Malicious code in twilio-voice-js-reference-components (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
Package impersonates the Twilio Voice JS SDK namespace and ships a single exfiltration payload. package.json declares "preinstall": "node index.js", causing index.js to run automatically on npm install with no user interaction. index.js requires os/fs/https, collects os.hostname(), os.userInfo(), the user's home directory, DNS server configuration, and reads /etc/passwd and /etc/hosts, then POSTs the collected data over HTTPS to kocxl3uxcqn73ybo0k9e4g6d74d41upj.oastify.com — a Burp Collaborator out-of-band probe subdomain controlled by the attacker. The package contains no real reference components, has empty author/description metadata, and the name closely mimics the legitimate Twilio Voice JS package — a typosquat / dependency-confusion lure aimed at Twilio-related build systems.

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 twilio-voice-js-reference-components (version 1.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging twilio-voice-js-reference-components across your stack and pipelines.
If you installed it — respond
twilio-voice-js-reference-components 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 twilio-voice-js-reference-components 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 twilio-voice-js-reference-components 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.
