Computer systems from the Ukraine to the United States were affected last week by the Petya cyber attack. It’s similar to the recent WannaCry ransomware attack last month.
The WannaCry ransomware took advantage of vulnerabilities in the older versions of Windows that allowed the infection to spread. All someone needed to do was click a malicious link and—bang!—they were infected. That is, if they hadn’t installed the patches and updates.
