The payload uses randomized hex-named identifiers, a signed-integer decode table, and a doubly-unicode-escaped string body to hide its behavior from static inspection. Any consumer that require('eth-react-provider') executes this opaque code in the installer's process. The src/index.js in the tarball contains the clean web3.js source without this payload, indicating the built artifact was tampered. The README/code mismatch (documented React hook API vs. actual web3.js Subscriptions plus loader) is consistent with a trojanized lookalike package rather than a broken release.\n\n## Source: ghsa-malware (b162f07f49b00538ec535c8fb33f0f6561ec39893acb28e55a8450de8a026322)\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","state":0,"publishedAt":"2026-08-19T10:14:36+00:00","modifiedAt":"2026-10-14T22:30:05.2700309+00:00","affected":[{"ecosystem":"npm","name":"eth-react-provider","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/eth-react-provider/v/1.0.0","https://github.com/advisories/GHSA-rr86-r66c-qc54"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-14300","license":"OSV · upstream source license applies","key":"osv:MAL-2026-14300","identifiers":["MAL-2026-14300","GHSA-rr86-r66c-qc54"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
