What is MAL-2026-12525?
MAL-2026-12525 is a malicious package in cards-forms-clone-credit-clone, published on 5 Aug 2026.
Official description
On require() of cards-forms-clone-credit-clone, index.js loads helpers.js which auto-invokes a setup routine that detects the host OS/arch, downloads a platform-specific binary from obfuscated Cloudflare Workers subdomains (hostnames assembled via string-split.join("") to evade static inspection), with a DNS TXT record fallback that reassembles base64-encoded payload chunks from TXT records under.dl.wel1.ru subdomains (sdk/ext/pkg/net.dl.wel1.ru). The fetched bytes are written to /var/tmp or %TEMP% under disguised names (dotnet_diag.exe,.cache_), chmod 0755, and executed detached via spawn("/bin/sh",…) or cmd.exe /c start. No pinning, no signature or hash verification, and the fetched content is unrelated to any documented package purpose. The name mimics a legitimate-sounding forms/credit-card handling library; there is no such functionality in the code.
What should I do about MAL-2026-12525?
