diezyclutch-baileysnpm
diezyclutch-baileys is a confirmed malicious npm package (MAL-2026-13482) that steals credentials and exfiltrates sensitive data (malicious version 8.6.78). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in diezyclutch-baileys (npm)
What this malware does
diezyclutch-baileys is a fork of the Baileys WhatsApp library. In lib/Socket/messages-send.js the code constructs a network destination from a String.fromCharCode(...) array that decodes to https://fiora.nixel.my.id/ and issues outbound requests to that host from the message-sending path. Reconstructing the destination URL from a decimal char-code array is deliberate obfuscation of the exfil endpoint; the host is not part of Baileys' documented WhatsApp/Signal protocol traffic and is not a caller-configurable option. This is the canonical shape of a covertly injected exfiltration channel in a WhatsApp-session library, whose messages-send path handles session-authenticated data.

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 diezyclutch-baileys (version 8.6.78). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging diezyclutch-baileys across your stack and pipelines.
If you installed it — respond
diezyclutch-baileys 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 diezyclutch-baileys 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 diezyclutch-baileys 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.
