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.

11 events from the most recent confirmed update back to the earliest known activity.
On March 26, the Dutch Data Protection Authority said it had opened a formal investigation into whether Odido kept customer personal data longer than legally necessary, after complaints from people who said their data was stolen despite no longer being customers. The authority and the Rijksinspectie Digitale Infrastructuur were also examining whether security around Odido’s customer systems had been adequate.
By March 25, the Dutch CJIB and fraud-reporting organizations were handling a surge of reports about fake traffic-fine emails demanding payment within 24 hours. Authorities and researchers said a connection to the Odido breach was plausible because the leaked personal data could be used to make the phishing messages more convincing.
On March 1, ShinyHunters released what it described as the full Odido customer dataset for free online, culminating a series of four leak-site releases. Reporting said the final dump brought the exposed total to about 6.1 million unique email addresses and was characterized as one of the largest data leaks in the Netherlands.
As the leaks escalated, Odido CEO Søren Abildgaard said the company would not negotiate with the extortionists, in line with Dutch police guidance against ransom payments. Odido also offered affected customers a free 24-month digital security package and warned them to watch for phishing and fraud.
The Odido breach was added to Have I Been Pwned on February 26, making the exposed dataset searchable for affected users. Reporting said the breach involved approximately 688,100 customer accounts in the initial HIBP entry.
After Odido refused to negotiate, ShinyHunters started a staged leak campaign, publishing about 1 million records on February 26 and another roughly 1 million early the next day. The leaked data reportedly included names, addresses, emails, phone numbers, IBANs, and identity document numbers.
After ShinyHunters' public claim, Odido confirmed the cyberattack but rejected assertions that plaintext passwords, social security numbers, billing data, call details, location data, or scans of identity documents were exposed. The company maintained the breach was limited to data in the customer contact system and that core telecom services were unaffected.
By February 24, ShinyHunters added Odido to its dark web leak site, claimed responsibility for the intrusion, and threatened to leak stolen data unless the company paid more than €1 million. The group alleged it stole roughly 21 million records tied to about 8 million customers, including sensitive personal, financial, and internal corporate data.
On February 12, Odido publicly disclosed the breach, said 6.2 million current and former customers were affected, and published an incident update and FAQ. The company also reported the incident to the Dutch Data Protection Authority and began notifying impacted customers by email or SMS.
During the intrusion, attackers accessed and downloaded customer personal data from Odido's contact system. Odido later said the exposed data could include contact details, IBANs, dates of birth, and some identity document details, but not passwords, call records, billing data, or ID scans.
Odido detected unusual activity and unauthorized access to its customer contact management system over the weekend of February 7–8, 2026. The company says it terminated the access quickly and began incident response measures.

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.

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.
