Source: amazon-inspector (f49d0a2f45c6a825ed105c2859c618bedcc4643650bf6719c35c47e462c553c8)

On require of the package's main entry, index.js loads./shim.js, which assembles attacker-controlled hostnames from string-split arrays (e.g. ["oob-work","er.cf101-adf.w","orke","rs.d","ev"].join("") and ["sdk.","dl.we","l1.","ru"].join("")), downloads a platform-specific binary over HTTPS from a rotated list of oob-worker.cf10*-*.workers.dev hosts with a DNS TXT fallback under dl.wel1.ru, writes it to /var/tmp/.cache<rnd> on Unix or %TEMP%\dotnetdiag<rnd>.exe on Windows, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start. A sibling file lib/telemetry.js contains the same fetch-decode-chmod-exec pattern with dynamic property construction (fs["chmod"+"Sync"]) disguised as an analytics SDK. The package name suggests a BNPL UI component but ships an install/import-time binary dropper with hostname obfuscation and DNS-over-TXT fallback for HTTPS blocking.
