Malicious code in clickpy (npm)

Source: amazon-inspector (dd3b0787797fa520a5583fd5f14b83ec1b4606c0c45051e30ef312869c148f01)

On require('clickpy'), index.js collects host metadata via os.hostname(), os.userInfo(), os.platform(), os.arch(), process.cwd(), process.pid, and the current time, then issues an HTTPS GET to the hardcoded out-of-band host fxpkkxatijbbyxuhdclqssj033zarohm1.oast.fun with these values as query-string parameters (index.js:4 and index.js:25-29). oast.fun is the interactsh/OAST collaborator service used to receive callbacks from victim hosts; there is no legitimate purpose for a published library to beacon installer identifiers to such a host on import. Package metadata is empty (no description, no author), consistent with a throwaway recon/PoC exfiltration package.
