In another cyberattack on a healthcare system, threat-actors have tried to throw a wrench into the ongoing COVID-19 vaccine roll-out in the region of Lazio, Italy. The large and densely populated region is the country’s second most populous and includes the country’s capital, Rome.
On Sunday the Facebook page of the region informed the public that hackers had disabled the systems of the regional health care agency.
Only 10 hours later the region communicated through the same channel that standing vaccination appointments could proceed as planned. But it was not yet possible to make new appointments. Later it turned out that besides the vaccination appointment system, more of the region’s systems had suffered from the attack.
Details of the attack are sparse, most likely because the investigation is still ongoing. The Facebook page mentions a “virus” but this could be the result of a common misconception where many people call every malware a virus. But there is no mention anywhere about a ransom either, which you would expect if this was yet another ransomware attack on healthcare or other critical infrastructure. What we do know is that it was labelled as a “powerful” attack that disabled all the region’s systems, including the information site Salute Lazio portal, which was still unreachable at the time of writing.
Unofficial sources claim to know that the attackers managed to get hold of the credentials for an administrator’s account and released a “cryptolocker” which would suggest that this was a ransomware attack, or possibly a “wiper” attack, where attackers use ransomware to scramble a target’s computer, but with no intention of asking for a ransom or providing a way to unscramble them. The investigation will be done by the Italian Postal and Communications Police Service which is the police department responsible for cybercrime.
The region’s officials have called the attackers both criminals and terrorists. The question which of the two qualifications is the most accurate is closely correlated with the nature of the attack. There have been a lot of protests in Italy against the introduction of the so-called Green Pass, which shows people have been vaccinated, tested negative or recovered from COVID-19. Based on the Green Pass, which comes into effect on 6 August, holders will have access to places where non-holders will be barred.
While some see the Green Pass as a way to increase vaccination rates and persuade the undecided, some see it as a step too far. Looking at the number of vaccination requests the persuasion technique seems to work. Which might have triggered this attack on the Lazio region’s systems. But it might just turn out to be the next ransomware or wiper attack (although this scenario would be very surprising).
Even though most IT systems were offline, some have been restored, including emergency networks, time-dependent networks, and hospital systems. The local government has reiterated that the vaccination drives would continue in spite of the attack. The vaccination appointment system for the Lazio region has been transferred to the Italian national vaccination to keep the momentum going.
The disruption of Lazio’s vaccine appointment system is just one of a number of notable and disturbing attacks against critical infrastructure in 2021.
