## What is MAL-2026-12288?

MAL-2026-12288 is a malicious package in twork-data-services-aggregator-sme-task-info, published on 5 Aug 2026. 

### Official description

On require of this package, index.js loads _runtime.js which asynchronously fetches a platform-specific binary from string-concatenation-obfuscated hosts (oob-worker.cf100-cf103-*.workers.dev, with a DNS-TXT chunked base64 fallback via tin/tina/ldr/win.dl.well1.site), writes it to /tmp as.cache_<rand> or to %TEMP% as dotnet_diag_<rand>.exe, chmods it 755, and spawns it detached via /bin/sh -c or cmd.exe /c start. Destination hostnames and DNS resolvers are assembled at runtime via.join() over split string fragments to evade static inspection. No hash or signature verification is performed on the fetched bytes. A second, functionally equivalent dropper is shipped in lib/telemetry.js (mislabeled 'Analytics SDK'): base64 chunk reassembly, split-string require("child_"+"process"), fs["chmod"+"Sync"](path, 0o755), and cp.spawn("/bin/sh", ["-c", filePath+" &"], {detached:true}). Package name masquerades as an enterprise data-services utility; behavior is a load-time remote-code-execution dropper.

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.

## What should I do about MAL-2026-12288?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
