Russian users of the Atomic Wallet crypto wallet, together with the DestraLegal legal service and PlainChain analysts, are preparing a class action lawsuit against a company that was previously seriously affected by a hacker attack.

Lawyers argue that Atomic Wallet did not take measures to prevent hacking, so users have the right to demand damages. The main reason for filing claims is “violation of the contractual obligation to ensure the safety of the property of the victims entrusted to Atomic Wallet.”

“Under the agreement, Atomic Wallet provides software for accounting for rights to virtual currency. Because Atomic Wallet did not adequately secure its software, users have lost the ability to own and manage their crypto assets,” the analysts said.

Users suffered large losses, the average amount of which was $20,000, DestraLegal specified. Analysts at Elliptic attribute the June incident to the North Korean Lazarus Group. Losses incurred by Atomic Wallet users amounted to more than $100 million.

Earlier, Atomic Wallet users from the United States filed a lawsuit against the platform and its head Konstantin Gladych. The victims claim that the platform’s behavior, which they describe as “careless and illegal,” has led to the compromise of numerous user wallets.
