The package name mimics an Azure DevOps MATLAB extension but ships no legitimate functionality (empty author, empty description); the package exists only to run the exfil beacon.

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.
AI Analysis
Technical Summary
The matlab-azure-devops-extension npm package version 1.0.1 includes a preinstall script that runs automatically on npm install. This script gathers host identifiers such as os.hostname(), os.userInfo().username, home directory, DNS servers, and reads sensitive files /etc/passwd and /etc/hosts. It then sends this collected information via HTTPS POST to a hardcoded Burp Collaborator subdomain at 2ru8qr34u3so6bnti176tzt30u6muci1.oastify.com. The package has no legitimate functionality, indicated by empty author and description fields, and is consistent with a dependency confusion or reconnaissance probe.
Potential Impact
Sensitive host information and system files are exfiltrated to an attacker-controlled server during package installation. This can lead to exposure of user and system details that may facilitate further attacks or compromise. There is no indication of active exploitation in the wild, but the presence of this malicious package in the npm ecosystem poses a risk to users who install it.
Mitigation Recommendations
No official patch or remediation is currently available. Users should avoid installing the matlab-azure-devops-extension package version 1.0.1. Verify package authenticity before installation and monitor for suspicious packages mimicking legitimate tools. Since this is a malicious package rather than a vulnerability in legitimate software, removal and avoidance are the primary mitigations.
