The package.json declares a postinstall hook (`node src/canary.js`) which fires automatically on `npm install`. src/canary.js performs a DNS lookup and HTTPS GET to a hardcoded `96e03fa6c292469a-172-245-86-254.serveousercontent.com` subdomain — Serveo is an anonymous reverse-tunnel service, so the destination is operator-controlled and not tied to any identifiable publisher. Each install reveals the installer's public IP and DNS resolver to whoever currently controls that tunnel. Combined with the brand-impersonating name (installers may pull this expecting a legitimate Exodus SDK), the package functions as an install-time beacon against unsuspecting installers regardless of the author's stated 'research' intent.","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 exodus-ethereum-sdk (npm)","id":"MAL-2026-5440","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":"exodus-ethereum-sdk","purl":"pkg:npm/exodus-ethereum-sdk","source":"MAL-2026-5440"}],"products":null,"published":"2026-06-09","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-2026-5440/"}
