The Major Ransomware Attacks of 2017 and Tips to Prevent Yourself from Being a Victim

Ransomware dominated the cybersecurity landscape in 2017. Major attacks such as WannaCry, Petya, and Locky were mostly widespread worldwide. Victims including organizations like hospitals, schools and airports and individuals have paid over millions of dollars for ransom to unlock encrypted files. Cybercriminals will continue to exploit the same vulnerabilities in increasingly malicious ways in 2018. The newly reported ransomware Gandcrab could be a sign. Users need to keep an eye on new infections and learn to protect themselves.
