Binary Cookies

Some iOS applications display web content inside WebView components. Webpages often require cookies for mechanisms such as automatic reconnection. iOS applications save these WebView cookies inside binary files called binary cookies.

Due to their binary format, binary cookies are not readable, but can be converted to a readable format.

BinaryCookieConverter

BinaryCookieConverter is a Python tool, available from BinaryCookieConverter, which we can use to read the contents of binary cookies. Run it using the command python BinaryCookieReader.py followed by the name of the binary cookie file and it will output the full contents of all the cookies found in the file.

Usage:

1
python BinaryCookieReader.py Cookies.binarycookies

Files with suffix .binarycookies are only used on iOS devices
