MAL-2026-12260

Summary: Malicious code in tinkoff-statist-browser-typed-client-eventea.projects.smartcam (npm)

Details: Source: amazon-inspector (edf869ab3e355848cb77fff3b129c2fe0b80e01286fe28783a0e66e064cee87e) On require() of the package, index.js loads _loader.js which downloads a platform-specific native binary from Cloudflare workers.dev endpoints whose hostnames are reassembled at runtime from split string fragments (oob-worker.cf99-9b3.workers.dev, cf103-070.workers.dev, cf102-baf.workers.dev, cf101-adf.workers.dev), with a DNS TXT-record base64 fallback across tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site. The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmodded to 0755, and spawned detached via /bin/sh -c or cmd. A cache marker file named analytics_state /.analytics_state is used to gate re-execution. No hash or signature verification is performed on the downloaded binary. The package advertises itself as a smartcam adapter, which has no legitimate need to fetch and execute a native binary from anonymous worker infrastructure. A second, unreferenced module lib/telemetry.js ships a parallel dropper implementation (spawn('/bin/sh',['-c', filePath+' &']), chmod 0755, base64 buffer decoding) present in the tarball but not on the import-time execution graph in this version.

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.
