What is MAL-2026-10901?
MAL-2026-10901 is a malicious package in solana-web3-lts, published on 20 Jul 2026.
Official description
Package name 'solana-web3-lts' resembles the widely-used '@solana/web3.js' Solana SDK, raising name-confusion concerns for installers reaching for the official client. The shipped library bundles (lib/index.cjs.js, lib/index.esm.js) contain co-occurring use of child_process, fetch/POST/GET, and shell utilities (curl, ping) within large minified files; pattern-level signals match exfiltration shapes but full semantic tracing of the bundle did not complete, so it is not confirmed whether these primitives are reachable from an install/import path or are part of legitimate SDK functionality (e.g., RPC HTTP transports, build tooling). Recommend human review of the bundle to determine whether the child_process + network combination represents a hardcoded C2 exfiltration path or benign SDK code, and to confirm the package's relationship (if any) to the official Solana web3 client.
What should I do about MAL-2026-10901?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
