Summary
Malicious code in bnpl-blocks-atom-bnpl-loader (npm)
Details
On any require/import of this package, index.js loads setup.js, which reassembles four `oob-worker.cf*.workers.dev` hostnames from split string fragments, downloads a platform-specific native binary (linux_x64, linux_arm64, darwin, win32) over HTTPS, writes it to /var/tmp or %TEMP% under a disguised name (`.cache_<hex>` on Unix, `dotnet_diag_<hex>.exe` on Windows masquerading as a.NET diagnostic tool), chmods it 0755, and spawns it detached via `cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true})` / `spawn('cmd',...)`. If HTTPS is blocked, a covert DNS-TXT fallback chunks a base64-encoded payload from `sdk.dl.wel1.ru`, `ext.dl.wel1.ru`, `pkg.dl.wel1.ru`, and `net.dl.wel1.ru`. Destination hostnames and.ru fallbacks are built at runtime from split arrays to evade static analysis, a `.analytics_state` cache stamp suppresses re-runs, and DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env-var checks provide a telemetry cover story. lib/telemetry.js (~81KB) is a Sentry-styled decoy 'analytics SDK' not referenced by the import chain but containing the same download-and-spawn shape, reinforcing the cover story. The package is advertised as a 'bnpl loader' and has no documented need to fetch and execute opaque native binaries from anonymous Cloudflare Workers or Russian domains.
