## Source: amazon-inspector (95ddc660098b1c73a1899ad3fe471b53ce562ca033669fa64622ff386d774129) package.json defines a postinstall script that invokes `node -e` to issue an HTTPS GET to the attacker-controlled out-of-band callback host db4fe7a2e2lvaraia8k0n4amgw4ir83az.oast.pro, embedding the installer's OS hostname (os.hostname()) and username (os.userInfo().username) in query parameters. The request fires automatically on `npm install` with no caller interaction, confirming code execution on the installer's machine and leaking host-identifying data to a third-party interaction server. ## Source: ossf-package-analysis (90252f22765869df637f77df2754cd36724812550151c9c7c53926bc83daad2e) The OpenSSF Package Analysis project identified 'kmf-vendor-pack' @ 99.0.0 (npm) as malicious. It is considered malicious because: - The package communicates with a domain associated with malicious activity. --- Credit: OpenSSF (source)

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
