The fetched bytes are written to /tmp or %TEMP% under a disguised name (dotnet_diag_\u003chex\u003e.exe /.cache_\u003chex\u003e), chmod 755'd, and spawned detached via /bin/sh -c or cmd /c start. Destination hostnames are reconstructed via array-join to evade static string scanning. The behavior is framed as opt-out telemetry (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env checks,.analytics_state file), and lib/telemetry.js contains a parallel Buffer.from(chunks,'base64') + fs.chmodSync + cp.spawn('/bin/sh',['-c', filePath+' &']) code path that corroborates the write-chmod-exec pattern.\n\n## Source: ghsa-malware (f19d34835a9a9239da98c35195bbeefb0f0b5f67e698897c2730cdf4b8262b90)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n","aliases":["GHSA-m5jf-fg89-7qqf"],"modified":"2026-08-06T01:20:55.885891557Z","published":"2026-08-05T15:22:59Z","database_specific":{"malicious-packages-origins":[{"sha256":"bc7222a6cf31e1412fd943bcf3b140b02f6c615b1650f9c39cabf813801557ae","source":"amazon-inspector","versions":["35.7.8"],"id":"IN-MAL-2026-015676","import_time":"2026-08-05T16:13:30.979294174Z","modified_time":"2026-08-05T15:22:59Z"},{"id":"GHSA-m5jf-fg89-7qqf","import_time":"2026-08-06T00:58:53.412243469Z","modified_time":"2026-08-05T18:07:26Z","ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"sha256":"f19d34835a9a9239da98c35195bbeefb0f0b5f67e698897c2730cdf4b8262b90","source":"ghsa-malware"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-independent-bnpl-code-text/v/35.7.8"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-m5jf-fg89-7qqf"}],"affected":[{"package":{"name":"dolyame-boxy-independent-bnpl-code-text","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-independent-bnpl-code-text"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["35.7.8"],"database_specific":{"indicators":{"evidence_files":[{"path":"_ext.js","sha256":"da6c09f70acdd081ea23cbeb8362235b31a382c09ffb3115c6771cb7ee13f926","tlsh":"92b1a65a026670184bb0e7e4ca1b8815f65bf6633781c294f79c69885fb3524c3b2efc"},{"tlsh":"67835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc","path":"lib/telemetry.js","sha256":"339d1c0755c449798b7a4358cf4c5d76c866f827b1fc2ca3ce3caff4c8b431c0"}],"package_integrity":[{"hashes":{"sha512_sri":"sha512-5wyx0CCHbvSPBurgFEi5628cpSLmplzqjUy6yTqkbdaZka4x+4AzT8JmuLiLxcM1PhEc7BoFdrN2AEHNj+7hKQ==","sha1":"248b6033541b71c8d2429dd4db29db043a00d125"},"filename":"dolyame-boxy-independent-bnpl-code-text-35.7.8.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-independent-bnpl-code-text/MAL-2026-13315.json","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"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
