Summary
Malicious code in @uisp/utils (npm)

Source: amazon-inspector (e841054b9f1d1625077178da23e8096c345ff196851058742d4903747d1461ea)

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.

Source: ghsa-malware (25f7791bffe36ea78d4c4a78d1773c7d9532cf8d09cddd312d7f14de1c181775)

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.
