Dutch police believe local hackers were involved in the cyberattack that compromised the personal information of millions of customers at telecommunications provider Odido earlier this year.
Investigators have found strong evidence linking Dutch-speaking suspects to the February breach. One of the key findings is a phone call made to Odido’s customer service shortly before the attack, during which a Dutch-speaking man allegedly posed as an IT employee. Police say the company was deceived through a phishing scheme that ultimately allowed attackers to gain access to internal systems and steal customer data.
The Dutch National Police said the investigation uncovered multiple digital traces that point to domestic hackers. Officials explained that cybercrime investigations often take time, but attackers frequently leave behind evidence that can help identify those responsible. Investigators said they secured several important traces throughout the case and continue working to identify and prosecute everyone involved.
The breach affected approximately 6.2 million Odido customers after attackers gained access to the company’s customer service platform. The stolen information included names, addresses, email addresses, phone numbers, bank account details, and, in some cases, identification numbers. The ShinyHunters extortion group previously claimed responsibility for the attack and later published a large archive containing the stolen data after ransom demands were not met.
Authorities have not yet announced any arrests, but the investigation remains active as police continue to gather evidence and track those believed to have participated in one of the largest data breaches in Dutch history.
