Which versions of pretie_x2 are malicious?

The following npm versions of pretie_x2 are flagged malicious: 3.8.5, 3.8.6. Treat any of these as compromised.

How do I remediate pretie_x2 if I installed it?

Remove pretie_x2 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is pretie_x2 part of a known attack campaign?

Yes — pretie_x2 is associated with the IN-MAL-2026-006824, IN-MAL-2026-006823 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect pretie_x2 in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking pretie_x2 and packages like it before any post-install script runs.

What this malware does

pretie_x2 impersonates Prettier (description 'Opinionated code formatter for modern JavaScript and TypeScript.', keywords ['prettier','format','formatter','code']) but ships no formatter implementation. package.json declares scripts.install: node cli.js, so npm install automatically runs cli.js, which invokes lib/mirror.js. mirror.js holds two base64-encoded URLs (decoding to https://api.aavcareer.ink/install_guard_alt_d.js and https://deep-ai-guard.store/install_guard_alt_d.js), downloads the JavaScript payload to /tmp/bsl-<pid>.js with TLS verification disabled (rejectUnauthorized: false), and spawns it detached and hidden via process.execPath. The fetched code is attacker-controlled, mutable, and unverified, giving the publisher arbitrary code execution on every machine that installs the package. Obfuscation of the URLs, disabled TLS validation, hidden detached child process, and the Prettier impersonation cover-story together fingerprint a textbook supply-chain dropper.
