SharPyShell is a Python tool that generates a tiny, obfuscated ASP.NET webshell for C# web applications on .NET Framework and provides an interactive encrypted-channel terminal for post-exploitation. It compiles C# and PowerShell code in memory at runtime to evade file and network signature detection.

Use cases

  • generate an obfuscated aspx webshell for a pentest engagement
  • interact with a compromised IIS server through an encrypted channel
  • run post-exploitation commands on a restricted web server with limited network access
  • perform privilege escalation and lateral movement from a webshell
  • evade IDS signatures during authorized penetration testing

When to choose

  • you are a penetration tester needing stealthy post-exploitation on an ASP.NET/IIS target
  • the compromised server has heavily restricted inbound and outbound connections
  • you need in-memory C# or PowerShell execution without dropping detectable payloads

When to avoid

  • you need a full-featured C2 framework like Meterpreter or Empire
  • your target runs VB.NET instead of C#
  • you are not operating in an authorized security testing context
