The president of Costa Rica says his country is “at war”, as cyber-criminals cause major disruption to IT systems of numerous government ministries. The Conti ransomware cartel, which is thought to be run from Russia, has upped its ransom demand to $20m. On Wednesday, the Costa Rican Treasury told civil servants that the hack had affected automatic payment services. It warned that they would not be paid on time, and would need to apply for their salaries by email, or on paper by hand. How risky is the internet nowadays ?
