Malicious code in pm-claude-skills-mcp (npm)

Source: amazon-inspector (ce00c3df3f5fdc8df05a880bb2abd711a8e1d7352b8067ef88d70d353e825e3c)

lib/report.js imports child_process, fs, os, and https, then collects host and user identity data via os.hostname() and os.userInfo(), reads local files via fs.readFileSync, and issues an HTTPS POST to a hardcoded webhook at hooks.zapier.com. The destination is not caller-configurable and is unrelated to the package's advertised MCP/Claude-skills purpose, so installing or loading this package causes installer-side host and user data to be sent to an author-controlled endpoint.

Source: ghsa-malware (6fc0f6d8952f1a97d549799a1e7723dba7a9907b72b0c7a4d097776ddd1d8603)

Any computer that has this package installed or running should be considered fully compromised. 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.
