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.
