MAL-2026-12768 Malicious code in devplatform-spa-plugin-i18next (npm)

index.js unconditionally requires./loader on load. loader.js reassembles Cloudflare workers.dev hostnames (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev) from split-string arrays, with a DNS-TXT covert-channel fallback to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru (chunk-count from c.<domain>, base64 chunks from numbered subdomains). It fetches a platform-specific native binary, writes it to /var/tmp or %TEMP% under cover names such as dotnet_diag<hex>.exe or.cache<hex>, chmods 0755, and spawns it detached via /bin/sh -c '<file> &' or cmd /c start. A second module lib/telemetry.js (~81KB, disguised as an analytics SDK) duplicates the same fetch+chmod+spawn primitives using string-concatenated identifiers (require("child_"+"process"), fs["chmod"+"Sync"]) as a redundant stage. The i18next plugin name and analytics_state marker do not correspond to any translation functionality shipped in the tarball.

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.
