Hostnames are assembled by array-join string concatenation and child_process is loaded via require("child_"+"process") to evade static string scanning. The package advertises itself as a BNPL API SDK; the fetched binary is unrelated to that stated purpose and uses cover-story filenames (dotnet_diag,.cache_). A secondary lib/telemetry.js (~81 KB) bundles structurally identical dropper primitives (https fetch, chmod 0755, /bin/sh -c detached spawn, base64 chunk decode) though it is not reached from the current main.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
