CoinStats responded immediately to the situation.

Besides the security issue, some iOS and Android users received fraudulent notifications claiming they had won a 14.2 ETH prize. These notifications directed users to log into a fake CoinStats AirScout wallet via a fraudulent website. Worryingly, these scams were distributed through push notifications and in-app messages.
Complications for CoinStats
The CoinStats team, led by CEO Narek Gevorgyan, is working hard to investigate the extent of the attack and its underlying causes. At the same time, they are implementing security measures to restore the production environment and reactivate the app as soon as possible. During this period, users have been urged to stay alert for potential scammers who might exploit the situation to offer false help.
The breach has raised concerns about possible vulnerabilities in the wallet generation process and the storage of private keys on the company’s servers. It is speculated that the attackers may have discovered patterns in the randomness of the wallet generation process, allowing them to predict private keys and compromise user funds. Although no connected wallets or API connections have been reported as affected, some users have claimed that other wallets linked to DeFi features were drained. However, these claims have not yet been confirmed.
CoinStats has assured users that connected wallets, which only require read-only access, remain safe under any conditions. Despite the issues, the company remains committed to strengthening security and restoring user trust.
