A cyber attack was carried out on the company carrying out the Brenner Tunnel project between Austria and Italy

Austria's Tiroler Tageszeitung newspaper published the company's confirmation of the attack in mid-October.

BBT SE Spokesperson Julia Gruber stated in her statement that the attackers accessed some of the data accessible over the internet.

After the attack was detected, the company activated security procedures, isolated the affected systems, assigned external cyber security experts for examination and informed the authorities.

In a statement quoted by Austrian public broadcaster ORF, the company stated that, according to current findings, work processes in the tunnel construction were not affected by the attack.

It is being investigated which data the attackers accessed and to what extent they infiltrated the company's systems.

On the other hand, it was noted that the Austrian State Security and Intelligence Unit (DSN) was in contact with the Austrian Federal Railways (ÖBB) regarding the incident.

It was claimed that the "Everest" group claimed responsibility for the attack

Cyber security monitoring organization DeXpose reported in the recording published on October 17 that the group called "Everest" claimed responsibility for the attack and threatened to publish the data if the ransom demand was not met.

While there was no official confirmation that the group carried out the attack, BBT SE left unanswered questions about whether the attackers were interviewed and whether payment was made.

BBT SE announced on October 20 that the Brenner Tunnel is planned to be put into service in 2034 and the total cost of the project is expected to reach 11.7 billion euros.
