White Hat Hacker Unlocks $2 Million in 2016 Smart Contract

In a remarkable turn of events, a white hat hacker named Florent has successfully unlocked 1,003.62 ETH, valued at around $2 million, that had been trapped in the HongCoin project's ICO smart contract since 2016.

The funds were initially stuck due to a flaw in the refund mechanism after the ICO failed to meet its minimum target. The smart contract, launched on August 29, 2016, was unable to process refunds for 48 investors because of an error that prevented requests from being approved when balances exceeded a certain threshold.

Florent identified a vulnerability in the outdated Solidity v0.3.5 code which allowed for the unauthorized resetting of balances. By collaborating with the original development team, he facilitated the unlocking of these assets through a series of transactions.

So far, two of the investors have successfully withdrawn 96.5 ETH and have offered a reward to Florent for his efforts. Florent has a history of assisting in the recovery of funds from failed projects, utilizing his own software and AI tools to identify vulnerable contracts.

This incident comes at a time when the crypto sector has been grappling with a surge in hacks, with over $651 million lost in a single month earlier this year across various breaches.
