Two recent major cyberattacks in Turkey resulted in the compromise of the data of nearly half a million people and caused colossal reputational and financial damage.

The KVKK stated that the data of hundreds of thousands of Vodafone subscribers, employees, and partners may have been accessed on the darknet. According to the Turkish KVKK, the incident, which began on January 10, was only discovered more than two weeks later. During the investigation it was concluded that the personal data subject to the incident may have been obtained from the data processor's system. Information pertaining to approximately 320,000 individuals was put at risk:

• Names
• Contact details
• Data on services and devices.

In its statement, the company emphasized that the leaked dataset did not contain any ID numbers or financial data.

Following this, on January 22, a cyberattack completely paralyzed the digital services of the well-known restaurant chain Köfteci Yusuf. The breach occurred as a result of direct interference with a local SQL database that contained information from the online ordering system Yemekpos and payroll transactions. Data from more than 150,000 customers fell into the hands of the attackers: from food preferences to full names, addresses, and phone numbers. For the 13,000 employees, the consequences were more severe: their identity documents and internal HR information were compromised.

The Turkish Personal Data Protection Authority (KVKK) published information about the incident on January 27, noting that the investigation on the subject still continues. As a result, the restaurant chain could face fines amounting to millions of Turkish liras. This case has become one of the largest in Turkey's HoReCa sector.

Data-related incidents lead to negative, often severe outcomes for business: colossal reputational losses, customer outflow, legal risks, and multi-million fines. These incidents prove that in modern business, information security is not a technical line-item expense but a strategic investment in resilience, trust, and business continuity. Proactively building comprehensive protection and regularly auditing systems has become a necessary condition for survival in a market where the price of a single incident is measured in millions and years of reputation recovery.

Implementation of data protection systems is an inevitable part of building sustainable information security posture. To assist companies in ensuring reliable data protection, we developed Risk Monitor – comprehensive Next-Gen DLP platform for data protection and comprehensive business risk mitigation. The solution enables to deal with a broad set of tasks, ranging from detection of theft and document forgery to revealing cases of systematic idleness and regulatory non-compliance.
