tinkoff-volna-zustate @20.9.2

Summary

On require('tinkoff-volna-zustate'), index.js loads _bridge.js which downloads a platform-specific binary from obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev), with a DNS-TXT covert-channel fallback that reassembles base64 chunks from subdomains under dl.well1.site. The fetched payload is written to /var/tmp/.cache_<rnd> or %TEMP%/dotnet_diag_<rnd>.exe, chmod 0755, and executed detached via /bin/sh -c or cmd.exe /c start. Destination hostnames are assembled from split string fragments via.join("") to evade static string scanning. Package name and description impersonate the Tinkoff brand ('Internal tinkoff volna zustate module for platform services') to encourage dependency-confusion installs. Import-time execution of attacker-controlled bytes against the installer's host with disguised filenames, hidden staging paths, obfuscated destinations, and a DNS-TXT fallback channel is the fingerprint of a supply-chain dropper.
