Understanding Vulnerability Propagation in the Cargo Ecosystem

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.

How the 120k ETH was recovered from the exploiter of Wormhole attacker

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…

A Powerful Formal Verification Engine for Solidity Smart Contracts

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.
