The npm package sme-rko-finance-front-payment-registers-operations-domain version 35.8.1 contains malicious code that loads a runtime script which downloads an opaque platform-specific binary from hardcoded Cloudflare workers.dev subdomains. If the HTTPS download fails, it uses a covert DNS-TXT channel to retrieve and reassemble the payload. The binary is saved under disguised filenames in temporary directories, given executable permissions, and executed detached from the main process. The binary is unverified and served from anonymous infrastructure unrelated to the legitimate package publisher.
