Decentralized Finance industry 53-hour chase for the culprit: $25 million in assets completely recovered after being stolen.

The DeFi field has recently experienced a thrilling event that lasted for 53 hours.

Fortunately, the attacker's methods were not sophisticated this time. On the second day after the assets were stolen, the security team successfully created a profile of the attacker based on the clues left before and after the attack. They then collaborated with various parties at home and abroad, cross-referencing information and making breakthrough progress, gradually closing in on the attacker. By the third day, under immense pressure, the attacker took the initiative to communicate with the victim and began to return some of the assets. After further negotiations, all the stolen assets were ultimately recovered.

Although this crisis has ultimately been resolved, industry practitioners should engage in a deep reflection and discussion about the future development of Decentralized Finance amidst their brief sense of relief.

53-Hour Nightmare in the DeFi Field

To help readers who are not familiar with this event better understand the situation, let's review the process of this attack incident.

On April 18 and 19, there were two incidents of smart contracts being attacked in the DeFi sector, with total losses amounting to 25.46 million USD. The first attack targeted a decentralized trading platform, resulting in a loss of 217,000 USD. Due to the relatively small amount, it did not attract widespread attention. However, just 24 hours later, another lending platform, Lendf.Me, also fell victim to a similar attack, incurring losses of up to 25.24 million USD, almost draining the platform's liquidity pool, leaving only 6 USD in assets.

Interestingly, amid the chaos, some victims pleaded with the attackers to return their assets through the messaging feature on the blockchain.
