On require of the package, index.js loads platform.js, which assembles attacker-controlled hostnames via array-split-and-join obfuscation (oob-worker.*.workers.dev variants and sdk/ext/pkg/net.dl.wel1.ru), fetches a platform-specific binary over HTTPS with a DNS-TXT base64 fallback channel, writes it to /var/tmp or %TEMP% under disguised names such as.cache or dotnet_diag_.exe, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe. Cover-story identifiers such as analytics_state and a DISABLE_TELEMETRY opt-out are used to frame the behavior as telemetry. The package name impersonates a Russian BNPL partner integration, and none of the shipped code implements that stated purpose.
