Greece's largest distributor of natural gas, National Natural Gas System Operator S.A. (or DEFSA), has stated that they've suffered a limited-scope data breach and IT system outage following a cyberattack. Further details were confirmed after their data was leaked by the Ragnar Locker ransomware gang.
In a public statement, DESFA — which has an annual revenue of €270 million — explained that attackers attempted to infiltrate its network but were largely thwarted by a quick response from their IT team. However, some files and data were accessed and possibly "leaked."
DESFA deactivated many of its online services to protect client data, though the company assures its consumers that this incident won't impact the gas supply, and that all input and output points will continue to operate at normal capacity. They have also declared that they will not be negotiating any ransom payments.
