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\n## Source: ghsa-malware (00760acbc5304cffff15cc81dc411609ad0d815f16f1cc130da08442f8c53221)\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","affected":[{"package":{"name":"eslintcmd","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["0.2.0","0.1.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"scripts/install-check.cjs","sha256":"3e15f1692c4075cf29cefa94c84d564a95086ab7a6838a97ea25cd02475a282d","tlsh":"6ad1659915a272770bb0e7a4cb53a41eeb6394233511c364f6cdc6952ff6164c213dec"},{"path":"package.json","sha256":"2b94dd5d587d1e5cd81bdb05cee6dee045b61b79f42d0ab3008a5fd1baaccbab","tlsh":"2df02237d9504e3668b98e994e792640f4690b5f22b04d1bb0bb604c4fb2163049b72a"}],"package_integrity":[{"filename":"eslintcmd-0.2.0.tgz","hashes":{"sha1":"b08f9687cc140634f9f897d5ca1849fbcb630028","sha512_sri":"sha512-ZR0YnP9VUIXRbN63occfRtbHu7FGyHx3cGwuDAhEVBL7j8zt5oDx2eFmF/voLrOIZ6OK0Inn4qaJbh+DKTrV3A=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/eslintcmd/v/0.2.0"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-73c6-pgjj-9v82"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/eslintcmd/v/0.1.0"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-010623","import_time":"2026-07-15T08:51:04.405304275Z","modified_time":"2026-07-15T07:55:08Z","sha256":"2cf4500fbbfc85f42275772210ace6efb69c5f90d9d0a5edd7c0c75fa271f0c3","source":"amazon-inspector","versions":["0.2.0"]},{"id":"GHSA-73c6-pgjj-9v82","import_time":"2026-07-30T03:51:56.434745Z","modified_time":"2026-07-29T15:00:27Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"00760acbc5304cffff15cc81dc411609ad0d815f16f1cc130da08442f8c53221","source":"ghsa-malware"},{"id":"IN-MAL-2026-013316","import_time":"2026-08-05T07:06:41.004077631Z","modified_time":"2026-08-05T06:05:44Z","sha256":"8b53e77485f429f1e114e9f6b5697ba32f79a0e10497400b138b9431238f1a58","source":"amazon-inspector","versions":["0.1.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
