Which versions of solana-rpc-client are malicious?

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

How do I remediate solana-rpc-client if I installed it?

solana-rpc-client 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-rpc-client — how do I know if it already compromised me?

If solana-rpc-client 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-rpc-client part of a known attack campaign?

Yes — solana-rpc-client is associated with the RLMA-2026-05618, IN-MAL-2026-013034, RLUA-2026-06499 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find solana-rpc-client across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for solana-rpc-client (version 1.0.0).

Advisory published Jul 20, 2026Updated Sep 1, 2026

solana-rpc-client is a confirmed malicious npm package (MAL-2026-10898) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall solana-rpc-client

What this malware does

The package's bundled entry points (lib/index.cjs.js and lib/index.esm.js) co-locate require('child_process'), fetch/POST/GET calls, and references to curl/ping within minified output. The package name suggests a Solana RPC client, which would legitimately make HTTP/RPC calls; keyword co-occurrence in a minified bundle is consistent with both that legitimate shape and an exfiltration shape, and the available evidence does not show the destination URLs, whether any code path runs at install/import time, or whether process.env or credential paths feed any of the network calls. No package.json lifecycle hook content has been confirmed. Routing to human review so a reviewer can de-minify the relevant spans (around lines 5016/5046, 11212/11317) and confirm whether the network destinations are documented Solana RPC endpoints (allow) or attacker-controlled hosts (escalate to block).
