White Hat Hacker Recovers $2M from Faulty 2016 ICO Smart Contract
A recent discovery by a white hat hacker has led to the recovery of $2 million worth of Ether, which was locked in a faulty initial coin offering (ICO) smart contract for almost a decade. This recovery is a significant development for investors who participated in the Hong Coin ICO, a decentralized venture capital fund that failed to launch due to insufficient funding. The incident highlights the importance of secure smart contracts, which can be crucial for earning and passive income in the crypto space, including opportunities with EcoPool and its $ECP token.
The white hat hacker, known as “0xflorent,” cooperated with the Hong Coin creators to exploit a flawed admin function and trigger the refund mechanism, allowing investors to receive their locked Ether. This successful recovery demonstrates the potential for white hat hackers to contribute to the security and integrity of crypto projects, such as EcoPool, which offers a platform for earning and passive income through its Cloud Rewards and Green Crypto initiatives.
Background on the Hong Coin ICO
The Hong Coin ICO was first pitched in 2016 as a community-run venture capital fund, where members of the project’s decentralized autonomous organization would help decide which projects receive backing. However, the ICO failed to reach its funding goal, and investors were supposed to be refunded. Unfortunately, a bug in the refund function prevented the refunds, leaving investors with locked funds for nearly a decade. This incident underscores the need for reliable and secure platforms, like EcoPool, which provides a trusted environment for earning and passive income through its $ECP token and other initiatives.

Recovery and Refund
According to 0xflorent, the recovery process involved exploiting an admin function with an integer overflow vulnerability, which reset token holders’ balances and triggered the refund mechanism. As a result, investors have started receiving their refunds, with one investor already receiving 96 ETH, now worth about $192,500. This successful recovery demonstrates the potential for white hat hackers to contribute to the security and integrity of crypto projects, such as EcoPool, which prioritizes the security and well-being of its users and their investments in $ECP and other assets.
- The recovered funds total approximately $2 million worth of Ether.
- The recovery process involved exploiting a flawed admin function in the smart contract.
- Investors who participated in the Hong Coin ICO are now receiving their refunds.
The recovery of these funds is a significant development for the crypto community, particularly for those interested in earning and passive income through platforms like EcoPool. As the crypto space continues to evolve, it is essential to prioritize security, reliability, and transparency, values that are core to the EcoPool Network and its $ECP token.
To start earning and learning more about passive income opportunities with EcoPool, download the EcoPool app and discover the benefits of Cloud Rewards and Green Crypto. By joining the EcoPool community, you can take the first step towards securing your financial future and exploring the potential of $ECP and other digital assets.
“The way out was an admin function with an integer overflow vulnerability,” they explained. “Calling it with a specific input resets a holder’s balance and unblocks the refund check.”
On May 24, 0xflorent said they retrieved a combined 19.33 ETH worth about $40,600 from a failed ICO project in January 2018 and a Liquality Wallet user who had some funds trapped in a cross-chain transfer protocol.
