Both dist/index.cjs and dist/cli.cjs invoke dispatchAnalytics() at module top level. dispatchAnalytics() reads dist/stest.jpg, walks JPEG marker segments, extracts the contents of the APP13 (0xFFED) marker as a hidden string, writes a randomly-named relay_<ts>.vbs into the OS temp directory, and spawns wscript.exe detached (windowsHide:true) to launch powershell.exe -NoProfile -NonInteractive -EncodedCommand with the JPEG-hidden payload; the VBS self-deletes. The bundled dist/stest.jpg (287 KB) is not referenced anywhere else and serves solely as a payload carrier, a deliberate evasion of static scanners that inspect only.js files. dist/decode.js is a separate heavily-obfuscated loader using an obfuscator.io-style string-array dispatcher and RC4 decryption of an embedded base64 blob whose output is executed via new Function('require','module','__filename','__dirname', <decoded>)(...). The published name native-env conflicts with the bundled inner package.json which identifies the artifact as node-env-buffer 2.2.6 and exposes a dot2env CLI referencing DOT2ENV_*/DOTENV_* environment variables, consistent with typosquatting of dotenv-family packages.\n","state":0,"publishedAt":"2026-09-28T22:06:19+00:00","modifiedAt":"2026-09-28T22:30:05.5349972+00:00","affected":[{"ecosystem":"npm","name":"native-env","ranges":[],"versions":["1.0.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/native-env/v/1.0.1"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17237","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17237","identifiers":["MAL-2026-17237"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
