If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

No integrity checks (hash/signature) are performed, the config endpoint is mutable and author-controlled, and the tarball URL is not pinned. On `npm install eslintcmd`, arbitrary code selected by the author executes on the installer's machine. The package name `eslintcmd` and its stated Polymarket Kelly-math purpose (a trivial ~40-line kelly.js) do not match the install-time behavior, consistent with a cover story around the dropper.\n\nAny computer that has this package installed or running should be considered fully compromised.
