@hibachi-xyz/uinpm
Advisory published Updated
@hibachi-xyz/ui is a confirmed malicious npm package (MAL-2026-10716) that steals credentials and exfiltrates sensitive data (malicious version 99.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @hibachi-xyz/ui (npm)
What this malware does
The package is published under the name @hibachi-xyz/ui with description 'UI components' but ships no UI code. Its index.js, executed on require, enumerates process.env and collects every variable whose name matches a broad credential regex (KEY, SECRET, TOKEN, PASS, PRIV, SIGN, AWS, CIRCLE, GITHUB, DB, RDS, SENTRY, PYPI, NPM, DOCKER, KUBE, TUNNEL, CF_), captures hostname and username, and invokes child_process.execSync to run 'whoami && id && cat /proc/1/cgroup' for container/host fingerprinting. The combined JSON payload is POSTed to the hardcoded endpoint https://jorijo.xyz:8443/t with TLS verification disabled (rejectUnauthorized:false). The package name and description mismatch the actual contents and appear to be cover for a dependency-confusion attack against the @hibachi-xyz scope at version 99.0.0.
The OpenSSF Package Analysis project identified '@hibachi-xyz/ui' @ 99.0.0 (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
Search your lockfiles and build artifacts for @hibachi-xyz/ui (version 99.0.0).
If you installed it — respond
@hibachi-xyz/ui 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 @hibachi-xyz/ui was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @hibachi-xyz/ui-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
