In April 2020 the Argentinian telecommunications provider Claro suffered a significant data breach involving its customer database. The incident originated from an unsecured server or internal system vulnerability that allowed unauthorized access to sensitive subscriber information. The leaked data contained personal details of millions of users across Argentina including contact information and internal account identifiers. This breach was later circulated on various underground hacking forums and data sharing platforms posing a risk of targeted phishing and social engineering attacks against the affected customers.
