Odido Under Fire: Recent Cyberattacks and Data Security Concerns
Dutch telecom provider Odido has been grappling with a series of cybersecurity incidents over the past several months, culminating in a significant data breach affecting millions of customers. These events have raised serious questions about the company’s security infrastructure and data protection practices.
Recent Outages and Disruptions
In June 2025, Odido experienced two separate mobile network outages across the Netherlands, impacting calling and data services. The cause of these disruptions was initially unknown, but services were restored within a few hours. Nltimes reported that the company did not suspect a cyberattack at the time.
Data Breach and Ransomware Demand
More recently, in February 2026, Odido was the target of a sophisticated social engineering attack. Hackers posed as IT department staff to gain access to sensitive customer data, including names, addresses, phone numbers, and bank account numbers. LinkedIn reports that approximately 6.2 million customers were affected.
A hacker group subsequently published data from 680,000 Odido customers on the dark web and demanded a ransom. Reddit discussions indicate that Odido has refused to pay the ransom.
Company Response and Customer Impact
Odido has engaged cybersecurity experts and reported the breach to the Dutch Data Protection Authority. While the company states that passwords, call records, and billing data were not compromised, customers have been advised to remain vigilant against potential phishing attempts and fraudulent activity.
Ongoing Concerns and Service Status
Customers continue to report service disruptions. Downdetector shows ongoing reports of issues with Odido services, though the nature of these issues is not always directly linked to the recent cyberattacks. The repeated incidents raise concerns about the overall stability and security of Odido’s network.
