In a world where blockchain hacks and capital exploitation seem to occur almost weekly, the question arises: Can we effectively prevent these security breaches?
BlockSec, the expert in the blockchain security field, offers valuable insights. We acknowledge the complexity of the issue while actively working to enhance security measures. Phalcon Block, one of our products, provides precise alerts before attack transactions are executed, and takes automatic actions to fight hackers back.
Here's our BlockSec founder, Professor Yajin Zhou, sharing his perspectives on the proactive approach to blockchain security during a monitoring panel.
In the world of blockchain security, the answer is a bit complex. Our team is constantly working on ways to spot DeFi hacks. If you ask us whether we can catch all ongoing attacks, the answer is yes. However, here's the catch: if we label every transaction as suspicious or an attack, we can find all hacks, but this creates a problem. We need to carefully balance between false alarms and missing real threats.
When we create products for our customers and set up monitoring systems, we have to make sure our alerts make sense. If our system generates too many alerts, like 50, 100, or even 200 a day, most users will ignore them because most of them turn out to be false alarms. So, our challenge is to maintain that balance effectively.
At Blocksec, we're actively working on strategies to spot attacks while reducing false alarms. Looking ahead, with the help of the security community, we hope to identify a large portion of attacks. While we might not prevent them all, we can certainly improve our detection abilities significantly.
In the world of Web3 security, a few things stand out that can make Web3 more vulnerable to attacks compared to Web2.
So, all of these factors together make Web3 a tempting target for attackers but a tough place for protocols to stay secure.
I have encountered challenges related to audio debases and privacy transactions within Blocksec. Similar to flashbots, these services are susceptible to abuse by attackers. One proposed solution from a colleague suggests investing transactions within flashloans to prevent their misuse. However, I believe this solution may not be practical or accessible in a decentralized world.
Preventing the abuse of such services by attackers remains an open question. Nevertheless, there are a few actions we can take.
While these measures may not fully resolve the issue, they can help address the current challenges we face.
When it comes to recommendations, I believe exploring the DeFi Hack Labs is an excellent starting point for transitioning from web2 to web3 security.
This resource offers a wealth of past hack transactions that can be analyzed to gain insights into the motives and methods behind these attacks. By understanding the underlying causes and triggers of these hacks, one can develop tools to analyze and detect similar attacks in the web3 ecosystem. Consider utilizing both static and dynamic analysis tools, which can be developed independently or by building upon existing solutions. Continuously improving and expanding your knowledge in this area will be crucial.
In our experience with front-running attack transactions, the process involves setting up infrastructure to monitor the memory pool transactions.
A crucial aspect is developing an automated system that can swiftly synthesize front-running transactions. This involves replicating the attack behaviors from the malicious contracts within your own smart contracts. It becomes essential to replace critical variables, such as substituting the attack address with your own black hat addresses. Additionally, having a responsive infrastructure is crucial to ensure immediate execution as soon as your transaction is on the blockchain.
In conclusion, BlockSec's expertise in the realm of blockchain security reflects our commitment to addressing the evolving challenges of Web3. BlockSec's approach combines technological innovation with collaboration and community involvement, ensuring a safer blockchain ecosystem for all users.
