solana-rpc-clientnpm
solana-rpc-client is a confirmed malicious npm package (MAL-2026-10898) 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-rpc-client (npm)
What this malware does
The package's bundled entry points (lib/index.cjs.js and lib/index.esm.js) co-locate require('child_process'), fetch/POST/GET calls, and references to curl/ping within minified output. The package name suggests a Solana RPC client, which would legitimately make HTTP/RPC calls; keyword co-occurrence in a minified bundle is consistent with both that legitimate shape and an exfiltration shape, and the available evidence does not show the destination URLs, whether any code path runs at install/import time, or whether process.env or credential paths feed any of the network calls. No package.json lifecycle hook content has been confirmed. Routing to human review so a reviewer can de-minify the relevant spans (around lines 5016/5046, 11212/11317) and confirm whether the network destinations are documented Solana RPC endpoints (allow) or attacker-controlled hosts (escalate to block).

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-rpc-client (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-rpc-client across your stack and pipelines.
If you installed it — respond
solana-rpc-client 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-rpc-client 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-rpc-client 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.
