Dutch Police Probe Local Role in Odido Breach Exposing 6 Million Customers

Dutch police said their investigation into the cyberattack on telecom provider Odido found indications that Dutch nationals may have helped carry out the breach, which exposed personal data belonging to more than 6 million customers. Investigators from Team High Tech Crime and the Public Prosecution Service said a Dutch-speaking man allegedly impersonated an Odido IT employee in a call to customer service shortly before the February intrusion, suggesting the attackers used social engineering and phishing to gain access.

Authorities said the attackers accessed a compromised customer contact system used by Odido, downloaded customer records, and later distributed the stolen data publicly. Police have already taken multiple servers linked to the hacker group offline and are appealing for information from the public and people in cybercrime circles, while warning that the investigation is expected to continue for several more months.
