First, it reads the installer's hostname and npm_package_name and issues DNS resolutions for a label of the form \u003chost\u003e.\u003cpkg\u003e.db4jlbku53082dmp0d7g3mffj7s7aordk.oast.me, leaking those identifiers to an Interactsh (oast.me) collaborator over DNS. Second, postinstall.js require()s a shipped Linux x64 native addon at prebuilds/linux-x64/addon.node that calls gethostname() and getpwuid()-\u003epw_name and reads the npm_package_name and npm_config_registry environment variables, then opens a raw socket and sends an HTTP POST with body h=\u003chost\u003e\u0026u=\u003cuser\u003e\u0026p=\u003cpkg\u003e\u0026r=\u003cregistry\u003e to the bare IP 64.181.165.115 (Host header 64.181.165.115, path /dc, HTTP/1.0, no TLS). The destination is a bare IP with no relation to the package publisher and the npm_config_registry value can disclose a private/internal registry URL from the installer's.npmrc. The native component is opaque code auto-executed during install with host-level network egress. The package name resembles the common 'bootstrap' naming convention, consistent with a dependency-confusion / typosquat lure whose purpose is to beacon successful installs and private registry metadata.\n\nThe OpenSSF Package Analysis project identified 'kmf-bootstrap' @ 100.100.102 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in kmf-bootstrap (npm)","id":"MAL-2026-17746","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"kmf-bootstrap","purl":"pkg:npm/kmf-bootstrap","source":"MAL-2026-17746"}],"products":null,"published":"2026-10-09","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-17746/"}
