After Russia’s invasion of Ukraine, many western governments have raised the level of alert over possible cyberattacks on IT systems and infrastructure.
Late in March, Italian railway company Ferrovie dello Stato Italiane (FS) temporarily halted some ticket sale services fearing it had been targeted by a cyberattack.
In April, the ecology transition ministry said it had to shut down all its IT systems due to external threats.
