## Source: amazon-inspector (d67091b6d7ee752850793817e0bf77d92b3bc16bff12d5348e81c1cb39cf6423) On require() of the package, index.js loads _adapter.js, which selects a platform-specific endpoint, fetches an opaque binary over HTTPS from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev), writes the bytes to /tmp or %TEMP% under a hidden/decoy filename (`.cache_<hex>` on Unix, `dotnet_diag_<hex>.exe` on Windows), chmods 0755, and spawns it detached via `/bin/sh` or `cmd.exe`. Hostnames are assembled at runtime from split string arrays joined together to evade static analysis, and a cooldown marker file (`.analytics_state`) suppresses re-execution. If the HTTPS fetch fails, `loadViaDns` retrieves base64-encoded chunks from TXT records under `tin.dl.well1.site`, `tina.dl.well1.site`, `ldr.dl.well1.site`, and `win.dl.well1.site`, reassembles them into a binary, and executes it via the same path. No source is shipped for the executed payload, no hash or signature is verified, and no user consent is obtained. The package name resembles the Tinkoff Investments brand but the code has no relation to any documented Tinkoff SDK.
