The Department of Cadastre and Land Surveying (TKX) informs that after a thorough evaluation of all data, with the contribution of all stakeholders, it has been confirmed that the technical problem that occurred in the "Cadastre Portal", on Wednesday, 8 April 2023, arose after a "Cyber attack".
It is clarified that since last Wednesday, where the technical problem was detected, the relevant crisis response protocol, which is provided for such cases, was immediately activated, with the notification and involvement of the Digital Security Authority (DSA) and the Sub-Directorate of Cybercrime (DEDO) of the Police Headquarters. Thus, the responsible technicians of the TKH and the Department of Information Technology Services (DIT), with the assistance of the support companies of the TKH's computer systems, immediately interrupted the operation of both the Land Registry Portal and the rest of the TKH network, in order to isolate the problem and begin the process of investigation and resolution.
The investigation of the problem is being carried out by all stakeholders, i.e., the TCX, the CPS, the OSS, the HSE, the companies supporting the relevant systems and others, with the aim of resolving the problem as soon as possible in a safe manner. Due to the criticality and size of the TCX systems, and the nature of the attack on them, there will be a phased restoration of the systems, starting with the restoration of the basic operations of the District Land Offices. Subsequently, the gradual restoration of the Land Registry Portal operations and its connection to the external users of the system is planned. From the analysis carried out, it appears that there has been no leakage of TCX data and the problem is limited only to the Land Registry Portal.
The TCX again apologizes for any inconvenience suffered by citizens and will inform the public and directly the affected persons with announcements in case scheduled appointments need to be postponed. At the same time, both the Ministry of Interior and the TKH express their sincere thanks to those persons and agencies who have been working tirelessly since Wednesday to resolve the problem.
