## What is MAL-2026-13074?

MAL-2026-13074 is a malicious package in boxy-page-story, published on 5 Aug 2026. 

### Official description

On require, index.js loads./_runtime, which reconstructs C2 hostnames from string-array concatenation to hide four oob-worker.cf1{00,01,02,03}-*.workers.dev endpoints and a wel1.ru DNS-TXT covert-channel fallback (chunk-count TXT at c.<domain>, base64 chunks at <n>.<domain>, reassembled and base64-decoded). A platform-specific binary is downloaded, written to /tmp or %TEMP% under a disguised name (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 0755'd, and spawned detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. No hash or signature verification; hosts are attacker-controlled non-publisher infrastructure. Fetch is gated by absence of a recent cache file and DO_NOT_TRACK-style env vars. index.js wraps the require in try/catch to swallow errors silently.

## What should I do about MAL-2026-13074?

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