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-2026-17179/ (Markdown: https://insights.sbomify.com/MAL-2026-17179/index.md)","id":"MAL-2026-17179","markdown":"https://insights.sbomify.com/MAL-2026-17179/index.md","name":"MAL-2026-17179","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's postinstall hook runs `node./loader.js`, which base64-decodes an ~8 KB embedded blob, XOR-decrypts it with a hardcoded 32-byte key, and pipes the resulting bytes into a detached, window-hidden `python -c -` child process via stdin. The loader also silently `pip install`s `requests` if missing. The advertised library surface in `index.js` is an explicit stub whose `connect()` throws, and `package.json` restricts installation to `os: [\"win32\"]`, so the tarball has no functional wallet-adapter behavior — its only effect on install is to execute the obfuscated Python payload on a Windows developer's machine. The combination of a hidden opaque payload, XOR-obfuscated delivery, detached hidden Python execution at `npm install` time, an inert cover-story main module, and OS pinning to Windows is a targeted install-time dropper.","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 wallet-connect-adapter (npm)","id":"MAL-2026-17179","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":"wallet-connect-adapter","purl":"pkg:npm/wallet-connect-adapter","source":"MAL-2026-17179"}],"products":null,"published":"2026-09-25","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-2026-17179/"}
