The npm package 'tinkoff-volna-zustate' version 20.9.2 is a malicious supply-chain dropper that impersonates the Tinkoff brand to trick users into installing it. Upon import, it loads a script that downloads a platform-specific binary from obfuscated Cloudflare Workers hosts, using a DNS-TXT covert channel fallback to evade detection. The payload is saved to temporary directories with disguised filenames, made executable, and launched detached from the main process. This results in full compromise of the host machine, potentially exposing all stored secrets and keys. Removal of the package does not guarantee eradication of the malware due to the extent of control gained by the attacker.
