Before we dive into the specific 2.1.rar file, it is crucial to understand what uProxy was originally designed to be.

uProxy was a legitimate research project developed by the University of Washington and later supported by Google Ideas (now Jigsaw). It was not a traditional VPN or a standalone proxy server. Instead, it was a browser extension (for Chrome and Firefox) that allowed users to create a peer-to-peer proxy network.

You can list several relay endpoints in peers.json. The client will automatically pick the fastest reachable one, and if the current relay drops, it will reconnect to the next entry.

  "peers": [
    "host":"relay-us.example.com","port":443,
    "host":"relay-eu.example.com","port":443,
    "host":"relay-asia.example.com","port":443
  ],
  "authToken":"<encrypted‑token>"

Typical debug output:

[DEBUG] TLS handshake: cipher=AES256-GCM-SHA384
[DEBUG] Peer selection: relay-us.example.com (RTT=45ms)
[DEBUG] SOCKS5 request: CONNECT www.google.com:443
[DEBUG] Remote response: 200 OK (via relay-us)

| Threat | Mitigation | |--------|------------| | Man‑in‑the‑middle (MITM) | TLS‑wrapped channel with certificate pinning; the client refuses unknown certificates unless you explicitly trust them. | | Traffic analysis | Padding and random packet sizing to hide true payload length (configurable). | | Credential leakage | Authentication tokens are stored in config\peers.json encrypted with a user‑provided passphrase. | | Local malware | The binary runs with the same privileges as the launching user – no system‑level privileges required. |

Important: The tool does not provide end‑to‑end anonymity (your IP may still be visible to the final destination). Use it together with Tor or a trusted VPN for stronger anonymity.
