solana-web3-stablenpm
solana-web3-stable is a confirmed malicious npm package (MAL-2026-10903) 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-web3-stable (npm)
What this malware does
Package name 'solana-web3-stable' closely resembles the widely-used @solana/web3.js library, raising typosquat concern. The bundled lib/index.cjs.js and lib/index.esm.js contain co-located uses of child_process, hardcoded fetch/POST calls, and shell utilities (curl, ping). These keyword co-occurrences in a minified bundle are consistent with both a legitimate Solana client (which makes RPC POST/GET calls) and a malicious exfiltration shape; semantic verification of the actual call graph was not completed, so intent cannot be confirmed from the captured evidence alone. Routing to human review to confirm whether the network destinations are documented Solana RPC endpoints or attacker-controlled hosts, and whether child_process is invoked at install/import time.

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-web3-stable (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-web3-stable across your stack and pipelines.
If you installed it — respond
solana-web3-stable 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-web3-stable 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-web3-stable 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.
