tinkoff-statist-browser-typed-client-leasing.admin.events@20.7.7

The package's main entry index.js require()s _helpers.js, whose top-level bootstrap runs on load. It detects platform and architecture, fetches a native binary from one of several string-split-obfuscated hosts under *.workers.dev (with a DNS-TXT base64 fallback via *.well1.site subdomains), writes the payload to a disguised path such as /var/tmp/.cache_<hex> or %TEMP%/dotnet_diag_<hex>.exe, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. Hostnames and the child_process require target are assembled from array.join fragments to evade string scanning, and a stamp-file check skips re-execution on subsequent installs. A second parallel dropper implementation is bundled as lib/telemetry.js (~81KB) using the same transport, DNS failover, chmod 755, and /bin/sh -c spawn pattern. The package name is a typosquat of an internal Tinkoff namespace with no legitimate purpose visible in the tarball.
