This allows *PromptLock* to map and access a victim's file system systematically.\u003C/p>\n\n\u003Cp>\u003Cstrong>2. **Sensitive Data Detection**\u003C/strong>: Using the LLM’s natural language processing capabilities, *\u003Cstrong>PromptLock\u003C/strong>* analyzes files to identify sensitive information, such as personal data, financial records, or proprietary documents. The AI’s ability to understand context makes it particularly adept at pinpointing valuable data.\u003C/p>\n\n\u003Cp>\u003Cstrong>3. **Personalized Extortion Messages**\u003C/strong>: The virus generates tailored messages for victims, detailing how their data will be handled—whether deleted, encrypted, or publicly exposed. These messages include a Bitcoin wallet address, ostensibly for ransom payments. Intriguingly, the address is linked to Satoshi Nakamoto, the pseudonymous creator of Bitcoin, suggesting it may be a placeholder or a symbolic gesture by the malware’s creator.\u003C/p>\n\n\u003Cp>\u003Cstrong>4. **Dynamic Encryption Code**\u003C/strong>: Rather than using static encryption routines, *\u003Cstrong>PromptLock\u003C/strong>* leverages the LLM to generate file-encryption code on the fly.
