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 often include financial gain, political agendas, or simply causing disruption. These criminals can target anyone, from individuals to large organizations. Common tactics include phishing, where they trick people into revealing sensitive information, and ransomware attacks, which lock users out of their systems until a ransom is paid. Cybercriminals pose a significant threat to cybersecurity and the safety of online information.
