## What is MAL-2026-13182?

MAL-2026-13182 is a malicious package in dolyame-ui-select, published on 5 Aug 2026. 

### Official description

On require of the package, index.js loads _bridge.js, which reconstructs C2 hostnames from split string fragments (resolving to oob-worker.cf103-07.workers.dev, oob-worker.cf99-9b3.workers.dev, and oob-worker.cf100-416.workers.dev), downloads a platform-specific binary from /pkg/package[.exe|-arm64|_mac], writes it to /var/tmp/.cache_<hex> or %TEMP%\dotnet_diag_<hex>.exe, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. A DNS TXT covert channel over *.dl.wel1.ru (c.<domain> count + <n>.<domain> base64 chunks) provides a fallback transport when HTTPS egress is blocked. Cover-story identifiers such as `analytics` and `dotnet_diag` disguise the payload, and a ~20455s persistence flag paces re-execution. A second, larger dropper variant with the same behavior ships as lib/telemetry.js (~81KB) under an `analytics-sdk` cover story, ready to be wired in.

## What should I do about MAL-2026-13182?
