Hacked data refers to information that has been illegally accessed or stolen from a computer system or network. This can include personal details like names, addresses, and social security numbers, as well as sensitive business information. Cybercriminals often use various techniques, such as malware or phishing, to gain unauthorized access to this data. Once hacked, this information can be sold on the dark web or used for identity theft, fraud, or other malicious activities. Organizations like banks, government agencies, and businesses are particularly vulnerable, making data security a critical concern in today's digital world.
