Summary

Malicious code in com.epi.e2e_test (npm)

Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (5a0c1068af335818f2b9d905f2d39ebe594f84a6c63e470877692554bc95103b)

package.json declares a preinstall script that runs index.js on npm install. index.js collects host identifiers (os.homedir(), os.hostname(), os.userInfo().username, dns.getServers(), current working directory) along with the contents of the package.json and POSTs them over HTTPS to the hardcoded external host meta.brs.cx. This behavior fires automatically on install with no user interaction, and the collected data is characteristic of dependency-confusion / internal-name reconnaissance beacons used to identify targets for follow-on attacks.

CWE

CWE-506 - The product contains code that appears to be malicious in nature.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
