The groups NoName057(16) and Z-Pentest claimed responsibility for the cyberattacks that caused disruptions in refrigeration systems at European supermarkets, according to information released by the specialized press.

The claims were published on Telegram channels, accompanied by alleged data belonging to the systems of a refrigeration technology supplier.

However, cybersecurity experts question the authenticity of the statements, as there is no independent confirmation that the groups are actually responsible for the incidents.

Remotely operated refrigeration systems

The attacks are believed to have allowed for the remote alteration of operating parameters in certain refrigeration equipment, causing temperature increases in display cases and cold storage rooms used for food preservation.

In some European establishments, temperatures have reached levels incompatible with the preservation of fresh and frozen products, forcing the removal or destruction of goods.

The incident affected various European operators and highlighted the risks associated with remote access to industrial control systems.

In Portugal, the Mosqueteiros Group previously confirmed disruptions at seven Intermarché stores, three of which resulted in losses of food products.

Responsibility remains to be determined.

The available information does not allow for a conclusive attribution of responsibility for the attacks to Russia, the Russian state, or the groups that claimed responsibility for the incidents.

It is also not possible to establish, based solely on public information, that all affected supermarkets were victims of the same technical intrusion.

The investigation should clarify the points of entry, the use of credentials, and the responsibilities of the different parties involved.

For retailers, the main consequence is the need to strengthen the security mechanisms of connected equipment, especially when a computer disruption can directly compromise food safety and cause merchandise losses.
