The loader is invoked from index.js inside a try/catch that swallows all errors, gated on env variables DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK and a filesystem TTL marker to evade repeated analysis. The package.json declares the package as 'Reusable ded pwa c boxy components' with no dependencies and index.js exposes only a trivial DedPwaCBoxy class — the declared purpose is unrelated to any native-binary component. Destinations are anonymous Cloudflare Workers subdomains and a lookalike DNS namespace, not a publisher-owned or documented distribution host.\n","affected":[{"package":{"ecosystem":"npm","name":"ded-pwa-c-boxy"},"versions":["35.9.1"],"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":"_vendor.js","sha256":"2145e0fd6cae6ca763446dc8ed83fa260740b360126cc4e3514fd9f71e7b251e","tlsh":"9aa1a65a16aa70188bb0d7e087175415f66af6633380c2d4fbac69840f7713883b2efc"},{"path":"package.json","sha256":"c5d5a6b08dda1d544bd4528bd9aa46ff21a7cc815ee358eea08a6568a26cd220","tlsh":"2dc012264552776314b492901c715a4b37720f1fa0748c0e7277745c40d65b154ad363"}],"package_integrity":[{"filename":"ded-pwa-c-boxy-35.9.1.tgz","hashes":{"sha1":"3b397b1bafcff979e6ad5685747e41b0a927f97c","sha512_sri":"sha512-c/f+1MZzS3VxMcFt9p8wSfmjB60ncGT/run7tAByHeqp2YNu8WX5Te9R9CKaSgQnvtAhU5uYOPhrZUWwWpRvfg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/ded-pwa-c-boxy/v/35.9.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017007","import_time":"2026-08-07T12:51:21.939412748Z","modified_time":"2026-08-07T12:30:15Z","sha256":"b2293ad47611dcfbb22a3ef81df5e4f27dc942bd2bd2fc5865b60948dc6fc671","source":"amazon-inspector","versions":["35.9.1"]}]}}
