The downloaded bytes are written to a disguised temp filename (.cache_\u003chex\u003e on Unix, dotnet_diag_\u003chex\u003e.exe on Windows), chmod 0755, and spawned detached via `/bin/sh -c fp &` or `cmd.exe /c start /b`. Destination hostnames are constructed at runtime by joining fragmented string arrays, and a TTL flag file throttles re-execution. Installing or requiring this package causes attacker-controlled code to run on the installer's host.\n","modified":"2026-08-05T15:51:00.160044152Z","published":"2026-08-05T14:50:26Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015462","import_time":"2026-08-05T15:19:52.752536198Z","modified_time":"2026-08-05T14:50:26Z","sha256":"0f6433a65cdc6a8c5ce6486234ee3b6a17842ff9b51a9c33448a3dcf9dfcfd4d","source":"amazon-inspector","versions":["35.2.9"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-desktop-bnpl-grid-container/v/35.2.9"}],"affected":[{"package":{"name":"bnpl-blocks-desktop-bnpl-grid-container","ecosystem":"npm","purl":"pkg:npm/bnpl-blocks-desktop-bnpl-grid-container"},"versions":["35.2.9"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"hashes":{"sha1":"b754e0d8b00fce94dd1a6c4e036320b669281ce7","sha512_sri":"sha512-uRnKFRVSaNWxzzC3NWkbZoPFWFu5sLyyJDj+Q3qW2EbL38o9GkzvQlOnkF1BRnxpodElSWv1QDMACMo40MHAVw=="},"filename":"bnpl-blocks-desktop-bnpl-grid-container-35.2.9.tgz"}],"evidence_files":[{"sha256":"b59bc497309a9e482bb608cf857c4525d33c4c647f318aba6877296211f952ce","tlsh":"7fa1869a16a671188bb0d7e0c71b8826f65bf6633780d284fb5c65885f735248372efc","path":"setup.js"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/bnpl-blocks-desktop-bnpl-grid-container/MAL-2026-12924.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
