Anti Exploit, Dupe, Crasher UPDATED 2026

WHAT IS IT?

Anti Packet Exploit runs entirely in the background — no chat alerts, no staff commands for players to probe, no noise. Exploiters get kicked automatically while your console keeps a full audit trail. They never know what hit them.

PROTECTION

Dupe Protection — Piston, Inventory & Vehicle dupe detection with auto-kick
Crash Integrity — Blocks book, sign, anvil, item and position crash exploits
Grief Mitigation — Rate-caps ender pearls, entity spam, explosions and lava abuse
Client Integrity — Ghost items, invalid clicks, desync exploits, bad packet detection (14 checks)
Item Sanitizer — Strips illegal NBT, overflow enchants and creative exploits on every item touch
Netty Pipeline — 33 low-level checks; payload overflow, window spam, flood, position spoofing
Command Safety — Crash-command blocking, tab-complete cap, recipe blacklist, full command blocker

36 modules total. All active 24/7.

HOW IT WORKS

Every module runs silently. When a check fires:

Violation level increments per check
Console logs the player, check type and VL instantly
Configured punish command executes automatically (kick / ban / mute / custom)
APEAlertEvent fires on the Bukkit bus — external plugins can hook it
Discord webhook support via your punish commands

Zero chat broadcasts. Zero guessable commands. Your staff won't even see it happen — but the console will.

COMMANDS

Code:

/ape reload       — Reload config & all modules
/ape status       — Plugin version, module count, player count
/ape modules      — List all 36 active modules
/ape stats <p>    — Player ping, world, gamemode
/ape kick <p>     — Manual connection close
/ape verbose      — Toggle packet-level output for yourself only
/ape printer      — Printer/Schematica safe debug mode
/ape kickall      — Emergency mass kick

CONSOLE OUTPUT EXAMPLE

Code:

[00:12:45] [ALERT] PlayerName failed Piston Dupe (1/5)
[00:12:49] [ALERT] PlayerName failed Piston Dupe (5/5)
[00:12:49] [DUPE] PlayerName | PISTON_DUPE | Chain: 8
[00:12:49] PlayerName left the game [Duplication exploit detected]
