Which versions of solana-web3-patched are malicious?

The following npm versions of solana-web3-patched are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate solana-web3-patched if I installed it?

solana-web3-patched 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.

I already installed solana-web3-patched — how do I know if it already compromised me?

If solana-web3-patched 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.

Is solana-web3-patched part of a known attack campaign?

Yes — solana-web3-patched is associated with the RLMA-2026-05624, IN-MAL-2026-012969, RLUA-2026-06505 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

What this malware does

Package name 'solana-web3-patched' resembles the legitimate '@solana/web3.js' library and is published as an unscoped lookalike at version 1.0.0. The bundled lib/index.cjs.js and lib/index.esm.js contain co-occurring patterns of child_process import, fetch/POST/GET calls, and shell utilities (curl, ping) within the same files. Pattern matches alone in a minified/bundled file cannot conclusively distinguish legitimate Solana RPC client behavior from exfiltration, and traced-code corroboration is unavailable. Given the typosquat-shaped name plus presence of child_process + outbound HTTP + curl/ping primitives in the bundle, the package warrants human review before allowing into installer environments. A reviewer should verify whether the child_process and curl/ping references are reachable at require/install time and whether any hardcoded destinations are attacker-controlled.
