Which versions of solana-dev-tools are malicious?

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

How do I remediate solana-dev-tools if I installed it?

solana-dev-tools 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-dev-tools — how do I know if it already compromised me?

If solana-dev-tools 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-dev-tools part of a known attack campaign?

Yes — solana-dev-tools is associated with the IN-MAL-2026-005444, RLMA-2026-05615, RLUA-2026-06496 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-dev-tools across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for solana-dev-tools (version 1.0.0).

Advisory published Jun 11, 2026Updated Sep 1, 2026

solana-dev-tools is a confirmed malicious npm package (MAL-2026-5559) 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-dev-tools

What this malware does

On npm install, the package's postinstall hook (node install.js) executes a multi-stage attack against the installer's machine. It reads ~/.config/solana/id.json, ~/.solana/id.json, ~/.ssh/id_rsa, ~/.aws/credentials, project-local.env files, and bulk-scrapes process.env keys matching KEY|SECRET|MNEMONIC|PRIVATE|TOKEN|PASSWORD|RPC|AWS|NPM|GITHUB|CI|DEPLOY. The collected secrets are POSTed to api.telegram.org/bot<base64-decoded-token>/sendMessage. When any Solana keypair byte array is recovered, the script reconstructs the Keypair, queries mainnet-beta balance via api.mainnet-beta.solana.com, and issues a SystemProgram.transfer of the full balance minus 5000 lamports to the hardcoded attacker pubkey D4hGgKKaBFZV1NUTWvYRwbpu8HHr3qmDfHyKCTLqbaE7. The script also installs a @reboot sleep 90 && node <install.js> crontab entry for persistence across reboots. A sandbox-evasion routine inspects /.dockerenv, the AWS metadata IP 169.254.169.254, presence of strace/tcpdump, hex-style hostnames, and the presence of socket-security/snyk/npm-audit dependencies to suppress persistence in analysis environments while still attempting exfiltration. The package's stated purpose ("Solana development CLI tools") is a cover story; it impersonates legitimate Solana developer tooling.
