## What is MAL-2026-10900?

MAL-2026-10900 is a malicious package in solana-web3-fork, published on 20 Jul 2026. 

### Official description

Package name appears to fork or imitate the well-known @solana/web3.js library. Bundled files lib/index.cjs.js and lib/index.esm.js contain co-occurring patterns of child_process usage, fetch/POST/GET calls, and shell utilities (curl, ping) within the same minified bundles. These keyword co-occurrences in a minified Solana SDK fork are concerning but cannot be conclusively distinguished from legitimate SDK behavior (RPC calls, build tooling) without semantic verification of the bundle. Specific hardcoded attacker C2 endpoints, credential-theft paths, or install-time lifecycle hooks have not been confirmed. Given the name-collision with a major crypto SDK and the suspicious pattern stacking in the bundle, manual review is warranted before allowing installer use.

## What should I do about MAL-2026-10900?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
