        2. Identify any vulnerabilities or weaknesses in the target's system, such as unpatched software or weak passwords.\n

        4. Execute the plan, either by manually entering commands or using automated tools to gain unauthorized access to the target's computer.\n
        5. Once inside the target's system, the hacker would need to navigate and locate sensitive information, such as passwords, financial data, or personal files.\n
        6. Finally, the hacker would need to cover their tracks and avoid detection by the target or authorities, which may involve using encryption, deleting logs, or using anonymizing tools.\n\n
