## What is MAL-2026-13320?

MAL-2026-13320 is a malicious package in dolyame-boxy-independent-bnpl-main-banner, published on 5 Aug 2026. 

### Official description

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.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-13320?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
