Data Exfiltration
Data exfiltration refers to the unauthorized copying, transfer or retrieval of sensitive data from a computer or network to an external location. This can be done using various methods such as email, file transfer, removable storage devices or even social engineering techniques.
Imagine you have a secret toy collection hidden in your room. Someone comes in and copies down the list of all your toys without your permission. They might do this by writing it down on paper, taking a photo with their phone, or even memorizing it. This is similar to data exfiltration in the computer world.
Hackers or cybercriminals might use data exfiltration to steal your personal information, financial details or even company trade secrets. This can lead to identity theft, financial loss or reputation damage.
Therefore, it’s important to regularly monitor your network for unusual activity, encrypt sensitive data, and use strong passwords to prevent data exfiltration.
