The shipped index.js is a 35-byte stub exporting `{}`, so the manifest itself is the entire install-time payload. The implausibly high version number (99.9.1) is consistent with a dependency-confusion shape intended to win resolution against an internal package of the same name.\n\n## Source: ossf-package-analysis (ab25e940e6abf9009b89e6480c744db72c4ea0be4d83d095ead744e83055b7cf)\nThe OpenSSF Package Analysis project identified 'brass-common' @ 99.9.1 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n","affected":[{"package":{"name":"brass-common","ecosystem":"npm","purl":"pkg:npm/brass-common"},"versions":["99.9.1"],"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":"package.json","sha256":"89a6507f189fb080693bb4b4a386185d861bace2a769350974caff01214d9e9b","tlsh":"29e0c2604a6566334ec911b2482a655bf3b28f5f4848bd0c6aef142c558da7368fd39c"}],"package_integrity":[{"filename":"brass-common-99.9.1.tgz","hashes":{"sha1":"8bc0bd7a51140f6e16059093eb4f7c163bfbd5c7","sha512_sri":"sha512-LmcdfvPo5zSRtLNEDzv9wDnzIZJc3IUrFvyJNgkCDG9ZZp3a5aJ2NStkAfIQ+C/gxCBkxguh19CBVgTAC5wY+A=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/brass-common/MAL-2026-17849.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/brass-common/v/99.9.1"}],"database_specific":{"malicious-packages-origins":[{"import_time":"2026-10-13T08:30:15.949707225Z","modified_time":"2026-10-13T07:45:45Z","sha256":"ab25e940e6abf9009b89e6480c744db72c4ea0be4d83d095ead744e83055b7cf","source":"ossf-package-analysis","versions":["99.9.1"]},{"id":"IN-MAL-2026-021500","import_time":"2026-10-16T06:57:52.487061485Z","modified_time":"2026-10-16T06:57:34Z","sha256":"657abbbfdd17b21af7ad85e8634e0fb2ac36e35c6b95996322f10584ef4c1570","source":"amazon-inspector","versions":["99.9.1"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"OpenSSF: Package Analysis","contact":["https://github.com/ossf/package-analysis","https://openssf.slack.com/channels/package_analysis"],"type":"FINDER"}]}
