Secure Rooting Procedures​

Recommended Tools​

• Magisk (most secure root solution currently available)
• TWRP (custom recovery for flashing)

Step-by-Step Rooting​

1. Unlock bootloader (wipes device):
   

   fastboot oem unlock

2. Flash custom recovery:
   

   fastboot flash recovery twrp.img

3. Install Magisk:
   • Patch boot image or flash via TWRP
   • Enable "Hide Magisk" option
4. Verify root isolation:
   • Use Shelter or Island to create work profiles
   • Configure Magisk DenyList for sensitive apps

Hardening Rooted Devices​

Essential Security Tweaks​

1. SELinux Policies:
   

   setenforce 1 # Keep SELinux enforcing

2. Firewall Configuration:
   • Use AFWall+ (requires root)
   • Block all by default, allow only needed connections
3. Secure DNS:
   

   settings put global private_dns_mode hostname
   settings put global private_dns_specifier dns.adguard.com

4. Kernel Hardening:
   • Install Kernel Adiutor
   • Enable:
     • KASLR
     • SELinux strict mode
     • Secure boot verification

Spoofing Techniques​

Device Fingerprint Spoofing​

1. Using Xposed Modules:
   • XPrivacyLua (configure per-app restrictions)
   • Device ID Changer
2. Manual Spoofing:
   

   # Change device properties (temporary)
   setprop ro.product.model "Generic Device"
   setprop ro.product.manufacturer "Generic Manufacturer"

3. MAC Address Randomization:
   

   ip link set wlan0 down
   macchanger -r wlan0
   ip link set wlan0 up

GPS Spoofing​

1. Using Mock Locations:
   • Enable developer options
   • Set mock location app (e.g., Fake GPS)
   • Configure route simulation for realistic movement
2. Low-Level Spoofing:
   • Use Xposed modules to bypass mock location detection
   • Modify gps.conf for custom NTP servers

Proxy Operations​

Secure Proxy Chains​

1. SSH Tunneling:
   

   ssh -D 8080 -C -N user@proxy-server

2. Tor Integration:
   • Orbot for transparent proxying
   • Configure apps through Orbot's VPN mode
3. Multi-Hop Proxy:
   

   # Using redsocks + iptables
   iptables -t nat -A OUTPUT -p tcp -j REDIRECT --to-port 12345

VPN Solutions​

1. WireGuard Configuration:
   

   # Generate keys
   wg genkey | tee privatekey | wg pubkey > publickey

2. Split Tunneling:
   • Route only sensitive traffic through VPN
   • Use VPN profiles for different purposes

Secure Workflows​

Compartmentalization​

1. Work Profiles:
   • Shelter (FOSS)
   • Island (by Oasis Feng)
2. Virtual Machines:
   • VMOS Pro (rooted virtual environment)
   • Set up different VMs for different ops

Secure Communication​

1. Session Isolation:
   • Use separate browsers for different activities
   • Firefox Focus for disposable sessions
2. Encrypted Storage:
   

   # Encrypt directories with ecryptfs
   mount -t ecryptfs /path/to/secret /path/to/mount

Detection Evasion​

Root Hide Techniques​

1. Magisk Hide:
   • Configure DenyList properly
   • Use Shamiko module for enhanced hiding
2. Zygisk Detours:
   • Modify app behavior at runtime
   • Bypass root detection methods
3. Environment Sanitization:
   

   # Check for root artifacts
   find / -name "*su*" -exec rm -rf {} \;

App-Specific Bypasses​

1. Banking Apps:
   • Use LSPosed with Hide My Applist
   • Disable developer options when needed
2. Games:
   • Kernel-level hide (KernelSU)
   • SafetyNet/Play Integrity bypass

Cleanup Procedures​

Secure Wipe​

1. Factory Reset++:
   

   # Overwrite empty space
   dd if=/dev/urandom of=/sdcard/temp.bin bs=1M count=1024
   rm /sdcard/temp.bin

2. Full Disk Encryption:
   • Enable before sensitive operations
   • Wipe encryption key for instant secure erase

Log Sanitization​

1. System Logs:
   

   logcat -c # Clear logs
   rm -rf /data/local/tmp/*

2. App Artifacts:
   • Clear all app caches
   • Wipe thumbnails and temporary files

Final Notes​

• Always maintain operational security (OpSec)
• Regularly update tools and patches
• Never use personal accounts for sensitive operations
• Consider burner devices for high-risk activities

Remember: The most secure system is the one you don't use recklessly. Always assess risks and maintain proper operational discipline.
