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.

The Node build at dist/index.js contains a bare `require(\"assertion-utils-js\")` with no assignment — the return value is discarded, so the sole purpose of the statement is to execute that dependency's code when a consumer imports the library. This require is absent from the TypeScript source (src/index.ts) and from the browser build (dist.browser/index.js); it appears only in the Node dist, indicating deliberate injection into the shipped Node artifact. Consumers who require('ethereum-lib-utils') transitively load and execute assertion-utils-js at import time; the actual payload is carried by that unusually-named dependency rather than by this package's own code.\n\nAny computer that has this package installed or running should be considered fully compromised.
