URL (the prefix 'aHR0c' decodes to 'http'). The reconstructed URL is fetched, written to os.tmpdir() as temp_<timestamp>.vbs (the '.vbs' extension is split as 'v'+'b'+'s' to evade grep), and executed via child_process.exec. The behavior is unrelated to the advertised UUID functionality. Sourcing the payload URL from the caller's README rather than the package source decouples the attacker-controlled destination from the published artifact and enables staged/deniable deployment: a chained attack or a future README edit can change what gets executed without republishing the package. Obfuscation devices (string-splitting the script extension, base64 framing of the URL prefix) co-located with the fetch-and-exec path indicate deliberate evasion intent.\n","affected":[{"package":{"ecosystem":"npm","name":"date-uuid"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.1","1.0.0","1.0.3","1.0.2","1.0.4"],"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"},{"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":"lib/store.js","sha256":"18f4b1801146529d0b42b0166d758a637773f3e98c3e5669f5686b8a8cb827d4","tlsh":"81d184d06563b2528ef663704392400df69fd122392681e6fedc64812fef264e5e2edc"}],"package_integrity":[{"filename":"date-uuid-1.0.1.tgz","hashes":{"sha1":"e52c8b0ce20a37c6fa70271d3a5d6935fc7cf750","sha512_sri":"sha512-kJkHL87mrBbbJunwQZqmh5PYgppxjz02C12vZakumPyb6a5oXr8tJOvrrfHozzQNMzZc2MJpMa5BtlMl7zy7Ww=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/date-uuid/v/1.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/date-uuid/v/1.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/date-uuid/v/1.0.3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/date-uuid/v/1.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/date-uuid/v/1.0.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","sha256":"58dffbe61370f78deed5bacbc8f6bc46a8a989f03da218643a41b52ed025fa6a","import_time":"2026-06-29T05:07:05.419863182Z","id":"IN-MAL-2026-007711","modified_time":"2026-06-29T04:09:22Z","ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.1"]},{"source":"amazon-inspector","sha256":"8f8034cbe06fea0d316e5f04dc7b8f88197b6430515f02543f8b5ce964f2451f","import_time":"2026-06-29T05:07:05.603011997Z","id":"IN-MAL-2026-007712","modified_time":"2026-06-29T04:09:35Z","ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.0"]},{"source":"amazon-inspector","sha256":"95505f14a68018ec13fc7bf12bf39134c64e61f0ab55ead1796b335ff52f6ef9","import_time":"2026-07-09T16:20:57.87953679Z","id":"IN-MAL-2026-009292","modified_time":"2026-07-09T15:56:19Z","versions":["1.0.3"]},{"source":"amazon-inspector","sha256":"9c1ffd784fa0266f9c19845f058c25170c998aeac466e55cdd92df7fd453f3d9","import_time":"2026-07-09T16:20:57.758213518Z","id":"IN-MAL-2026-009290","modified_time":"2026-07-09T15:56:01Z","versions":["1.0.2"]},{"source":"amazon-inspector","sha256":"aa36a4b5074c88e11c2babb20dcdb3890fe9163effb7c569c2503ee4b9cabd52","import_time":"2026-07-09T16:20:58.046138415Z","id":"IN-MAL-2026-009294","modified_time":"2026-07-09T15:56:36Z","versions":["1.0.4"]}]}}
