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.

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.\n\nAny computer that has this package installed or running should be considered fully compromised.
