The group action related to the Chesterton’s data breach is now closed and is no longer being pursued by KP Law.
We are no longer accepting new claims for this matter.
On 11 January 2023, CSL detected a serious cyber incident. The exact timing of the breach remains unclear. However, based on information available, we understand that the ransomware group responsible for the attack created a website to display sample data, which reportedly went live on 9 January 2023.
Cybersecurity experts have indicated that the timestamp associated with the breached data is 30 November 2022. These experts suggest that the breach likely occurred between 30 November 2022 and 9 January 2023. It has also been noted by experts that such groups typically act swiftly once a target is identified. Accordingly, it is believed that the initial penetration into the system was likely no more than four weeks prior to the data timestamp.
Following review, KP Law is no longer pursuing this claim. As a result, no further claims in connection with the breach can be accepted.
