Description
The npm package 'checkout-input-card-logic' version 35.8.8 contains malicious code that, upon import, downloads and executes a platform-specific binary from obfuscated Cloudflare Workers subdomains. The binary is fetched without integrity verification, saved under deceptive filenames in temporary directories, given executable permissions, and executed detached from the parent process. This behavior constitutes a supply-chain dropper disguised as unrelated checkout logic.
