Announcing AntiSpoof-Pro: The Unfair Advantage Your Server Deserves

For the past several months, I've been working tirelessly on something revolutionary. The free version of AntiSpoof was great at what it did, analyzing client brands and plugin channels. But I knew we could go deeper. I knew we could create something so advanced, so precise, that it would change the game for server security.

That something is AntiSpoof-Pro, and it's available now.

AntiSpoof-Pro is not just another simple update, it's a complete evolution. It includes everything you love about the original, plus our new, proprietary Deep-Probe Module, a technology you won't find in any other plugin on the market.

What is the Deep-Probe Module?

This is our secret weapon. While other plugins only see the "mask" a player is wearing (their client brand and channels), the Deep-Probe Module intelligently and invisibly tests the client's underlying behavior. It can:

• Detect Hidden Mods: Uncover modifications that a client is actively trying to hide.
• Expose Inconsistencies: Catch cheaters who spoof their brand but forget to fake their behavior, creating logical contradictions that only a tampered client would produce.
• Verify Client Integrity: Run "digital sobriety tests" to ensure the client isn't just lying about its identity, but is actually a legitimate, functioning Minecraft client.

This isn't just another layer of protection; it's an entirely new dimension of it. It doesn't replace your existing anti-cheat; it complements it, catching the threats that traditional anti-cheats were never designed to see.

To continue development and protect the proprietary technology that makes this possible, AntiSpoof-Pro is now a premium, closed-source plugin.

A Final Update for Our Free Users (v1.2.7)

I know that not everyone is in a position to purchase a premium plugin. As a thank you to the community that got me here, I am releasing one final update for the free version of AntiSpoof.

Update v1.2.7 - The Legacy Edition

This final free release is a significant one. While it does not contain the new Deep-Probe Module, it delivers on a long-requested feature:

• ✅ Backwards Compatibility: AntiSpoof now officially supports servers and clients from 1.8 all the way to 1.21+!

This has been a massive undertaking, ensuring that even older servers can benefit from robust brand and channel detection.

The Future of the Free Version

Version 1.2.7 will be the final update for the free, open-source version of AntiSpoof. The GitHub repository will be archived, meaning the code will remain publicly available for you to view and use under its license, but it will no longer receive updates, bug fixes, or new features.

All future development, support, and innovation will be focused exclusively on AntiSpoof-Pro.

A Personal Note and A Heartfelt Thank You

Making the decision to transition to a premium model was not easy. As a student, the time and effort required to develop and maintain a project of this complexity, especially with the groundbreaking technology in the Pro version, is immense. This transition allows me to dedicate the resources needed to keep AntiSpoof-Pro on the cutting edge and continue providing you with the best security tools possible.

I am incredibly grateful to every single person who has been a part of this journey. For those who have been with me from the start, I hope you can understand and respect this decision. I built this because I'm passionate about server security, and I can't risk having the unique methods of the Deep-Probe Module become open source and instantly bypassed.

For those of you who make the jump to Pro, I promise you won't be disappointed. You're getting a tool that will give you an unparalleled advantage.

Thank you all, once again.

Sincerely, GigaZelensky

AntiSpoof 1.2.6 — MiniMessage + Hex update

What’s new (in a nutshell)

• Hybrid colour parsing – New MessageUtil.miniMessage() lets you send one string that mixes:

  • MiniMessage tags (<gold><bold>Hello</bold></gold>)
  • Legacy & codes (&aGreen)
  • Hex formats &#FFAA00 or &x&F&F&A&A&0&0

• Adventure-MiniMessage library added (adventure-text-minimessage 4.21.0) and version bumped to 1.2.6.

• All admin/update/chat alerts now route through MessageUtil, so you can put gradients, bold, italics, etc. directly in your config or code.

• Safer URL handling (URI.create(...).toURL()) and a small field cleanup in AntiSpoofPlugin.

How to use it

alert-message: "<gradient:#55ffff:#0055ff><bold>[AntiSpoof]</bold></gradient> <reset>&e%player% flagged! &cVanilla client with plugin channels"

Drop the new jar in place of 1.2.5, no config changes required.

Thanks to @HonzasikCZ for the suggestion!

Full Changelog: 1.2.5...1.2.6

4 Tiny patches, big sigh of relief.

---

• 💤 No more vanilla false‑positives – we ignore the builtin minecraft:brand channel now.
• 🧹 Strict mode is strict again – non‑vanilla clients can’t sneak past.
• 🔨 Fixed the punishment picker grabbing the wrong violation.
• 🗄️ Cleaned up some messy variable scope and bumped the version in pom.xml.

No config changes. Drop the new jar in, reboot, done.

Full diff → 1.2.4…1.2.5

Cheers and happy admining!

Brought to you by @GigaZelensky with ☕ and rage.

(Lite version down below without shading PacketEvents, requiring PE 2.8.1-SNAPSHOT)

Updated PacketEvents and added empty brand check

To support 1.21.5 servers, I have added support for the latest PacketEvents snapshot (2.8.1-SNAPSHOT), and added a new config value for detecting clients sending an empty brand by default.

Config changes are not necessary but I would suggest adding the new value in the config if you are coming from an older version.

AntiSpoof v1.2.3 - Changelog

Added

• /antispoof runcheck command to manually trigger brand/channel checks on players.
• Detection for missing required brand channels.
• Additional dependency handling in pom.xml.

Fixed

• Webhook formatting issues.
• Vanilla variation detection inconsistencies.
• Config typo.

Changed

• Internal detection improvements for better spoofing identification.
