Malicious code in dolyame-boxy-independent-bnpl-main-banner (npm)

Details

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

## Source: amazon-inspector (e31cd37951ea782d9a4a5cd23ad0524d154dccddbf0aef0d96cfdcaa29d03698) index.js unconditionally requires./_bridge on load. _bridge.js selects a per-platform payload (linux x64/arm64, darwin, win32), fetches a native binary over HTTPS from a hardcoded list of Cloudflare *.workers.dev endpoints (assembled at runtime by joining split string arrays such as ["oob-worker.cf101-adf.work","ers",".de","v"]), writes it to /tmp/.cache_<uid> or %TEMP%/dotnet_diag_<uid>.exe under names that impersonate benign artifacts, chmods 0755 on POSIX via fs["chmod"+"Sync"], and spawns it detached through /bin/sh -c on POSIX or cmd.exe /c start /b on Windows. A DNS TXT covert-channel fallback resolves alternate payload sources under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru, with the discovery domains also reconstructed from split arrays. lib/telemetry.js ships a second parallel dropper implementation labelled as an "Analytics SDK" (base64 payload assembly, chmodSync 0755, /bin/sh -c spawn) that is not reached from the current index.js but is packaged in the tarball. The advertised purpose (a BNPL banner abstraction) has no relationship to fetching and executing platform-specific native executables, and the destinations are not publisher-owned.
