There are many cases of exploits and hacks taking place in DeFi. In most of these instances, the DeFi protocol ends up suffering from massive losses or going under. However, Platypus took prompt action to regain control of their business and was able to recover a considerable amount of stolen funds.
The firm has reported that around $8.5 million of stolen funds are preserved in a contract where the hackers transferred them. Meanwhile, the remaining $380K was accidentally transferred to AAVE protocol while hackers were trying to capture it during a second hack attempt.
BlockSec is Using the Callback Option to Recover Funds
Yajin Zhou, the head of BlockSec, told the media that recovering $2 million in funds was part of the plan to reroute the remaining stolen cryptocurrencies under the control of hackers. He confirmed that the firm made use of Proof of Concept and ensured that $8 million siphoned goods were stranded on account of a lack of transfer function in hacker wallets.
The firm reported that hackers exploited the flash load calls back interface. BlockSec decided to invoke the Callback functions first before the hackers could take advantage. Therefore, the DeFi protocol was able to recover the USDC amount and withdraw them before hackers got a chance to upgrade their proxy for new implementation.
