Which versions of modelconftranslator are malicious?

The following PyPI versions of modelconftranslator are flagged malicious: 8.13.4. Treat any of these as compromised.

How do I remediate modelconftranslator if I installed it?

modelconftranslator is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed modelconftranslator — how do I know if it already compromised me?

If modelconftranslator was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is modelconftranslator part of a known attack campaign?

Yes — modelconftranslator is associated with the 2026-02-urllib-slim campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find modelconftranslator across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for modelconftranslator (version 8.13.4).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall modelconftranslator

What this malware does

During installation, the package starts obfuscated code that downloads and runs remote executables in specific environments - in older packages - attempts to exfiltrate some basic information using DNS requests and then likely cover tracks by installing a similarly named package from private repository

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-02-urllib-slim

Reasons (based on the campaign):

typosquatting
Downloads and executes a remote executable.
obfuscation

Detect & block this

O3 blocks modelconftranslator-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
