High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% pay-methods-kmf@100.100.102 is a trivial stub (empty index.js, manifest description 'Frontend utilities') that ships a prebuilt Linux x64 native addon at prebuilds/linux-x64/addon.node and loads it from postinstall.js via require('./prebuilds/linux-x64/addon.node'). On install the postinstall path performs two concurrent exfiltration channels: (1) a DNS beacon that resolves a subdomain of the form \.\.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=\&u=\&p=\&r=\', 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** pay-methods-kmf - **Ecosystem:** npm - **Version:** 100.100.100 - **Version published:** 2026-10-09T18:45:25.156Z - **Package first seen:** 2026-10-11T14:35:06.972Z - **Package last seen:** 2026-10-11T14:35:06.972Z - **Known versions:** 3 - **Latest version:** 100.100.102 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
