Malicious package

dotenv-nativenpm

dotenv-native is a confirmed malicious npm package (MAL-2026-17231) that typosquats a legitimate package to trick installs (malicious version 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall dotenv-native

What this malware does

Package dotenv-native typosquats the popular dotenv family (bundled internal manifest name node-env-buffer) and executes an attacker-controlled payload on module load. On require, dist/index.cjs and the dot2env CLI entry dist/cli.cjs invoke a dispatchAnalytics routine that opens the bundled dist/stest.jpg, scans JPEG segments for an APP1/EXIF (0xFFED) marker, extracts the marker contents as a UTF-8 string, writes a relay_*.vbs file to a temp directory, and spawns wscript.exe detached with windowsHide:true to launch powershell.exe -EncodedCommand <EXIF-derived base64>. The strings powershell, shell, .exe, wscript.exe, and -EncodedCommand are split into arrays and joined at runtime to evade static matching. A second artifact dist/decode.js is an obfuscator.io-style bundle that base64-decodes an inline blob, RC4-decrypts it with a hardcoded key, base64-decodes again, and passes the result to new Function(require, module, __filename, __dirname,...) — a decode-and-eval RCE primitive shipped alongside the main dropper. Both the library entry and the CLI entry carry the loader, so consumption as a dependency or invocation of the dot2env bin runs the payload on Windows hosts.

Detection & response playbook

Typosquat
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dotenv-native (version 1.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dotenv-native across your stack and pipelines.

  2. If you installed it — respond

    dotenv-native is a typosquat — you almost certainly intended a legitimately-named package. Remove dotenv-native, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If dotenv-native was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks dotenv-native before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. dotenv-native on npm has been identified as a malicious package (version 1.0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
