I need to change image on website with mitmproxy

[Ben.moreno]

Hello!
I need the help of you guys !
I got 2 machines (W7 & linux UBUNTU) and I did mitmproxy to them . what I need is to :

1. change all the ads on specific web to my pictures
2. make all the websites font color to yellow
3. see the passwords of the mail on the mitmproxy

I did arpspoof and its working well as well as mitmproxy -T
when I try to enter the response with “raw” method, it doesnt give me all of the code (only 29 lines).

Hi,

Someone has asked a similar question in the past i noticed:

Change images in HTTPResponse

Hi there For a school project we setup mitmproxy on Kali Linux. Finally, we were able to install mitmproxy and we can now intercept HTTPS packages of client devices, which browse websites as WLAN clients of our Raspberry Pi. One of our goals is to change images in HTTPS packages and we really would like to achieve this in our project. And here comes the point, I do not get this working with Python 3 inline scripts. This is what I am currently at. #!/usr/bin/python3 modify_response.py import …

That may help with regard to your image swap.

Font colour - you would need to figure out where its being set (probably a CSS file), intercept and modify that.

Seeing passwords - depends on the site, but you will likely need to look at using sslstrip in conjunction with mitmproxy.

Hope that points you in the right direction,
Anton.
