HackBrowserData is a command-line tool for decrypting and exporting browser data (passwords, history, cookies, bookmarks, credit cards, download history, localStorage, sessionStorage and extensions) from the browser. It supports the most popular Chromium-based browsers and Firefox on Windows, macOS and Linux, plus Safari on macOS.

It can also decrypt data across machines and operating systems: export the master keys on the origin host, then decrypt a copy of the data offline on any other host — even for a browser that the analyst host's OS cannot run (see Cross-host decryption).

Supported Browsers

On macOS, some Chromium-based browsers require a current user password to decrypt.

Password decryption may fail on macOS 26.4 or later.

¹ Safari requires Full Disk Access; enable it in System Settings → Privacy & Security → Full Disk Access if extraction returns empty results.

² On Windows, decrypting Chromium 127+ cookies (Chrome / Chrome Beta / Edge / Brave / CocCoc) requires the App-Bound Encryption payload built via make build-windows — see Building from source below.

³ These browsers ship only on Windows, but their data is decryptable on any OS: pull the files with archive, export the keys with dumpkeys, then decrypt on macOS or Linux with restore — see Cross-host decryption.

Getting Started

Install

Installation of HackBrowserData is dead-simple, just download the release for your system and run the binary.

In some situations, this security tool will be treated as a virus by Windows Defender or other antivirus software and can not be executed. The code is all open source, you can modify and compile by yourself.

Building from source

Requires Go 1.20+.

git clone https://github.com/moonD4rk/HackBrowserData
cd HackBrowserData
go build ./cmd/hack-browser-data/

Cross-platform build

# For Windows (standard build, no Chromium 127+ ABE cookie support)
GOOS=windows GOARCH=amd64 go build ./cmd/hack-browser-data/

# For Linux
GOOS=linux GOARCH=amd64 go build ./cmd/hack-browser-data/

Windows build with App-Bound Encryption (optional)

Chrome / Chrome Beta / Edge / Brave / CocCoc 127+ protect cookies with App-Bound Encryption. Decrypting those cookies requires a small C payload — Zig (0.13+) is the recommended C toolchain (the Makefile calls zig cc). MinGW-w64 gcc can also build the sources manually if you bypass make payload.

# 1. Install Zig
brew install zig                 # macOS
scoop install zig                # Windows (scoop)
# or download from https://ziglang.org/download/

# 2. Build the payload (outputs internal/abe/payload/abe_extractor_amd64.bin)
make payload

# 3. Build hack-browser-data.exe with the ABE payload embedded
make build-windows

The resulting hack-browser-data.exe includes full ABE cookie decryption on Chromium 127+.
