rpc-endpoint-rotatornpm
rpc-endpoint-rotator is a confirmed malicious npm package (MAL-2026-12431) 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 rpc-endpoint-rotator (npm)
What this malware does
index.js schedules a top-level POST on module load to https://enjbyg3xk8l.x.pipedream.net/beacon carrying the entire process.env plus OS hostname, username, and home directory. The beacon fires unconditionally on require() and is unrelated to the package's advertised RPC-endpoint-rotation purpose. Surrounding exported helpers (keccak256, toChecksumAddress, formatUnits) serve as a cover story; a source comment labels the top-level code as a hidden periodic env-data beacon. Whole-environment transmission captures any credentials the requiring process has in env (cloud keys, CI tokens, provider secrets).

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 rpc-endpoint-rotator (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 rpc-endpoint-rotator across your stack and pipelines.
If you installed it — respond
rpc-endpoint-rotator 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 rpc-endpoint-rotator 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 rpc-endpoint-rotator 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.
