Which versions of @uisp/utils are malicious?

The following npm versions of @uisp/utils are flagged malicious: 99.0.0, 99.0.1, 99.0.2. Treat any of these as compromised.

How do I remediate @uisp/utils if I installed it?

@uisp/utils 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.

I already installed @uisp/utils — how do I know if it already compromised me?

If @uisp/utils 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.

Is @uisp/utils part of a known attack campaign?

Yes — @uisp/utils is associated with the IN-MAL-2026-007706, IN-MAL-2026-007704, IN-MAL-2026-007705, GHSA-8gmj-7w3h-39fx campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @uisp/utils across my projects, lockfiles, and CI pipelines?

Malicious package

Advisory published Jun 29, 2026Updated Aug 13, 2026

@uisp/utils is a confirmed malicious npm package (MAL-2026-6565) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.1, 99.0.2). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall @uisp/utils

What this malware does

Package published to the public npm registry under the @uisp scope at version 99.0.1 — the canonical dependency-confusion shape (organization-matching scope plus inflated version to outrank private internal releases). package.json declares scripts.preinstall="node beacon.js". beacon.js unconditionally runs child_process.execSync('whoami') and exfiltrates the base64-encoded output to a hardcoded Burp Collaborator host (w963dgom49n3ibi6677fuaxd64cv0loa.oastify.com) via both a DNS lookup of NONCE.<b64>.<collab> and an https.get to https://<collab>/<nonce>/whoami/<b64>. Installer harm: running npm install against the public registry (or any misconfigured registry resolution that falls through to it) auto-executes attacker code on the build host and leaks host identity to an external out-of-band collector. The README's claim of authorized research does not constitute consent for arbitrary installers and does not mitigate the install-time RCE + exfiltration mechanism.

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.
