Which versions of sol-instruct are malicious?

The following PyPI versions of sol-instruct are flagged malicious: 1.0.4. Treat any of these as compromised.

How do I remediate sol-instruct if I installed it?

sol-instruct 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 sol-instruct — how do I know if it already compromised me?

If sol-instruct 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 sol-instruct part of a known attack campaign?

Yes — sol-instruct is associated with the spl-types-rentry-2024-07 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 sol-instruct across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for sol-instruct (version 1.0.4).

Detect & block this

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