### 🧬 What Is Pikabot?
Pikabot is a Windows-based malware comprising two primary components:
- **Loader**: Responsible for initial infection, it decrypts and injects the core module into memory.[zscaler.com+1zscaler.com+1](https://www.zscaler.com/blogs/security-research/technical-analysis-pikabot?utm_source=chatgpt.com)
- **Core Module**: Handles malicious activities such as executing arbitrary commands, injecting additional payloads, and establishing communication with command-and-control (C2) servers.
