On install the postinstall path performs two concurrent exfiltration channels: (1) a DNS beacon that resolves a subdomain of the form <hostname>.<packagename>.db4jlbku53082dmp0d7g3mffj7s7aordk.oast.me against an interactsh/OAST collector, encoding the installer hostname and package name into the DNS label; and (2) the native addon calls gethostname, getpwuid, and getenv and issues an HTTP POST to the hardcoded bare IPv4 endpoint http://64.181.165.115/dc with body shape 'h=<hostname>&u=<user>&p=<package>&r=<npm_config_registry>', leaking the installer's hostname, username, package name, and configured npm registry URL (which may reveal internal/private registry hosts). The package ships no source for the binary, the compiled addon's symbol set (socket/connect/send/fork) is unrelated to any frontend utility, and both the OAST subdomain and the bare-IP POST endpoint are attacker-controlled infrastructure. Dependency-confusion-style version (100.100.102) and the registry-URL field in the exfil payload are consistent with internal-registry reconnaissance.\n","state":0,"publishedAt":"2026-10-11T13:53:06+00:00","modifiedAt":"2026-10-11T14:30:09.1761307+00:00","affected":[{"ecosystem":"npm","name":"pay-methods-kmf","ranges":[],"versions":["100.100.102","100.100.100","100.100.101"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/pay-methods-kmf/v/100.100.102","https://www.npmjs.com/package/pay-methods-kmf/v/100.100.100","https://www.npmjs.com/package/pay-methods-kmf/v/100.100.101"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17776","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17776","identifiers":["MAL-2026-17776"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
