By San José, Costa Rica — In a joint operation codenamed “Nexus,” Costa Rican and Colombian authorities have struck a significant blow against a sophisticated phishing ring targeting Banco de Costa Rica customers. The operation involved nine raids across Costa Rica and three in Medellín, Colombia, resulting in the arrest of one suspect in Costa Rica and the seizure of computers allegedly used in the fraudulent activities.
The criminal group is accused of creating a fake Banco de Costa Rica website to steal sensitive customer data, which they then used to transfer funds and make ATM withdrawals in Costa Rica. The fraudulent website, originating in Medellín, lured unsuspecting customers into providing their login credentials and other personal information.

The rise of cybercrime presents significant challenges to existing legal frameworks. Proving jurisdiction, identifying perpetrators, and recovering damages require international cooperation and constantly evolving investigative techniques. Businesses must proactively implement robust cybersecurity measures, not just to protect data, but also to demonstrate due diligence in legal proceedings.

The operation involved the collaborative efforts of the Organismo de Investigación Judicial (OIJ) and the Prosecutor’s Office of Costa Rica, the Colombian Cyber Police and Public Ministry, and Ameripol (the Community of Police of America).
In Medellín, it is presumed that the sites where the three raids are being carried out are places where fake pages of a Costa Rican bank were created, which, presumably, were then positioned to be found by the victims in internet searches.
OIJ Statement
Authorities have linked the group to 24 cases of fraud, totaling ₡27.5 million (approximately $54,000 USD) and $5,878 USD, between February 2023 and March 2025. While two suspects are targeted for arrest and 28 others are summoned for questioning, investigators believe the ring comprises approximately 30 individuals and are not ruling out the possibility of additional, unreported victims.
As part of the investigation, Costa Rican authorities also searched the offices of three internet service providers, seeking information relevant to the case. The Chamber of Infocommunication and Technology issued a statement confirming the cooperation of telecommunications companies with the authorities, clarifying that the raids were unrelated to the personnel or operations of these companies.
This successful operation highlights the increasing need for vigilance against online fraud. Customers are urged to exercise caution when accessing banking websites and to verify the legitimacy of any online platform requesting personal information.
The arrest and ongoing investigation signal a strong message of deterrence against cybercrime and reaffirm the commitment of Costa Rican and Colombian authorities to protect their citizens from online threats.
