The US SEC provides over $104 million in rewards to 7 whistleblowers

The US Securities and Exchange Commission (SEC) announced on its official website that it has provided over $104 million in rewards to 7 whistleblowers whose information and assistance have contributed to the success of SEC enforcement actions and related actions by another agency. This amount ranks fourth in the history of the SEC Whistleblower Program. It is reported that the 7 whistleblowers consist of two groups of joint whistleblowers and three individual whistleblowers, and the information provided by each group of whistleblowers has either prompted the SEC to initiate an investigation or played a significant role in the SEC’s investigation. The assistance provided by these 7 individuals to the staff includes providing documents that help law enforcement agencies substantiate allegations of misconduct, participating in interviews, and identifying potential witnesses.

Curve Finance hackers have returned all the funds to Alchemix in the Curve pool.

DeFi lending protocol Alchemix tweeted that Curve Finance hackers have returned all the funds to Alchemix in the Curve pool and a full report will be released later.

Earlier, the Curve Finance hackers stated in the transaction memo for returning funds to Alchemix Finance: “I’ve seen some ridiculous views, so I want to clarify that I’m returning the funds not because you can find me, but because I don’t want to ruin your project. Maybe this is a lot of money for many people, but not for me, I’m smarter than all of you.”

Ethereum compiler Vyper releases vulnerability incident analysis report, the vulnerability has been fixed and tested in v0.3.1.

Ethereum compiler Vyper has released an analysis report on the vulnerability incident last week: on July 30th, multiple Curve liquidity pools were exploited due to a potential vulnerability in the Vyper compiler. Although the error has been identified and patched, the impact on protocols using the vulnerable compiler was not recognized at the time and they were not explicitly notified. The vulnerability itself was an improperly implemented reentrancy protection, and the affected Vyper versions are v0.2.15, v0.2.16, and v0.3.0.

The vulnerability has been fixed and tested in v0.3.1, and v0.3.1 and higher versions are secure. Measures will be taken in the future to improve the correctness of smart contracts compiled with Vyper. Firstly, improve the testing of the compiler, including continuing to improve coverage, comparing the compiler output with the language specification, and using formal verification (FV) tools to verify the compiler bytecode. Secondly, provide developers with tools to test their code more easily using multiple approaches, including source code and bytecode level testing. Thirdly, strengthen stricter two-way feedback for using the Vyper protocol.
