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.

Dutch telecommunications provider **Odido** disclosed a cyberattack in which threat actors gained unauthorized access to a **customer contact/CRM system** and **downloaded personal data** associated with approximately **6.2 million customer accounts**. Odido stated the intrusion was detected over the **February 7–8** weekend and that access was terminated as quickly as possible; the company also reported the incident to the Dutch Data Protection Authority (**Autoriteit Persoonsgegevens**) and engaged external cybersecurity experts to support investigation and additional defensive measures. Odido said its **telecom operations were not disrupted**, and no threat actor group has publicly claimed responsibility; reporting also notes the attackers allegedly contacted Odido to assert they had stolen millions of records. Exposed data varies by customer but may include **full name, address/place of residence, mobile number, customer number, email address, IBAN bank account number, date of birth, and identification document details** (e.g., passport/driver’s license number and validity). Odido emphasized that **passwords** (including for the *My Odido* portal), **call logs**, **location data**, **invoice/billing details**, and **scans of ID documents** were **not** affected. Odido is notifying impacted individuals via email from **`info@mail.odido.nl`** or by SMS, and warned that the stolen data could be used for **impersonation and phishing** attempts that appear to come from Odido.

Dutch telecom **Odido** reported that attackers stole data on **6.2 million** current and former customers, while the threat actor claimed the dataset covers **8+ million** people and demanded **€1M+** in ransom, threatening to publish data in daily tranches if unpaid. Reporting indicates the company refused to pay, and the extortionists proceeded with a staged leak strategy intended to maximize public and media impact. Subsequent leak batches reportedly included not only typical customer identifiers (e.g., names, addresses, phone numbers, dates of birth, bank account numbers, and ID numbers) but also **internal customer-service notes** containing highly sensitive context such as stalking, threats, domestic violence, and protected addresses—creating potential **physical safety risks** for affected individuals. The leak cadence was described as multiple dumps over consecutive days (including a “final dump”), drawing significant national attention in the Netherlands and increasing the likelihood of intensified law-enforcement focus on the perpetrators.

**ShinyHunters** has claimed responsibility for breaching Dutch telecommunications provider **Odido** (and brand **BEN**) and stealing a much larger dataset than the company initially indicated. Odido previously disclosed that attackers accessed its customer contact system and downloaded customer data, reporting the incident to the Dutch Data Protection Authority, cutting off attacker access, and bringing in external incident-response support. Odido said the exposed data varied by customer and could include identifiers and contact details such as name, address, mobile number, customer number, email address, **IBAN**, date of birth, and some ID details (e.g., passport/driver’s license numbers and validity), while stating that Mijn Odido passwords, call/location/data/billing details, and scans of identity documents were not exposed. ShinyHunters subsequently listed Odido on its leak site and alleged theft of **~21 million records** tied to **~8 million customers**, asserting Odido downplayed the scope. The gang’s claims also include highly sensitive elements—most notably **plaintext passwords**—and additional materials such as internal corporate documents and source code, which (if accurate) would materially increase risks of credential stuffing/account takeover, identity fraud, and follow-on intrusion. At the time of reporting, the expanded dataset details (including plaintext passwords and source code) were presented as **attacker claims** rather than independently confirmed by Odido.
