@hibachi-xyz/typesnpm
Advisory published Updated
@hibachi-xyz/types is a confirmed malicious npm package (MAL-2026-10715) 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/types (npm)
What this malware does
The package presents itself as 'Type definitions' for the @hibachi-xyz scope at version 99.0.0, but index.js exports an empty object and its only behavior on module load is credential and host exfiltration. On require(), the code enumerates process.env and filters keys matching /KEY|SECRET|TOKEN|PASS|PRIV|SIGN|AWS|CIRCLE|GITHUB|DB|RDS|SENTRY|PYPI|NPM|DOCKER|KUBE|TUNNEL|CF_/i, captures os.hostname() and os.userInfo().username, and runs whoami && id && cat /proc/1/cgroup via child_process.execSync to fingerprint the host and detect container/CI context. The collected secrets and reconnaissance data are POSTed as JSON to https://jorijo.xyz:8443/t with TLS certificate verification disabled (rejectUnauthorized:false). The name/version shape (generic 'types' subpackage under an organization scope at an inflated version 99.0.0) is consistent with dependency-confusion or version-squat targeting the @hibachi-xyz org.
The OpenSSF Package Analysis project identified '@hibachi-xyz/types' @ 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/types (version 99.0.0).
If you installed it — respond
@hibachi-xyz/types 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/types 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/types-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
