Executive Summary
AI-generated
On September 4, 2026, a class action lawsuit was filed against Ledger, alleging that the company failed to adequately protect customers' personal information and did not take sufficient measures following previous incidents. The plaintiff claims he lost nearly $2 million in cryptocurrency due to attackers using information obtained from incidents in 2020 and 2023 to specifically target his crypto assets. The complaint alleges a "systematic" disregard for the security and privacy of customers' data, with Ledger downplaying the impact of the incidents and failing to promptly inform users about the risks.
