Cyberattack Exposes Data of 21 Million Movistar Customers

A significant cyberattack has targeted Movistar, Spain's largest telecommunications company, resulting in the exposure of personal data belonging to 21 million Spanish customers. The threat actor, known only as 'Dedale,' claims responsibility and is offering the data for sale on the dark web. The compromised information includes names, national identification numbers (DNI), phone numbers, and service plans. A sample of one million records, all from former Peruvian Movistar customers, has been released to demonstrate the scale of the breach. Telefónica, Movistar's parent company, has confirmed the leak of the Peruvian data but is currently investigating the extent of the broader breach. "We are investigating this alleged security breach and will provide updates as they become available," a Telefónica spokesperson stated in an official press release. The incident highlights the ongoing vulnerability of large corporations to sophisticated cyberattacks and underscores the importance of robust data security measures. The incident serves as a stark reminder of the potential consequences of inadequate cybersecurity protocols for both individuals and corporations.
