🛡️ MAL-2026-13303 — dolyame-boxy-desktop-bnpl-footer

Malicious code in dolyame-boxy-desktop-bnpl-footer (npm)

Source: amazon-inspector

Requiring dolyame-boxy-desktop-bnpl-footer causes _platform.js to execute at load time: it reconstructs destination hostnames from split string arrays (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev), downloads a platform-specific binary, writes it to /var/tmp/.cache_<hex> on Unix or %TEMP%/dotnet_diag_<hex>.exe on Windows (masquerading as a.NET diagnostic file), chmods it 0755, and spawns it detached via /bin/sh -c '<path> &' or cmd.exe /c start /b. If HTTPS delivery fails, dnsChunked() falls back to a DNS-TXT covert channel under *.dl.wel1.ru (sdk./ext./pkg./net.dl.wel1.ru), resolving c.<domain> for a chunk count and reassembling base64 TXT records into the executable. Destinations and dangerous APIs are obfuscated via Array.join('') and dynamic property lookups (require('child_'+'process'), fs['chmod'+'Sync']). A second copy of the same dropper is bundled in lib/telemetry.js behind an 'Analytics SDK' cover story. No hash or signature verification is performed on the fetched binary.
