solana-dev-toolsnpm
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.
Malicious code in solana-dev-tools (npm)
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for solana-dev-tools (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging solana-dev-tools across your stack and pipelines.
If you installed it — respond
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.
Did it already run?
If solana-dev-tools was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks solana-dev-tools before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
