The 'tinkoff-volna-zustate' npm package (version 20.9.2) acts as a supply-chain dropper by executing attacker-controlled code immediately upon import. It downloads a platform-specific binary payload from obfuscated Cloudflare Workers URLs and a DNS-TXT covert channel fallback, reassembling base64 chunks from subdomains to evade static detection. The payload is saved under hidden staging paths in temporary directories, given executable permissions, and executed detached via shell commands. The package name and description impersonate the legitimate Tinkoff brand to facilitate dependency confusion attacks. This behavior indicates a deliberate attempt to fully compromise the host system, enabling attackers to gain persistent control and access to sensitive information.

Any system with this package installed or running is considered fully compromised. Attackers gain full control over the host, potentially accessing all stored secrets and keys. The malicious payload executes with elevated privileges and persists beyond package removal, making remediation difficult. This poses a severe risk to confidentiality, integrity, and availability of affected systems.

Immediate removal of the 'tinkoff-volna-zustate' package version 20.9.2 is required. All secrets and keys stored on the compromised system should be rotated from a separate, trusted machine. Due to the full compromise risk, a full system forensic analysis and potential reimaging may be necessary. No official patch or fix is available; remediation relies on removal and secret rotation. Monitor for any suspicious activity related to this package and avoid installing similarly named packages that impersonate trusted brands.
