# Data Obfuscation

#### **2. Data Obfuscation**

1. **Encoding:**
   * **Description:** Data is encoded in various formats (e.g., Base64, Hex) to hide its true content.
   * **Example:** Encoded URLs or payloads that are decoded at runtime.
2. **Data Encryption:**
   * **Description:** Data is encrypted with a key, and the key or decryption routine is hidden or obfuscated.
   * **Example:** Malware might encrypt its payload and only decrypt it when needed.
3. **Fake Data Insertion:**
   * **Description:** Inserting dummy or misleading data to confuse analysts and hide the real data or functionality.
   * **Example:** Adding irrelevant or misleading comments, variables, or functions to obfuscate the true purpose of the code.
