Key Characteristics:
Multi-Layered Obfuscation ("Shields"): It employs a 5-stage ("shield") process. Each shield transforms the code (e.g., VBS to BAT, BAT to HTA, then back to VBS) and applies different encryption/obfuscation techniques.
Diverse Encryption/Encoding Techniques: It uses a combination of:
Custom XOR encryption (with a dynamic key).
Base64 encoding.
Zlib compression.
Caesar cipher (with a dynamic, per-character index-based shift).
Substitution cipher (with a dynamically generated substitution map).
Dynamic Key Generation: Keys for XOR, Caesar shift, and the substitution map are generated randomly each time the application runs, meaning each encrypted output is unique.
Execution Delay & Camouflage: The final script introduces a significant total delay (50 seconds, 10 seconds per shield) before the original VBS payload executes. During these delays, it runs "dummy" or "camouflage" VBS code to mimic benign activity and mislead analysts.
Anti-Detection & Anti-Reverse Engineering:
The multi-stage wrapping and varied encodings aim to evade signature-based detection.
The final VBS output has a unique, randomly generated comment appended to it, which changes its file hash, helping to bypass simple hash-based blacklisting.
Self-Contained Dropper/Loader: The output of each stage (and the final output) is a script that contains the logic to decode/decrypt the next layer and execute it, eventually running the original VBS payload.
GUI for User Interaction: Provides a simple graphical interface to upload the VBS file and shows the progress through the encryption shields.
Automatic Webpage Opening: Upon starting,
Temporary File Management: Uses a temporary directory to store intermediate files during the conversion process, which it attempts to clean up afterward.
