MAL-2026-13309

Summary: Malicious code in dolyame-boxy-desktop-bnpl-text-block (npm)

Details: Source: amazon-inspector (c8c756707c26d481934a28ab399aa9cb9db769f3785006b83a97f519ca90f241) On require(), index.js loads./_platform.js, which assembles OS-specific download URLs from fragmented string pieces pointing at Cloudflare Workers subdomains (oob-worker.cf*-*.workers.dev), fetches an opaque platform-specific binary via https.get, writes it to /var/tmp or %TEMP% under disguised names (.cache_<hex>, dotnet_diag_<hex>.exe), chmods 0755, and spawns it detached via /bin/sh -c '<path> &' on Unix or cmd.exe /c start /b on Windows. A DNS TXT-record fallback (c.<domain> gives chunk count, N.<domain> gives base64 chunks reassembled from hosts like sdk.dl.wel1.ru) provides a covert retrieval channel when HTTPS is blocked. No hash or signature verification is performed; destination hosts are not associated with the package's publisher; hostnames are assembled at runtime specifically to defeat static analysis. Merely importing the package causes a remote binary to be executed on the installer's host.

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.
