Announcement

ΕΠΙΣΤΡΟΦΗ
20-Aug-2022, 06:00 PM

DESFA suffered a cyberattack on part of its IT infrastructure by cybercriminals that have tried to gain illegal access to electronic data, with a confirmed impact on the availability of some systems and possible leakage of a number of directories and files.

We have managed to ensure and continue the operation of the National Natural Gas System (NNGS) in a safe and reliable way. The management of the NNGS continues to operate smoothly and DESFA continues to supply natural gas to all entry and exit points of the country safely and adequately.

We are investigating the root causes of the attack, and we have mobilized several technical experts to help us on this matter, as well as on the recovery of the systems back to normal operations, as soon as possible. To protect our customers and partners we proactively deactivated most of our IT services and we are now gradually recovering our IT systems back to normal operation.

We have already informed all the relevant authorities and organizations and continue to work closely with the Ministry of Digital Governance, the Hellenic Data Protection Authority, the Cyber Crime Unit of the Hellenic Police, the Hellenic National Defence General Staff as well as with the Ministry for the Environment and Energy and the Regulatory Authority for Energy, to resolve this and minimize any possible impact.

DESFA remains firm in its position not to negotiate with cybercriminals.
