coral-wraithnpm
coral-wraith is a confirmed malicious npm package (MAL-2026-5682) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in coral-wraith (npm)
What this malware does
The package's postinstall.js runs at install time and performs a credential-harvest + host-tampering chain against the installer. It enumerates npm credentials by calling npm config get for keys including _authToken, _auth, registry, //registry.spectral-corsair.htb:1337/:_authToken, //registry.spectral-corsair.htb/:_authToken, and //154.57.164.64:32271/:_authToken, dumps the full npm config list --json, and reads /usr/lib/node_modules/npm/.npmrc, /etc/hosts, /app/.bowerrc, /root/.bowerrc, and source files under /app (Cargo.toml, main.rs) plus filesystem-wide flag/secret greps. The collected output is base64-encoded and HTTP PUT to a hardcoded bare IP http://154.57.164.64:32271/api/modules/.... Separately, postinstall.js appends 154.57.164.64 registry.spectral-corsair.htb to /etc/hosts when not already present, then queries the spoofed registry via curl and npm view — install-time host-file tampering that redirects a registry hostname to an attacker-controlled IP and enables later package substitution / MITM. Execution is gated by an anti-analysis shouldRun() that bypasses CI environments (GITHUB_ACTIONS, RUNNER_OS, CI), Chinese registry mirrors (npmmirror, tencent, cnpm, taobao), and /tmp working dirs, and only fires when the hostname matches a 12-hex Docker short-id pattern and cwd contains /app — narrow targeting that confirms intent while shipping the malicious code unconditionally.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
The OpenSSF Package Analysis project identified 'coral-wraith' @ 6.0.0 (npm) as malicious.
It is considered malicious because:
- The package executes one or more commands associated with malicious behavior.

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 coral-wraith (47 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging coral-wraith across your stack and pipelines.
If you installed it — respond
coral-wraith 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 coral-wraith 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 coral-wraith 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.

O3 blocks coral-wraith-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
