## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

On require of the package, index.js loads \_runtime.js which fetches a platform-specific binary from anonymous Cloudflare Workers endpoints (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT fallback to tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site, writes the payload to /tmp with a hidden dot-prefixed filename (or to the Windows temp directory as dotnet\_diag\_\<rand\>.exe), chmods it to 0755, and detached-spawns it via /bin/sh -c or cmd. Destination hostnames and API names are reassembled from split string arrays (e.g. \["oob-worker.cf102-ba","f.work","ers.d","ev"\].join(""), require("child\_" + "process")) to evade static analysis. The tarball also ships lib/telemetry.js, an 81 KB secondary loader framed as a metrics SDK that contains the same drop-chmod-spawn primitives with base64-decoded chunks; it is not on the currently reachable import graph but duplicates the dropper capability. The package name impersonates a Tinkoff internal SDK; the anonymous Cloudflare Workers infrastructure and covert DNS fallback do not correspond to any first-party backend for the claimed purpose.
