On May 12, 2017, WannaCry, the biggest ransomware attack in history, spread like wildfire around the world, indiscriminately affecting PCs belonging to consumers, businesses, hospitals, and government departments. Now, nearly one year later, the same malware continues to be prevalent, reportedly hitting aircraft manufacturer Boeing recently. Since the initial attack last year, Avast has detected and blocked more than 176 million WannaCry attacks across 217 countries. In March 2018 alone, we blocked 54 million WannaCry attacks.
