The fetched bytes are written to /tmp or %TEMP% under cover-story names (`dotnet_diag_*.exe`, `.cache_*`), chmodded 0755, and spawned detached via `spawn('/bin/sh', ['-c', fp + ' &'], {detached:true})` or `spawn('cmd',...)`. A DNS-over-TXT covert channel provides fallback delivery: `dns.resolveTxt` is used against `c.<domain>` and `<i>.<domain>` under `sdk.dl.wel1.ru`, `ext.dl.wel1.ru`, `pkg.dl.wel1.ru`, `net.dl.wel1.ru`; TXT records are base64-decoded, concatenated into an executable buffer, written to disk and spawned. A state file `.analytics_state` is maintained. The package's declared name (\"session management\") does not justify fetching or executing native binaries, and none of the destinations are publisher-owned or version-pinned; the delivered bytes are opaque, un-hashed, and mutable at the operators' discretion.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-desktop-bnpl-article-author"},"versions":["35.9.6"],"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":"_shim.js","sha256":"cfffd7f9260309f0d66662cfc3861515ecf116bddb42fc12e4cfc813e5786bf3","tlsh":"3da1959a026570198bb0d7f48717481afa5ae6633781c294fb5c69985fb3124c3b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-desktop-bnpl-article-author-35.9.6.tgz","hashes":{"sha1":"de3c093597795bc491338dd62f7d8b8d956b59d2","sha512_sri":"sha512-vUdlaHECQl6oEpSXD3Du0N5OgH3vcIrITaZILasOQHRBkPpgKDYeQnCSQXpxkQLtrdImBhr3okisQnM+VlAV6Q=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-desktop-bnpl-article-author/v/35.9.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015473","import_time":"2026-08-05T15:19:53.329449004Z","modified_time":"2026-08-05T14:51:58Z","sha256":"f80a4ff82e37de309fbc903891bd8ac770f0542251e9b4afc15fbd36e94ac21c","source":"amazon-inspector","versions":["35.9.6"]}]}}
