## What is MAL-2026-12527?

MAL-2026-12527 is a malicious package in cards-forms-credit-clone, published on 5 Aug 2026. 

### Official description

On require('cards-forms-credit-clone'), index.js loads _compat.js which downloads a platform-specific binary from obfuscated Cloudflare workers.dev hosts assembled at runtime via string-split concatenation (e.g. ['oo','b-worker.c','f101-adf.workers.dev'].join('')), with a DNS-TXT base64 fallback resolver at sdk.dl.wel1.ru. The fetched binary is written to /var/tmp or %TEMP% under disguised names (.cache_<hex> / dotnet_diag_<hex>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. No pinning, no hash or signature verification; comments frame the behavior as 'analytics'/'telemetry'. Hostname fragmentation and DNS-TXT covert-channel resolution are evasion patterns unrelated to the package's advertised 'cards forms' purpose. Any installer that requires this package is subjected to remote code execution under attacker control.

## What should I do about MAL-2026-12527?

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