Which versions of solana-web3-lts are malicious?

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

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

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

If solana-web3-lts 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-lts part of a known attack campaign?

Yes — solana-web3-lts is associated with the RLMA-2026-05623, IN-MAL-2026-012967, RLUA-2026-06504 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-web3-lts across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for solana-web3-lts (version 1.0.0).

What this malware does

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.
