Hackers have attacked the vaccination registration system in one of Italy’s largest regions, temporarily blocking residents from booking new vaccination appointments, officials said.
Residents of Lazio, which includes Rome, won’t be able to book new appointments for several days, the region’s president, Nicola Zingaretti, posted Monday on Facebook.
While the hackers’ identity and motivations weren’t immediately clear, the incident appeared to be a ransomware attack, said Allan Liska, an analyst who analyzes such attacks for the cybersecurity firm Recorded Future.
