Ransomware has proven to be the most damaging malware type in history. The WannaCry ransomware nets its authors an estimated $4 billion in profit last year from the ransom payments of the victims. This time around, the Bristol International Airport is in the headlines, as the new victim of ransomware, as its flight information screens fail to display flight departure and arrival for 48-hours. Bristols spokesman: We believe there was an online attempt to target part of our administrative systems and that required us to take a number of applications offline as a precautionary measure. That was done to contain the problem and avoid any further impact on more critical systems.”]
