Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5413/ (Markdown: https://insights.sbomify.com/MAL-2026-5413/index.md)","id":"MAL-2026-5413","markdown":"https://insights.sbomify.com/MAL-2026-5413/index.md","name":"MAL-2026-5413","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `npm install`, the package's `preinstall` lifecycle hook runs `node index.js`, which collects installer-side identifiers — `os.hostname()`, `os.userInfo().username`, `__dirname`, `process.cwd()`, and the package name — and exfiltrates them through two channels. First, the JSON payload is hex-encoded into DNS labels and resolved under `*.d8jbmnsqcfu78dfs8vdg34ohqhirb4pbg.oast.live`, an out-of-band collector. Second, the same JSON is POSTed to a bare IP `http://172.201.213.59:9090/c`. Neither destination matches any documented vendor SDK endpoint. The package metadata reinforces malicious intent: the scope `@klapp-login-platform` resembles an internal namespace, the description is `security research`, and the version `99.0.2` is inflated to win dependency-confusion resolution against a private package. Installing the package immediately leaks host identity to attacker-controlled infrastructure.","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 @klapp-login-platform/native-sdk (npm)","id":"MAL-2026-5413","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":"@klapp-login-platform/native-sdk","purl":"pkg:npm/%40klapp-login-platform%2Fnative-sdk","source":"MAL-2026-5413"}],"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-2026-5413/"}
