The most common cybersecurity threats include phishing attacks, ransomware, malware, and insider threats. Phishing involves deceptive emails to steal credentials, while ransomware encrypts your data until a ransom is paid. Malware can cause widespread damage, and insider threats occur when employees intentionally or unintentionally compromise security.
