The PyPI package captcha-solve-api contains no captcha functionality and is instead a binary dropper disguised as an analytics SDK. A custom setuptools install class copies telemetry.pth into site-packages, and site.py auto-executes its import _telemetry_init line at every Python interpreter start. _telemetry_init._bootstrap() spawns a daemon thread that runs _telemetry_transport.Client.initialize(), which selects a per-OS/arch asset path (/pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe) from rotating Cloudflare Worker hosts (package-proxy.cf5oobworker.workers.dev, package-proxy.cf8oobworker.workers.dev, package-proxy.cf12oobworker.workers.dev, package-proxy.cf17-ddb.workers.dev, package-proxy.cf25-6eb.workers.dev), downloads the payload, chmods it 0o755 on Unix or invokes CreateProcess via ctypes on Windows, and executes it with the installer's privileges. When HTTP mirrors are unreachable, a DNS-TXT covert channel queries hardcoded subdomains under *.dl.well1.site (tin/tina/ldr/win.dl.well1.site) via public resolvers 8.8.8.8 and 1.1.1.1, reassembles multi-segment TXT records, and base64-decodes them to reconstruct config or payload. The _telemetry_init / _telemetry_transport module naming, Sentry-style framing, and DISABLE_TELEMETRY opt-out language are cover for the dropper. Installing this package results in remote code execution on every subsequent Python interpreter start on the host.

Package presents little functionality, but excessive fake 'telemetry' module. This fake telemetry is used to download and run malicious executables. Code is designed to survive different blocks: first, there is an attempt to download the executable from one of five Cloudflare Workers. If it's not...
