Crypto Broker DeltaPrime Drained of Over $6M Amid Apparent Private Key Leak

As a seasoned analyst with years of experience in the cryptocurrency industry, this latest incident involving DeltaPrime is a stark reminder of the inherent risks that come with decentralized finance (DeFi) projects. The private key leak, resulting in over $6 million in tokens being drained, underscores the need for robust security measures in this rapidly evolving space.

Approximately $6 million in diverse digital tokens from the wallets linked to on-chain brokerage DeltaPrime were emptied out early on Monday, according to reports by security experts. This incident appears to be due to a potential private key breach.

The project is offered on both Arbitrum and Avalanche blockchains. Monday’s exploit impacted only the version on Arbitrum as of European morning hours – and users could not withdraw funds (on Arbitrum) due to how the utilization of borrowing and lending works on the platform.

A cybercriminal took over the administrative account for proxies with the address 0xx40e4ff9e018462ce71fa34abdfa27b8c5e2b1afb, and subsequently improved these proxies to direct traffic towards a harmful smart contract located at 0xD4CA224a176A59ed1a346FA86C3e921e01659E73. This was reported by Chaofan Shou, founder of Fuzzland, on platform X.

As a crypto investor, I understand that a Proxy is essentially a middleman or intermediary in our blockchain world. It communicates with users and other contracts, keeping its own logic to a minimum. This simple contract plays a crucial role in any application because any compromise it might face could potentially affect the entire protocol or system we’re relying on.

As a researcher, I can share that Cyvers, a security firm, alerted me through a Telegram message to CoinDesk about the discovery of exploits. They mentioned detecting “multiple unusual transactions” linked to Delta Prime and suggested that it appears the administrator might have lost access to their private key.

According to messages shared on Discord by members of the Delta Prime team, they are currently looking into an issue and working towards a solution. As of the morning in Europe, they have neither confirmed nor announced any exploit, keeping specific details under wraps.
