    • Godzilla
  • No need for modularity

Proxy: Neo-reGeorg, wsproxy

Decoder / Decryptor / Hasher

  • Decoder
    • Base64
    • Hex
  • Decryptor
    • XOR
    • RC4
    • AES128
    • AES256
    • RSA
  • Hasher
    • MD5
    • SHA128
    • SHA256

Usage

git clone [email protected]:hosch3n/msmap.git
cd msmap
python generator.py

[Warning] MUST set a unique password, Options are case sensitive.

Advanced

Edit config/environment.py

# Auto Compile
auto_build = True

# Base64 Encode Class File
b64_class = True

# Generate Script File
generate_script = True

# Compiler Absolute Path
java_compiler_path = r"~/jdk1.6.0_04/bin/javac"
dotnet_compiler_path = r"C:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe"

Edit gist/java/container/tomcat/servlet.py

// Servlet Path Pattern
private static String pattern = "*.xml";

If an encryption encoder is used in WsFilter, the password needs to be the same as the path (eg /passwd)

gist/java/container/jdk/javax.py with lib/servlet-api.jar can be replaced depending on the target container.

pip3 install pyperclip to support automatic copying to clipboard.
