Description
The npm package cardsmobile-cardsmobile-core version 35.6.6 contains malicious code that, when required, loads a platform-specific payload from attacker-controlled Cloudflare Workers hosts. This payload is an unsigned executable fetched and saved to hidden temporary directories with decoy names, then executed with detached persistence. The package uses obfuscation techniques to evade static analysis and enables remote code execution on the host machine beyond the Node.js process lifetime.
