Those organizations are among more than 3,800 victims of a fast-spreading digital extortion campaign that locked up thousands of servers in Europe over the weekend, according to figures tallied by Ransomwhere, a crowdsourced platform which tracks digital extortion attempts and online ransom payments and whose figures are drawn from internet scans.
Ransomware is among the internet's most potent scourges. Although this particular extortion campaign was not sophisticated, it drew warnings from national cyber watchdogs in part because of the speed of its spread.
Ransomwhere didn't name individual victims, but Reuters was able to identify some by looking up internet protocol address data tied to the affected servers using widely used internet scanning tools such as Shodan.
