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.\n","affected":[{"package":{"ecosystem":"npm","name":"wallet-connect-adapter"},"versions":["1.4.2"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"loader.js","sha256":"659956d8936ad347f41c1af3831d301e90f743eaf49596e3aa223defcf82c945","tlsh":"a1429fa53c3ae839223186fc1a7716e8125fc454566ee0c0b6cd8af6ed95cf85e770c1"},{"path":"index.js","sha256":"dd8bd3467ca1c7cb2e9c8beebbd5f89255af044dc54cf2054db1add7f35b38a3","tlsh":"0ad0722d927693b0030b2140880adc50e7f84030a22196800a84c2989024e8ccaa27ca"}],"package_integrity":[{"filename":"wallet-connect-adapter-1.4.2.tgz","hashes":{"sha1":"dfd8d0539f7adb0500f6b4ac3f03aafb956766ab","sha512_sri":"sha512-wLZ9LvWp03ifk0O4tv5Js+VU/JsButlHGIMbpaiXTu8RRGoalIsJyK2W/gI4Yr1GS6h0pV7zLirhEMSAY+pxow=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/wallet-connect-adapter/v/1.4.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-020531","import_time":"2026-09-25T02:45:28.52017284Z","modified_time":"2026-09-25T02:38:56Z","sha256":"4135dd91724bdca6fc36f3a49906d219acc67afde7802cb1bd114d128984ca3d","source":"amazon-inspector","versions":["1.4.2"]}]}}
