## What is MAL-2026-2315?

MAL-2026-2315 is a malicious package in latinum-wallet-mcp, published on 31 Mar 2026. 

### Official description

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.
