solana-utilsPyPI
Advisory published Updated
solana-utils is a confirmed malicious PyPI package (MAL-2025-2999) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.1, 0.1.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in solana-utils (PyPI)
What this malware does
The only thing the package does is send out all the given data about a cryptocurrency transaction, including the private key, to a hardcoded webhook.
Feedback from PyPI Team: the package "transaction-utils" may also exploit a known pip behavior to overwrite files of an existing legitime package and replace it with malicious content.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for solana-utils (2 malicious versions).
If you installed it — respond
solana-utils 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-utils 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-utils-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
