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 \u0027No dependencies\u0027); 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. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n",
