No other file in the package references config's exports, and pino itself contains no such module. The combination of a name/README mismatch (pino cover story on a package named after Hardhat), an unrelated author domain, and a multi-megabyte obfuscated blob that self-executes on import is a masquerade/typosquat delivering a hidden payload to anyone who installs or requires the package.\n","affected":[{"package":{"ecosystem":"npm","name":"hardhat-set"},"versions":["2.21.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"lib/config.js","sha256":"c9b83cdf9b6c915f02485cce0d993653a07cb78d12317904270f808e65529c30","tlsh":"ab1674488181f02393cd5b63bf457aecfc7a68a694cc654b8559bd2de8bc40bd9e2cc4"},{"path":"package.json","sha256":"f10a8bc9cb7f811ac125d88d35cf3ae5ad58b81e7591df108044e019c8a38a42","tlsh":"2a017620deb88e2301ed25424c2a5643ba618c1b6528fc2932dba12c0f9d5fb01bf21d"}],"package_integrity":[{"filename":"hardhat-set-2.21.0.tgz","hashes":{"sha1":"3c68ae78c094294bbdbf78ab87ddb47f7a76ff77","sha512_sri":"sha512-aV2h0irREOmbNOAa3zKRjZK5T5dE6lzAGbDEp2Pm8T1T0+5h7uH7UpTKKe08P6Su/KVLThs4V7iv1Mu1iFnDPA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/hardhat-set/v/2.21.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017077","import_time":"2026-08-07T13:32:44.112846411Z","modified_time":"2026-08-07T12:57:29Z","sha256":"7cf6b9d0ee4a23bfab6e7a3c21f69a36e0655019cf1dd602f93760e233c7f701","source":"amazon-inspector","versions":["2.21.0"]}]}}
