Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: O’Brien Steel Service Co. experienced a cybersecurity incident between May 18, 2023, and June 1, 2023, resulting in the potential compromise of customers' personal information.

The incident exposed customers to risks such as identity theft, fraud, and financial losses, with documented cases of extraordinary harm (e.g., unreimbursed losses directly tied to the breach). The settlement fund covers legal fees, administrative costs, and payouts to victims, with claims accepted until December 29, 2025.
