$UN on BSC was attacked by the flash loan with a loss of $26,000
We evaluate and compare seven free or open-source Static Application Security Testing (SAST) tools for Java. The post highlights the importance of SAST tools in detecting security vulnerabilities in software development and provides insights into improving the detection capabilities of these tools.
The study analyzed 20,000 Rust packages and their dependencies to understand vulnerability propagation in the Cargo package ecosystem. Accurately calculating affected versions reduces false positives, and version ranges are not always reliable indicators. Challenges faced include a lack of security awareness and incentives for package maintainers. The study recommends improving package review mechanisms, providing incentives for security, and implementing security governance strategies to reduce the risk of software supply chain attacks.
OpenAI announced on March 24th that a weakness in the Redis client open-source library, redis-py, was responsible for the data breach. In addition to performing a thorough security assessment of smart contract code, MetaScan's Open Source Analyzer is specifically designed to pinpoint vulnerabilities in the open source software components utilized in the project.
On March 21, 2023, at 01:39:47 PM +UTC, the attacker(0xb189943) created and manipulated many new contracts, which gained ASKACR tokens from the ASKACR contract itself. Finally, the attacker gained 28,633 BSC-USD from the attack.
On February 2, 2022, at 18:24:13 UTC, a mysterious attacker launched an attack on the Wormhole cross-chain bridge on the Solana blockchain. Ultimately, the attacker successfully obtained 120,000 WETH from the Solana chain and transferred it to Ethereum through the cross-chain bridge. Without going into the specifics, we know that the attacker has successfully transferred the acquired WETH to their address on Ethereum. Afterward, the attacker disappeared and left behind this shocking event…
Smart Contracts are computer programs that enable decentralized applications on the blockchain. They are usually written in Turing-complete programming languages like Solidity, which is similar to JavaScript. In Solidity, a contract is a first-class object that can extend its capabilities by inheriting other contracts or delegating tasks to them. However, the complexity of this composability also makes smart contracts vulnerable to many security threats.
On February 28, 2023, MetaTrust’s on-chain monitoring engine discovered a serious security vulnerability in the recently open-sourced Zombier smart contract on the Ethereum blockchain. The contract has a reentrancy attack vulnerability and several parameter verification vulnerabilities, among other issues. If the client continues to use this contract, it may face significant security risks. For details, please see the vulnerability cause analysis report.
This post discusses the security challenges in the Web3 era and how the DevSecOps approach can be adopted to improve the security of the Web3 ecosystem. It emphasizes the importance of incorporating security analysis into the development process and introduces MetaTrust's tools and services for secure software development, including the world's first secure package manager for secure open-source development, an automatic security auditing tool for smart contracts, 24/7 runtime security monitoring, and a comprehensive security and risk score. By using these tools, developers can build a more secure and prosperous Web3 ecosystem.
On February 10, 2023, some reflection mechanism tokens on BNB Chain were attacked and spread to multiple tokens. MetaTrust conducted a thorough analysis and found several dozens of tokens that were not yet attacked through its exclusive IP Analyzer engine.
