Seems bingx CEX been drained

this is old but interesting, if users in berachain blockchain send msg.value less than the amount they set, the MultiSwap contract (the router) will use BERA tokens it holds, which are small and isolated from the pools’ assets. https://x.com/dvzhangtz/status/1815771395328225361 this was patched by a white hat @EthSecurity

The ether.fi frontend has been compromised!

*critical* issue on Bedrock protocol.

The issue was exploited some hours later, but damage was contained.

Vulnerability was in minting uniBTC, a ~$75m asset (on Ethereum alone, plus much more on 8+ other chains).


Issue: Exploiter could mint 1unibtc with 1ether
BTC has 8 decimals, ETH has 18 decimals. If you send 1 ETH you get many times more than 1 BTC. There's not even price conversion involved, since in reality 1 BTC =~ 30 ETH.

Second, if a token is not registered, the contract returns 0, meaning it cannot be found in the tokenHolders variable. The following figure shows that only FBTC, WBTC, and cbBTC have been registered, while NATIVE_BTC has NOT. On one hand, NATIVE_BTC should NOT be registered in this contract, as it is not intended to be supported. On the other hand, failing to register NATIVE_BTC results in the totalSupply always being ZERO, which contradicts the caps restriction mechanism.

Since the total supply at that time was ZERO instead of reflecting the msg.value received by the contract, the check the Vault contract passed, allowing the minting of uniBTC using native tokens on non-native BTC chains.

Therefore, on a non-native BTC chain, replacing the balance with the total supply is acceptable for wrapped BTC tokens but problematic for native tokens.

"We have developed Web3AuthChecker, a dynamic detection tool that interacts with Web3 authentication-related APIs to identify vulnerabilities.

Our evaluation of real-world Web3 applications shows that a staggering 75.8% (22/29) of Web3 authentication deployments are at risk of blind message attacks." https://arxiv.org/pdf/2406.00523 @EthSecurity1

eigenlayer : In an isolated incident this morning, an email thread involving one investor’s transfer of tokens into custody was compromised by a malicious attacker.

As a result, 1,673,645 EIGEN tokens were erroneously transferred to the attacker’s address. The attacker sold these stolen EIGEN tokens via a decentralized swap platform and transferred stablecoins to centralized exchanges. We are in contact with these platforms and law enforcement. A portion of the funds have already been frozen.

The compromise has not impacted the broader ecosystem. There is no known vulnerability in the protocol or token contracts and this compromise was not related to any onchain functionality.

We continue to investigate the situation and will be posting further information once we have it. @EthSecurity1

Unverified contract lost $280k due to sandwich attack.There's a function that can be used for swapping WBNB to EGA token in victim contract. This function has no access control, anyone can call this function with only 1 wei. This is vulnerable to
