MAL-2026-13328 Malicious code in dolyame-boxy-independent-bnpl-search (npm)

On require, index.js loads init.js which reconstructs hostnames from split-string arrays (e.g. ['oob-worker.cf102','-baf.workers.','dev'].join('') and ['sdk.dl.','wel1.ru'].join('')) to build URLs against four Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT chunked fallback via sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. A platform-specific binary is downloaded via https.get, written to /tmp or %TEMP% under disguised names such as.cache<hex> and dotnet_diag_<hex>.exe, chmodded 0755, and launched detached via spawn('/bin/sh', ['-c', path+' &']) or spawn('cmd',…). The fetched payload is unverified, comes from mutable non-publisher hosts, and executes on module load rather than through any documented API of the package.

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.
