The npm account amel10 published niksinnkatalapp and 9 similar packages within two minutes on 2026-09-30, all with the same setup.js.\n\n---\n_-= Per source details.

The advertised purpose is a trivial celsius-to-fahrenheit conversion, which does not require telemetry or network activity. The package name and 100.0.0 version pin are consistent with a dependency-confusion lure intended to win resolution against an internal package name and beacon out from build environments that install it.\n","affected":[{"package":{"name":"niksinnkatalapp","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["100.0.0"],"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"}],"indicators":{"evidence_files":[{"path":"setup.js","sha256":"d64e24db686969742bde4b94c86541e70d389ca52287cfe1298060d92354d576","tlsh":"1101fef495e0e5b93abc51c8f2a0b84b92b7e028340775d0c8f981547f89af80d728f2"}],"package_integrity":[{"filename":"niksinnkatalapp-100.0.0.tgz","hashes":{"sha1":"cb17274afc8f03ac807aaa0c599b4708a5143690","sha512_sri":"sha512-dLS/AzGVqBOhoTluiQbZQfUdSyyO58wLrCqDapLumHHs8OPUM4tMpkyDAQlUAIuPYCYJgeegG+wmLZH5fNoXRA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/niksinnkatalapp"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/niksinnkatalapp/v/100.0.0"}],"database_specific":{"iocs":{"domains":["s85r5k14qk.execute-api.us-east-1.amazonaws.com"],"files":[{"digests":{"sha256":"13018b47265a09d744aacb91356d8d16b50578a63683930cfced7d17a07a7256"},"note":"preinstall: node setup.js || true","paths":["package.json"],"source":"PACKAGE_ARCHIVE"},{"digests":{"sha256":"d64e24db686969742bde4b94c86541e70d389ca52287cfe1298060d92354d576"},"note":"Executed by the preinstall script.","paths":["setup.js"],"source":"PACKAGE_ARCHIVE"}],"urls":["https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook"]},"malicious-packages-origins":[{"id":"IN-MAL-2026-020940","import_time":"2026-10-04T23:40:44.160156481Z","modified_time":"2026-10-04T23:23:13Z","sha256":"25ce51139798c658f3018f19912e889df1b0ce31025a6236a473d959b12ef0d9","source":"amazon-inspector","versions":["100.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"InvisiRisk, Inc.","contact":["https://www.invisirisk.com","mailto:research@invisirisk.com"],"type":"FINDER"}]}
