Updates and insights
BlockSec's latest study on transaction-based phishing on Ethereum has been accepted for full paper publication at ACM CCS!
In this article, we explore the vulnerabilities that arise during hook interaction logic, specifically concentrating on two scenarios: flawed access control and improper input validation.
Phalcon Block will revolutionize the fight against hackers in the Web3 world.
BlockSec and Cobo have collaborated to develop a solution that assists LPs in withdrawing funds before the protocol pauses and the liquidity pool freezes.
This is the first article of our series exploring security risks in Uniswap v4’s hook mechanism! In this article, we provide a comprehensive overview and foundational understanding for our readers.
In the ever-evolving world of Web3, the significance of security cannot be overstated. Despite bear market conditions, the alarming surge in DeFi hacks and scams has raised concerns.
In a world where blockchain hacks and capital exploitation seem to occur almost weekly, the question arises: Can we effectively prevent these security breaches?
L1/L2 competition is becoming increasingly fierce. According to DefiLlama, there are currently over 200 chains, with 120 of them being EVM chains, including star projects like Arbitrum, Optimism, and Base.
In this article, we will show how to build and deploy Uniswap V2 contracts, including the uniswap-v2-core and uniswap-v2-periphery, into Phalcon Fork.
Phalcon Fork is a specialized tool designed for Web3 developers and security researchers to conduct collaborative testing with private mainnet states.
We were thrilled to receive so much positive feedback and engagement from both longtime users and new followers after launching our 7 Days of Phalcon journey on Twitter.
Phalcon supports the debugging of a transaction, a powerful feature that can significantly improve the analysis efficiency for complex transactions.
EVM (Ethereum Virtual Machine) compatible blockchains are designed to be compatible with the Ethereum blockchain’s smart contract functionality, programming language (Solidity), and tooling ecosystem.
On 2023–03–17 05:48:59 (UTC), BlockSec successfully blocked an attack attempt on ParaSpace (a top NFT lending protocol) and protected crypto assets worth $5M.
In the past three years, we have observed several security incidents in the DeFi ecosystem. To defend the threats, code-centric methods, e.g., static code auditing, smart contract scanning tool, or dynamic fuzzing, are adopted by the community.
Phalcon is a powerful transaction explorer designed for DeFi community. It provides comprehensive data on invocation flow, balance changes, and fund flows for transactions. It also supports transaction simulation.
In the past two years, we have observed a couple of security incidents in the DeFi ecosystem. Not surprisingly, there exist several cases of attacked contracts that have been audited by multiple companies.
