BLACKSITE OS — the nightjar pentest bench as a web operating system
BLACKSITE OS by NIGHTWARE LABZ is a windowed operating system that runs entirely in a browser tab: a real shell over a persistent virtual filesystem, 636 commands, eight programming engines (Python, JavaScript, Lua, SQLite, Scheme, Brainfuck, WebAssembly, CHIP-8), git and SSH clients built in, relaychat (a built-in IRC client whose house channel is #nosuchmachine on OFTC), and the Daylight Bottle age-encrypted message desk. Doctrine: one knock, read, grade. Public targets only.
The companion BLACKSITE WEB bench suite runs DNS lookups, TLS inspection, HTTP security grading, TCP connect checks, domain recon, email security grading, JWT and certificate inspection, hashing, codecs, and subnet math directly in the browser. Read the Orange Book — a programming book about building a cryptographic language — and browse NIGHTWARE LABZ projects including nightjar, the native iOS and macOS network instrument this site ports.
