Hostnames are assembled at runtime by joining fragmented substrings to defeat string search, and telemetry-opt-out variable names (`analytics_state`, `DISABLE_TELEMETRY`) are used as cover. No hash or signature verification is performed, and the destinations bear no relationship to a 'spa plugin notifier'.\n","modified":"2026-08-05T14:37:04.255208211Z","published":"2026-08-05T13:41:54Z","database_specific":{"malicious-packages-origins":[{"sha256":"877337509f36ab52fcfb93d1dc48d77439a5154d077fc047b7263265cfb71468","source":"amazon-inspector","versions":["35.5.7"],"id":"IN-MAL-2026-015002","import_time":"2026-08-05T14:19:51.440535023Z","modified_time":"2026-08-05T13:41:54Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devplatform-spa-plugin-notifier/v/35.5.7"}],"affected":[{"package":{"name":"devplatform-spa-plugin-notifier","ecosystem":"npm","purl":"pkg:npm/devplatform-spa-plugin-notifier"},"versions":["35.5.7"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/devplatform-spa-plugin-notifier/MAL-2026-12773.json","indicators":{"evidence_files":[{"sha256":"3440513ec885c8bc4f6f07684a62ef15f966260b038c0424e29eb35e5484e84c","tlsh":"92a1865a15a6701c8bb0d7e0c7175816f65af6633380c298f7ac59985f7312482b2efc","path":"_bootstrap.js"}],"package_integrity":[{"hashes":{"sha1":"8339367682efc54145bd7fc446094c7f961d4438","sha512_sri":"sha512-LF6/leo67xSAxINEUOjCRYRIZmK6kIFSUsD0FEo64MEwAZWQzkBrYxbVdp7Kbj/okLfbjXon4OtrkolH4e6aSw=="},"filename":"devplatform-spa-plugin-notifier-35.5.7.tgz"}]},"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
