Swissport took to Twitter on Friday to announce that its IT infrastructure had been attacked by ransomware and apologize for any effect on service delivery.

The company stated that the attack had been contained, and they were working to resolve the issue. The security teams quickly spotted the attack and started restoring the firm’s IT systems.

The attack on two German oil suppliers forced energy giant shell to reroute oil supplies to other depots. Although, it is not clear if the attacks are linked or coordinated

The company did not disclose details about the attack. The company could not share any information on the type of ransomware used or whether the attackers had managed to steal any data. Also, no ransomware group has claimed the attack on the dark web. Some systems were shut temporarily while most critical systems and applications remained unaffected.
