solana-web3-v1npm
solana-web3-v1 is a confirmed malicious npm package (MAL-2026-10904) 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-v1 (npm)
What this malware does
Package name closely mirrors the widely-used @solana/web3.js Solana SDK while being published under an unrelated, unscoped name. The bundled lib/index.cjs.js and lib/index.esm.js contain co-occurring patterns of require('child_process'), fetch/POST/GET calls, and shell utilities (curl, ping) within the same minified bundle. Without traced execution, it cannot be confirmed from these matches alone whether the network calls are user-facing RPC client functionality (consistent with a Solana SDK) or a hardcoded exfiltration channel, nor whether the child_process/curl/ping usage is dead/library code or reachable on import. Given the strong name-confusion against a high-traffic SDK target, the combination of HTTP + child_process + shell-tool keywords inside a single bundle, and the lack of clean traced evidence, this should not be auto-allowed; a human should verify the destinations, the reachability of the child_process paths, and whether the package is a legitimate fork/mirror or a confusion-attack lure.

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-v1 (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-v1 across your stack and pipelines.
If you installed it — respond
solana-web3-v1 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-v1 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-v1 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.

O3 blocks solana-web3-v1-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
