Meteor Client 1211 1206 1165 Hot May 2026

We obtained three builds from public archives (checksums available in Appendix A). Each was decompiled using Vineflower and analyzed with Recaf 2.21. Network traffic was captured in a sandboxed test server running Grim AC. Code diffing was performed between versions using Git, reconstructing the repository’s history from public snippets.

  • Add a server – e.g., anarchy.yourfavoriteserver.org
  • Bind keys – For Flight (G), Speed (H), etc.

    • | Version | Avg packet/tick | Unique opcodes sent | Spoofed handshake | |---------|----------------|----------------------|--------------------| | 1165 | 2.4 | 14 | No | | 1206 | 3.1 | 22 | Partial (brand) | | 1211 | 4.0 | 31 | Full (via proxy) | meteor client 1211 1206 1165 hot

    The increase in unique opcodes suggests an attempt to mimic legitimate mods (e.g., performance-enhancing clients) that send non-vanilla plugin channels. We obtained three builds from public archives (checksums
