Stealth, Persistence, and Python: Building Undetectable Backdoors
“Persistence is power. A one-time shell is weak. A backdoor is forever.”
How HackersvellA Trains You in Covert Access
Most malware gets detected in minutes. But we teach you to build undetectable, persistent Python backdoors.
5 Backdoor Projects That Don’t Get Caught
1. SilentShell – Obfuscated Reverse Shell
- Encrypt communication with AES
- Pack with pyarmor or UPX
- Auto-reconnect on crash
-- Add idle checks to avoid raising alerts.
2. GhostDropper – Stealth File Dropper
- Downloads payloads on trigger (not startup)
- Anti-VM and sandbox detection
- Fileless payload execution via PowerShell
-- Great for phishing campaigns and USB drops.
3. RegHooker – Registry Persistence Injector
- Adds itself to Windows startup via
HKCU - Evades AV by mimicking legit software entries
- Updates itself silently on reboot
-- Combine with DNS-based beaconing for stealth.
4. StegaSpy – Steganographic Backdoor
- Hides payloads in image files (PNG, JPG)
- Extracts & executes payload on target
- Leaves no trace in filesystem
-- Extend with LSB steganography for better hiding.
5. TaskHijack – Process Injection Backdoor
- Injects shellcode into legit processes (e.g., explorer.exe)
- Uses ctypes to manipulate memory
- Remains active after user logs out
-- Add watchdog to relaunch if killed.
Your Final Phase @ HackersvellA: Evade, Persist, Control
Students will master:
- AV evasion techniques
- Process injection and UAC bypass
- Building full APT-style backdoors
You’ll leave footprints only if you want to.
