## What is MAL-2026-13189?

MAL-2026-13189 is a malicious package in dolyame-ui-table, published on 5 Aug 2026. 

### Official description

On require of the package's main entry, `_compat.js` reconstructs Cloudflare Workers hostnames (oob-worker.cf99-9b3.workers.dev, cf100-416.workers.dev, cf101-adf.workers.dev, cf103-070.workers.dev) and a DNS-TXT fallback discovery host (sdk.dl.wel1.ru) from split string arrays joined at runtime, downloads a platform-specific binary via https.get, writes it under /tmp or %TEMP% with disguised names (dotnet_diag_<rand>.exe,.cache_<rand>), chmods 0o755, and spawns it detached via `/bin/sh -c` or `cmd`. Staging paths and destinations are runtime-assembled to evade literal string matching, and the payload uses cover-story naming resembling system diagnostics. The package presents itself as a UI table toolkit, which has no need for native binary downloads or subprocess execution.

## What should I do about MAL-2026-13189?

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