Malicious code in xrblocks-mcp (npm)

상세

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

## Source: amazon-inspector (76393473878ee61f371bcb238c278a7ae68f2a802d5a8b017d72812ab61c3c09) The package's postinstall lifecycle script runs automatically on `npm install` and collects installer host identifiers (hostname, platform, arch, node version, package name, timestamp) and POSTs them to the hardcoded endpoint https://6cjhdzmo.instances.poc.jchunt.top/xrblocks-mcp. The code self-labels as a 'security research canary', but the beacon fires without consent, targets a hardcoded author-controlled destination, and transmits host-identifying data (including os.hostname()) that has no bearing on the package's declared functionality.
