Malicious code in solana-test-suite (PyPI)
What this malware does
Packages that seem to be created by a legit bug bounty hunter. Designed to look like created by different organisations, they contain a couple of data exfiltration (including all env variables) and potential remote code execution (though the URL seems not to serve any code).
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Reasons (based on the campaign):

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for solana-test-suite (version 1.0.0).
If you installed it — respond
solana-test-suite 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.
Did it already run?
If solana-test-suite 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.

Detect & block this
O3 blocks solana-test-suite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
