browse to https sites from the iPad, Fiddler acknowledges the access and shows tunnel to various URLs, but there is no https decryption.

 

Furthermore, the Fiddler logs contains the following line repeated for each https access

• SecureClientPipeDirect failed: System.IO.IOException Authentication failed because the remote party has closed the transport stream. for pipe....

Having gone through the process a few times now, there's a fair amount of head scratching going on, What have we missed?

 

All help is very much appreciated.

 

Many Thanks

Hi,

I've just started to work packet capturing and I'm confused about an issue.

When capturing the traffic from a website, I don't see the real target the requests are sent to. what's the reason? is it due to some kind of encoding or what?

Thanks

 

Let me know if further steps I can help troubleshoot on this. Thanks.

Hello

I need help with inserting cookies through FiddlerScript. I have cookies like below which contains " inside cookie value, when I remove " from cookie value I stopped getting response from server. Now the real problem is FiddlerScript doesn't consider any cookie value outside " if I am correct. Pls help in finding some solution for me.

New to Fiddler, Please help. Thanks

Hi there,

I know we don't have a GUI option to filter bodies.

I was thinking about using OnDone for hiding/filtering them.

I just need a way to get the body and a way to block this.

 

 

I'm getting too many packets. I would like Fiddler to exclude packets that have no information valuable for my analysis.

Hello

I want to see only the sessions that set or read cookies, I guess I need a script for that ?!  Any hints are usefull.

Thanks Michael

I recently upgraded to Windows 10, and I love it so far. It appears that Cortana does not function fully for me though. I am running accountability software on my computer called X3Watch. It simply monitors all of this computer's network traffic and filters it through a proxy. Many of my previous Windows 8 (and now Windows 10) apps had to be "enabled" using Fiddler (See my link below for more info). If I click Cortana's search bar, I believe I should see several cards relating to weather, sports, etc. Right? Unfortunately, it's blank for me. All she says is "What's on your mind [name]?" If I watch the traffic in Fiddler, Cortana tries to connect to localhost:58084 via the URL /proactive?form=WNSBOX using the process searchui.exe, but unfortunately it results in an HTTP 502 error. Fiddler does not list it as a Loopback exempt app. Can anyone help? X3watch support was not helpful in solving this.

 

Also if I go into the Cortana Notebook > Settings and disable "Cortana can give you suggestions, ideas, reminders, alerts and more" it appears to show generic cars in the Cortana bar. If I switch it back, I get nothing. If I click on the Cortana "Ask me anything" search bar, it sits there doing nothing until eventually it says "Go ahead and tell me to do something. Interests aren't available at the moment."
