Ragnar Locker ransomware gang hits Greek natural gas supplier DESFA

Greece’s largest natural gas distributor DESFA confirmed on Saturday that they suffered a limited scope data breach and IT system outage following a cyberattack.

In a public statement shared with local news outlets on Saturday, DESFA explained that hackers attempted to infiltrate its network but were thwarted by the quick response of its IT team.

However, some files and data were accessed and possibly “leaked,” so there was a network intrusion, even if limited.

DESFA cyberattack saw data leaked

DESFA said the perpetrators of the attack broke into its systems to gain access to files, and that the incident had had a “confirmed impact on the availability of certain systems”, with some data having been leaked.

It said that it had disabled “most of its IT systems” as part of efforts to contain the breach, but that supply of natural gas had not been affected.

“We have mobilised teams of technical and specialist experts to assist us in this matter and to get the systems back up and running as soon as possible,” the DESFA statement said.

The company is working with Greece’s digital ministry, its data protection office and local police to try and get to the bottom of the breach.

Ragnar Locker says it has found multiple flaws in DESFA’s systems, and that it has informed the company of these.
