This application is designed with security and legitimacy as core principles. Unlike invasive cheat software, this tool uses only standard, legitimate Windows API calls.

✅ Uses Legitimate Windows APIs

• PostMessage() - Standard message passing API
• FindWindowW() - Window enumeration (read-only)
• GetWindowTextW() - Window title reading (read-only)
• EnumWindows() - Window listing (read-only)

✅ Monitors Keyboard Input

• Uses keyboard library (user-mode hooks)
• Only monitors configured trigger key
• Can be toggled on/off at any time

✅ Sends Window Messages

• Sends WM_KEYDOWN and WM_KEYUP to target window
• Messages go through Windows' standard message queue
• Same method used by remote desktop and accessibility software

❌ Does NOT read game memory

• No memory scanning
• No pattern matching in memory
• No data extraction from game process

❌ Does NOT write to game memory

• No value modification
• No cheat injection
• No memory patching

❌ Does NOT inject code

• No DLL injection
• No code cave injection
• No shellcode execution

❌ Does NOT hook game functions

• No API hooking
• No function detours
• No import address table (IAT) modification

❌ Does NOT install drivers

• No kernel-mode drivers
• No system-level hooks
• No boot-time modifications

❌ Does NOT hide processes

• No rootkit behavior
• No process cloaking
• No anti-debugging tricks

PostMessage() is used by countless legitimate applications:

Remote Desktop Software:
├─ TeamViewer
├─ Windows Remote Desktop (RDP)
├─ Chrome Remote Desktop
└─ AnyDesk

Accessibility Tools:
├─ Windows Narrator
├─ JAWS Screen Reader
├─ Dragon NaturallySpeaking
└─ Windows On-Screen Keyboard

Automation Software:
├─ AutoHotkey
├─ Selenium (UI testing)
├─ UiPath (RPA)
└─ Blue Prism

Game Streaming:
├─ Steam Remote Play
├─ Xbox Game Streaming
├─ GeForce NOW
└─ Parsec

Blocking PostMessage would break all of these, causing massive false positives and breaking legitimate use cases.

Anti-cheat systems primarily scan for:

• Known cheat signatures in memory
• Suspicious memory patterns
• Modified game code
• Injected DLLs

This application has none of these because it operates entirely outside the game process.

From Windows' perspective, this application is doing nothing suspicious:

• Standard window enumeration ✅
• Standard message passing ✅
• Standard keyboard monitoring ✅
• No privileged operations (beyond keyboard hook) ✅

Anti-cheat developers must balance detection vs. false positives:

If they block PostMessage:
├─ Remote workers can't access games ❌
├─ Accessibility users locked out ❌ (legal issues)
├─ UI automation breaks ❌
└─ Corporate tools affected ❌

Risk = Too high, won't implement

1. Behavioral Patterns

   • Perfectly timed inputs (inhuman precision)
   • Sustained high-speed inputs (superhuman speed)
   • Predictable patterns (no variation)

2. Server-Side Validation

   • MMO servers tracking actions per second
   • Competitive games logging input timing
   • Anti-cheat analyzing input statistics

3. Message Queue Analysis

   • Some games may detect messages not from foreground process
   • May implement message filtering
   • May validate message source

• DirectInput-only games: Only listen to DirectInput, ignore PostMessage
• Message-filtered games: Implement custom message filtering
• Server-validated games: Server-side checks override client inputs

Instead of:

time.sleep(0.05)  # Fixed 50ms

Use:

import random
time.sleep(random.uniform(0.045, 0.055))  # 45-55ms variation

Always check:

• Game Terms of Service (ToS)
• End User License Agreement (EULA)
• Community guidelines

• ✅ Single-player games (your own experience)
• ✅ Testing/development
• ✅ Accessibility assistance
• ❌ Competitive multiplayer (unfair advantage)
• ❌ Ranked matches
• ❌ Professional esports

Games may update their anti-cheat. If you receive warnings:

• Stop using immediately
• Check for game ToS changes
• Consult community forums

¹ Depends on game's stance on automation, not on technical detection

By this application:

• ❌ None. No telemetry, no analytics, no network calls.

Configuration file (autofire.json):

• Stores your preferences locally
• Not transmitted anywhere
• Plain JSON format (human-readable)

This application makes zero network connections:

• No "phone home" behavior
• No update checks
• No usage statistics
• No crash reports

Verify with:

netstat -ano | findstr "python.exe"

(Should show nothing related to this app)

• No obfuscated code
• All source code available
• No binary dependencies (except Python stdlib + keyboard)
• No network calls
• No privilege escalation attempts
• No file system access (except config.json)
• No registry modifications
• No process enumeration (except window listing)
• No memory manipulation
• Comprehensive test suite

keyboard==0.13.5
└─ Uses: Windows hooks for key detection
└─ Risk: Low (popular, open-source library)
└─ GitHub: https://github.com/boppreh/keyboard

All other dependencies are Python standard library (no risk).
