The package advertises itself as a Chrome DevTools debug proxy; that stated purpose has no need for shell reconnaissance or beaconing to a third-party request-inspection service. The combination of automatic install-time execution, capture of installer-side identity data, and a hardcoded non-first-party exfiltration endpoint matches the reconnaissance/beacon shape of a malicious postinstall payload.","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 debug-proxy-chrome-devtools (npm)","id":"MAL-2026-13948","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":"debug-proxy-chrome-devtools","purl":"pkg:npm/debug-proxy-chrome-devtools","source":"MAL-2026-13948"}],"products":null,"published":"2026-08-13","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-2026-13948/"}
