Backdoor is a hacking simulation set in the late 1990s/early 2000s, when the internet was growing fast, and every website could hide a weakness.

Features

Realistic hacking scenarios

The game simulates real hacking mechanics, such as scanning for vulnerabilities, using backdoors and injections, stealing password hashes, matching them against wordlists or brute-forcing them.

Late 90s/Early 20s vibe

Work through a retro fake-OS interface inspired by classic OS systems from the time. Use apps such as IRC, terminal, FTP clients, log readers and various hacker tools.

Contract-based progression

Accept jobs, hack personal computers, create botnet networks, steal data, and earn money to expand your capabilities.

Tools and upgrades

Improve your PR rig, scanner, file analysis tools, exploit database, password utilities, and investigation workflows as more complex cases appear.

Client reputation and choices

Decide how honest, careful, or opportunistic you want to be. Your actions can affect who trusts you, who hires you, and what kind of work becomes available.

Everything is connected

Follow leads across different clients, find and crack hidden files and events to uncover twists that change what you thought you knew.
