Costa Rican President Rodrigo Chaves has declared a state of national cybersecurity emergency after a Conti ransomware attack crippled the country’s government and economy. Conti allegedly demanded $10 million in ransom from Costa Rica in exchange for not releasing the data from the Ministry of Finance, to which the government declined to respond.

The group said it had gained access to 900 servers from which nearly 1TB worth of data was infiltrated, including 900GB of Tax Administration Portal databases and 100GB of internal documents containing full names and email addresses of those in the Ministry of Finance. 

According to local reports, several departments have remained without digital services since the attacks started on April 18. The attack also severely impacted the country’s foreign trade by disrupting its customs and taxes platforms. President Chaves said the private sector was “in crisis” as they had to conduct business manually. 

Over the past two years, the Conti ransomware group has been responsible for hundreds of ransomware incidents. To combat Conti’s ransomware attacks on Costa Rica and others, the U.S. announced it would be offering a $15 million reward for any information that may lead to the identification and arrest of the group leaders.
