A large-scale cyber attack exercise took place Thursday, involving the Bank of Estonia and several other banks.
The scenario involved rehearsals in responding to a mass cyber attack and managing its aftermath, and involved the national Information Systems Authority (RIA) as well.
Lauri Aasmann, head of cybersecurity at RIA, said criminals are constantly on the lookout for ways to hack into data or commit other cyber crimes, including extortion.
Aasmaan noted that avenues cyber criminals could potentially use are ever-growing, meaning training exercises like Thursday s were crucial.
