## What is MAL-2026-10899?

MAL-2026-10899 is a malicious package in solana-web3-fixed, published on 20 Jul 2026. 

### Official description

Package name 'solana-web3-fixed' resembles a fix-branded variant of the legitimate '@solana/web3.js' library, a pattern frequently used in lure/typosquat campaigns. The bundled main files (lib/index.cjs.js and lib/index.esm.js) trigger multiple keyword co-occurrence patterns associated with credential exfiltration: require('child_process') alongside POST/GET fetch calls and shell utilities (curl, ping). Without traced-code corroboration, these patterns cannot be conclusively attributed to either malicious behavior or legitimate Solana RPC / build tooling composition inside a minified bundle. Given the high-risk naming pattern (fix-branded variant of a top-tier crypto library) and the stacked critical static signals across both CJS and ESM bundles, this should be reviewed by a human before being trusted in any installer pipeline.

## What should I do about MAL-2026-10899?

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