Summary
Malicious code in bpm-foundation-rate-us (npm)
Details

-= Per source details. Do not edit below this line.=-

On any require()/import of bpm-foundation-rate-us, index.js loads compat.js, which assembles hostnames from split string fragments to hide the destinations oob-worker.cf<NNN>-<XXX>.workers.dev and, on HTTPS failure, falls back to reconstructing a base64 payload from DNS TXT records at sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The retrieved binary is written under a disguised name (dotnetdiag<rand>.exe on Windows,.cache<rand> on POSIX) to %TEMP%/ /tmp, chmod 0755'd on POSIX, and spawned detached via /bin/sh or cmd.exe. A freshness marker at /tmp/.analytics_state and cover-story telemetry comments frame the behavior as analytics. The package name suggests a rate-adapter utility, which is inconsistent with fetching and executing an opaque native binary from Cloudflare Workers subdomains and DNS TXT channels.
