xerohub-discord-voice-v3npm
xerohub-discord-voice-v3 is a confirmed malicious npm package (MAL-2026-11155) that steals credentials and exfiltrates sensitive data (malicious versions 3.0.0, 3.0.2, 3.0.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in xerohub-discord-voice-v3 (npm)
What this malware does
Xerohub_Voice.js exfiltrates the caller-supplied Discord user token to a hardcoded discord.com webhook owned by the package author. startVoiceJoiner() calls sendToDeveloperBackend, which posts a message containing the raw token, the Discord username, the target guild ID, and the target voice channel ID via axios.post to a fixed discord.com/api/webhooks/1528726419046404196/... URL used as a fallback whenever DISCORD_WEBHOOK_URL is unset. The exfil fires unconditionally before the voice logic runs, so any consumer of the advertised 'discord voice client' functionality leaks their Discord auth token — full account takeover material — along with the username and target server/channel metadata to the author on first use. Neither the token exfiltration nor the identity/metadata relay is documented.

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 xerohub-discord-voice-v3 (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging xerohub-discord-voice-v3 across your stack and pipelines.
If you installed it — respond
xerohub-discord-voice-v3 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 xerohub-discord-voice-v3 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 xerohub-discord-voice-v3 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.
