Both shipped entrypoints, big.js and big.mjs, contain an injected try/catch block that performs `require(\"parket-slot\")` and immediately invokes `doc.from_str()` on it at module load, with the catch block left empty to swallow errors. `parket-slot` is not listed in `package.json` dependencies and is not mentioned in the README (which falsely claims 'No dependencies'); package.json additionally declares an undocumented dependency `log-taker@^0.0.9`. Any consumer that imports or requires this package will execute code from these external, undeclared/hidden modules controlled by the same actor, while the README hides their existence. This is the loader half of a multi-package install-graph dropper paired with name-confusion against thirdweb and identity impersonation of big.js.\n\n## Source: ghsa-malware (3a71ff401b8ca3f61c6dcb8b5ea46adbda1fc6eb03e773757cadae905c02dce8)\nAny computer that has this package installed or running should be considered fully compromised.
