The Cactus ransomware group claims to have hacked Coop, one of the largest retail and grocery providers in Sweden.

Coop is one of the largest retail and grocery providers in Sweden, with approximately 800 stores across the country. The stores are co-owned by 3.5 million members in 29 consumer associations.

The Cactus ransomware group claims to have hacked Coop and is threatening to disclose a huge amount of personal information, over 21 thousand directories.

Coop doesn’t use Kesaya software, anyway, it was impacted by the incident because one of their software providers does.

According to BleepingComputer, the impacted provider was the Swedish MSP Visma who manages the payment systems for the supermarket chain.

Visma confirmed they were affected by the Kaseya cyber attack that allowed the REvil ransomware to encrypt their customers’ systems.

The Cactus ransomware operation has been active since March 2023, despite the threat actors use a double-extortion model, their data leak site has yet to be discovered.

Kroll researchers reported that the ransomware strain outstands for the use of encryption to protect the ransomware binary.

Cactus ransomware uses the SoftPerfect Network Scanner (netscan) to look for other targets on the network along with PowerShell commands to enumerate endpoints. The ransomware identifies user accounts by viewing successful logins in Windows Event Viewer, it also uses a modified variant of the open-source PSnmap Tool.
