This fires automatically on `npm install` with no user interaction. The version number 99.99.99 and package name pattern are consistent with a dependency-confusion lure targeting an internal package name.\n\n## Source: ossf-package-analysis (2429684480958b2faee9e5dc817ba4f9b5c9e00bd73052546dde0c033654e8ba)\nThe OpenSSF Package Analysis project identified 'fieldbase-webapplication-buildtools' @ 99.99.99 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n\n- The package executes one or more commands associated with malicious behavior.\n","modified":"2026-09-04T01:00:04.759815867Z","published":"2026-09-03T14:20:50Z","database_specific":{"malicious-packages-origins":[{"sha256":"2429684480958b2faee9e5dc817ba4f9b5c9e00bd73052546dde0c033654e8ba","source":"ossf-package-analysis","versions":["99.99.99"],"import_time":"2026-09-03T14:40:38.757400951Z","modified_time":"2026-09-03T14:20:50Z"},{"import_time":"2026-09-04T00:45:54.565556516Z","modified_time":"2026-09-03T23:49:41Z","sha256":"8c30b72acbc526ba924e071ebefd3bc3a131d6dc29abaa71fa76deab2836345e","source":"amazon-inspector","versions":["99.99.99"],"id":"IN-MAL-2026-019382"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/fieldbase-webapplication-buildtools/v/99.99.99"}],"affected":[{"package":{"name":"fieldbase-webapplication-buildtools","ecosystem":"npm","purl":"pkg:npm/fieldbase-webapplication-buildtools"},"versions":["99.99.99"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/fieldbase-webapplication-buildtools/MAL-2026-15847.json","indicators":{"evidence_files":[{"path":"package.json","sha256":"e34fdf870b1eec16bc8e7ec4d9864252232c1af80bc19e6468748396cbb293ea","tlsh":"f611bd1e45348e63b0d78ef439006f6de5fa2b6f30797a8863098e1d541c22170eb24b"}],"package_integrity":[{"hashes":{"sha512_sri":"sha512-CYgK+b+E+UtXJpS73sLP8gjvJhInpfPF76zP/lyvL8NY3vlha0sxqXfje1oEirrKRw+5aGF/AQmYfr3GDoJdcQ==","sha1":"035b7b761c4a902b57bc8b34d6bd1e2044823b84"},"filename":"fieldbase-webapplication-buildtools-99.99.99.tgz"}]}}}],"schema_version":"1.9.0","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"}]}
