INDOTEL investigates Claro data exposure affecting mobile customers
Santo Domingo.- The Dominican Telecommunications Institute (INDOTEL) is monitoring an unauthorized data exposure reported by Claro Dominicana, involving a group of individual mobile service customers.
The telecommunications regulator said it is coordinating with the National Cybersecurity Center (CNCS) and other competent authorities as investigations continue to determine what happened, establish the scope of the incident and identify those responsible.
According to information provided by Claro, the data exposed includes mobile phone numbers, national identity card numbers and the type of service contracted. INDOTEL stressed that these details correspond to the information reported by the telecommunications provider and are currently being verified as part of the authorities’ investigations.
What Claro has said about the incident
Claro Dominicana confirmed that it detected an unauthorized exposure involving information from a group of customers with individual mobile services.
The company said its specialized security team activated established protocols after becoming aware of the incident and began verification procedures to determine the extent of the exposure and identify the information involved.
Claro stated that the exposed information does not, by itself, allow access to customers’ accounts, the execution of transactions or access to the content of their communications.
The company has not publicly specified how many customers were affected or provided details about the circumstances or origin of the incident. It said it would continue strengthening its security processes and urged customers to follow its general recommendations for protecting their information.
INDOTEL monitoring the response
INDOTEL said its monitoring efforts include verifying the extent of the exposure, the measures adopted by Claro to contain the incident and prevent additional impacts, and the information and guidance being provided to affected customers.
The regulator also emphasized the importance of preserving evidence and ensuring that the competent authorities have timely access to the information required for their investigations.
Because exposed personal information could potentially be used in fraudulent schemes or identity-theft attempts, INDOTEL urged customers to remain alert to suspicious calls, text messages and other communications.
Users are advised not to share passwords, verification codes or banking information, even if the person contacting them appears to know personal details. INDOTEL also recommended verifying requests through official channels and reporting suspicious activity to the telecommunications provider or the appropriate authorities.
The regulator further urged the public not to download, share or disseminate files containing personal information allegedly connected to the incident, particularly while the investigation into the exposure remains ongoing.
For now, the investigation remains focused on establishing the precise scope of the incident and determining what information was actually exposed. INDOTEL’s clarification that the data reported by Claro is still being verified is important, as additional claims circulating online about the breach have not been independently confirmed by the company or authorities.
