Our investigation on meme coin SHAR Pump and Dump on #Solana

https://metasleuth.io/blog/pump-dump-shar-MetaSleuth

We have released our dataset on Web3 phishing website detection, containing 26,333 phishing URLs. Feel free to use the dataset for further research and development of better anti-phishing solutions.

.@OnyxDAO was attacked, resulting in a loss of nearly $4M. The root cause was unverified user input during the liquidation process. Specifically, key parameters of the liquidateWithSingleRepay function in the NFTLiquidation contract were controllable by the attacker, allowing manipulation of the extraRepayAmount variable through the repayAmount parameter. By exploiting this, the attacker was able to liquidate all collateral with just one token.

The key attack steps are summarized as follows:
1. The attacker first deposited oETH and borrowed various assets to reach the liquidation threshold. Simultaneously, they created a new contract that, through a donation attack and precision loss (inherent from the Compound V2 fork), reduced the oETH exchange rate, making the attacker's position eligible for liquidation.
2. The attacker then performed the liquidation. Due to insufficient parameter validation, the attacker manipulated the extraRepayAmount variable, which was added to the calculation of how many tokens needed to be liquidated. This allowed the attacker to obtain more oETH through liquidation, leading to a profit.

Attack Tx:

Address poisoning is on BTC now. The following is one concrete case. The phishing address (address 1) is disguising address 2 to send a small amount of BTC to address 3. Since addresses 2 and 3 have historic transactions, the attacker hopes to trick the owner into copying the wrong address.

BlockSec helps digital Hong Kong dollar to gain new momentum

As the Hong Kong government's support for the crypto industry continues to increase, major institutions are committed to providing innovative solutions, actively promoting the development of digital Hong Kong dollars, and helping Hong Kong become a global Web3 center.

In 2024, JD Group's JD Coin Chain Technology (Hong Kong), Yuanbi Innovation Technology, and the five companies that jointly applied for Standard Chartered Bank (Hong Kong), Animoca Brands, and Hong Kong Telecom (HKT) will be the first entities to issue stablecoins under the HKMA's sandbox framework, and conduct multiple use case tests on their respective proprietary Hong Kong dollar stablecoins.

Taking this opportunity, BlockSec, as a company with both a strong blockchain security industry and top security academic background, looks forward to contributing to the overall improvement of Hong Kong's Web3 ecosystem. Help Hong Kong become the first region in the world to allow banks to issue stablecoins, help enterprises and users enter the cryptocurrency market more safely, and witness this milestone moment.

This time, BlockSec CEO Professor Zhou Yajin will bring you dry goods on the content research of stablecoins at the Hong Kong Polytechnic University, AIFT Artificial Intelligence Financial Technology Laboratory, and the Chinese University of Hong Kong from September 4 to September 6, 2024. 👨🏻‍💻

A phishing transaction profited more than 54M Dai! The attacker lures the victim into signing a TX to change the vault owner and then executes a TX to drain the vault!

Be cautious when signing a transaction.
