What is MAL-2026-13135?
MAL-2026-13135 is a malicious package in dolyame-ui-avatar, published on 5 Aug 2026.
Official description
On package load, index.js requires./platform.js which downloads a platform-specific binary from obfuscated Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev), with DNS-TXT fallback resolvers under *.dl.wel1.ru (sdk/ext/pkg/net). Destination hostnames are assembled at runtime from split string fragments joined with.join('') to evade static analysis. The fetched payload is written to /tmp or %TEMP% under disguised names (dotnet_diag<hex>.exe on Windows,.cache_<hex> on Unix), chmod'd to 0755, and spawned detached via /bin/sh -c or cmd.exe with stdio ignored. A marker file.analytics_state is written to throttle re-execution. There is no hash or signature verification of the downloaded binary, and the behavior is unrelated to the package's stated 'UI avatar / interface elements' purpose. The package name mimics the legitimate dolyame payment SDK ecosystem.
What should I do about MAL-2026-13135?
