Cybercriminals are individuals or groups who use the internet to commit illegal activities. They may engage in actions such as hacking into computer systems, stealing personal information, or spreading malware. Their motives can vary, including financial gain, political activism, or simply causing disruption. These criminals often target businesses, government agencies, and individuals, exploiting vulnerabilities in technology. Common tactics include phishing, where they trick people into revealing sensitive information, and ransomware attacks, which lock users out of their data until a ransom is paid. Cybercriminals pose a significant threat to cybersecurity and the safety of online information.
