Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to kmf-bootstrap@100.100.101. The same advisory and Firewall decision cover these 3 recorded versions: 100.100.100, 100.100.101, 100.100.106. - Avoid installing kmf-bootstrap@100.100.101. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On npm install, the package's postinstall script performs two exfiltration actions. First, it reads the installer's hostname and npm\_package\_name and issues DNS resolutions for a label of the form \.\.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()-\>pw\_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=\&u=\&p=\&r=\ 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. \#\# Source: ossf-package-analysis (4a4e085f9bdddf6800e613b7cdfeb6b2481b2fe9bf0ccb2a5b1bffad9538194b) The OpenSSF Package Analysis project identified 'kmf-bootstrap' @ 100.100.102 (npm) as malicious.
