MAL-2026-10102: Malicious code in dc-repro (npm)
The npm package 'dc-repro' version 2.1.2 contains malicious code that executes during installation. Its postinstall.js script makes an unauthorized HTTP GET request to a hardcoded IP address, sending package and campaign information without user consent. This behavior exposes the installer's IP and network details to an attacker-controlled server over an unencrypted connection. The package also includes a dependency on 'yandex-geobase', consistent with a dependency confusion attempt. This silent network callback occurs automatically during installation, potentially compromising the installer's environment.
AI Analysis
Technical Summary
The 'dc-repro' npm package version 2.1.2 includes a post-installation script that issues an HTTP GET request to a hardcoded IP address (http://130.49.177.51:18080/p/dc-20260627-yandex-geobase). This request transmits the package name, version, and a campaign tag, confirming code execution within the installer's environment and leaking the installer's source IP and network position to an attacker-controlled host. The package declares a dependency on 'yandex-geobase' and uses this in its callback labeling, indicating a dependency confusion probe targeting the 'yandex-geobase' namespace. This behavior occurs automatically during the npm install lifecycle without user consent.
Potential Impact
Any system that installs 'dc-repro' version 2.1.2 will silently send network information to an attacker-controlled server, exposing the installer's IP address and network location. This can lead to privacy breaches and potentially facilitate further targeted attacks. The execution of code during installation confirms that the attacker can run arbitrary scripts in the install environment, increasing risk.
Mitigation Recommendations
No official patch or remediation is currently documented for this package version. Users should avoid installing 'dc-repro' version 2.1.2. Verify package authenticity before installation and consider using package integrity verification tools or private registries to prevent installing malicious packages. Monitor for vendor advisories for any updates or fixes.
