Admin CMD Taskkill Immunity
On startup, PrivaGuard applies a custom Discretionary Access Control List (DACL) via the native Windows SetKernelObjectSecurity API. This systematically strips PROCESS_TERMINATE (0x0001) and PROCESS_SUSPEND_RESUME (0x0800) rights from standard users and Administrators alike.
ERROR: Access is denied. Protected by Process DACL Hook.
Session 0 True System Service
Unlike basic tray apps that terminate when a user logs off or gets suspended, PrivaGuard runs as a native Windows Service under NT AUTHORITY\SYSTEM in isolated Session 0. Cross-session communication is achieved via authenticated Named Pipes with 1.5s cryptographically validated heartbeats.
Status: RUNNING • Recovery: SCM Auto-Restart (1000ms)
Self-Healing Config Shadow Vault
User configurations are hardened with NTFS Deny DELETE permissions. Multi-hive signed HMAC-SHA256 shadow backups are synced across %PROGRAMDATA% and registry hives. An active ReadDirectoryChangesW worker detects external tampering in <1ms and restores authentic state in <50ms.
Tamper Event Detected → Restored in 0.042s from Vault
Safe Mode Boot & Anti-Debugging
PrivaGuard registers within Windows SafeBoot\Minimal and Network registry hives. When SM_CLEANBOOT is detected, defensive postures escalate instantly. PE checksum verification (MapFileAndCheckSumW) and PEB BeingDebugged traps abort cracking attempts.

What Happens When Someone Tries to Snoop?
Trace the exact microsecond execution pipeline triggered when an unauthorized user attempts to open a protected app.
Target Launch Attempt
An intruder or coworker clicks your WhatsApp, Chrome, or confidential folder icon while your laptop is unattended.
Target: WhatsApp.exeKernel Window Interception
PrivaGuard's process watchdog intercepts the execution handle before the window can render sensitive messages. An impenetrable display shield blankets the target app.
AES-256 Display Shield ActiveCryptographic Authentication Challenge
User is prompted for Master Password or PIN. Credentials are hash-verified with 100,000 PBKDF2 rounds using constant-time comparison.
PBKDF2-HMAC-SHA2563x Failed Guesses → Silent Forensic Capture
If an incorrect PIN is entered 3 times, PrivaGuard calls the DirectShow camera pipeline in <1s. It captures a crisp snapshot of the snooper silently with zero shutter sound.
