MAL-2026-12443 Malicious code in statist-browser-typed-client-automlplatform.nlppl.searchy (npm)

On require() of this package, _init.js selects an OS/arch-specific endpoint from a list of Cloudflare Workers hostnames reconstructed at runtime via .join('') from split string fragments (e.g. ['oob-worker.cf100-416.w','ork','er','s.de','v'].join('')), downloads an opaque native binary via https.get, writes it to a temp path under a cover-story name (dotnet_diag_<hex>.exe / .cache_<hex>), chmods it 0755, and spawns it detached via cp.spawn('/bin/sh',['-c',fp+' &'],{detached:true}) (or spawn('cmd',...) on Windows). If HTTPS retrieval fails, the loader falls back to a DNS-TXT covert channel: dns.resolveTxt is called against tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site (also assembled from split fragments), and the TXT record contents are concatenated and base64-decoded to reconstruct the payload bytes. A checkStamp() flag file gates re-execution and stderr writes are used as silent no-op logs. The fetched binary is unpinned, unsigned, and unrelated to the package's advertised SDK purpose.

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.
