Athens, Greece – The Hellenic Cadastre, Greece’s national property registry, was targeted in a cyberattack, raising concerns about potential data breaches. While authorities claim no data was deleted, the full extent of the attack remains unclear.
The attack, originating from two different locations, saw hackers exploit compromised employee passwords. Officials at the Ministry of Digital Governance confirmed the initial attack resulted in the theft of insignificant files. However, a subsequent breach on Thursday afternoon targeted a server containing a backup of the main property registry database, raising serious concerns.
Immediate action was taken, with Hellenic Cadastre employees instructed to change passwords and implement two-factor authentication. By late Thursday night, while data deletion was ruled out, the possibility of data copying and the presence of dormant malware remain key concerns.
With over 1,500 computer and server terminals requiring investigation, determining the full impact of the attack will be a lengthy process. The Joint Chiefs of Staff’s Cyberdefense Division is actively investigating the incident, with a comprehensive report expected in the coming days.
Despite the attack, property transactions remain unaffected, and all regional offices of the Hellenic Cadastre continued operations without disruption on Thursday.
