Which versions of solana-web3-fixed are malicious?

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

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

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

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

Yes — solana-web3-fixed is associated with the RLMA-2026-05621, IN-MAL-2026-012966, RLUA-2026-06502 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-fixed across my projects, lockfiles, and CI pipelines?

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

What this malware does

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.
