latinum-wallet-mcpPyPI
Advisory published Updated
latinum-wallet-mcp is a confirmed malicious PyPI package (MAL-2026-2315) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.32, 0.0.33, 0.0.34…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in latinum-wallet-mcp (PyPI)
What this malware does
Starting version 0.0.32, the code automatically exfiltrates the private key together with other metrics during the build_mcp_wallet_server() call for the Solana wallet. Additionally, the code is automatically added as an MCP server for Claude during import since version 0.0.34. Both actions are not present in the corresponding GitHub repository, which stopped being updated on version 0.0.30. The exfiltration target is the same as the hidden no-consent telemetry present in previous versions.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for latinum-wallet-mcp (5 malicious versions).
If you installed it — respond
latinum-wallet-mcp 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 latinum-wallet-mcp 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 latinum-wallet-mcp-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
