The topic of scaling Bitcoin dates back to its very first mailing post. In response to Satoshi’s original message, James McDonald said, “We very, very much need such a system, but the way I understand your proposal, it does not seem to scale to the required size” — a remark that probably wasn’t the welcome Satoshi had anticipated. Nonetheless, this marked the beginning of a seemingly never ending, complex debate.
Optimism (OP) is a Layer-2 Ethereum scaling protocol. It aims to increase Ethereum’s transaction throughput while decreasing transaction costs via Optimistic Rollups.
PeckShield has monitored that the fake token Notcoin (NOT) on Ethereum has dropped 100%. An address starting with 0xE0eB sold 1,645,040,633,338,481.95 NOT and exchanged it for 93.5 WETH (valued at $281,000 USD). Note: Rugpull tokens have the same name as legitimate tokens.
According to PeckShield's monitoring, Sonne Finance hacker address 0x6277...4c07 has exchanged 56 WBTC for approximately 1,185 ETH and 3 WBTC for 183,000 DAI.
Sonne Finance released an attack analysis report. This was a donation attack. Sonne had avoided this problem in the past by adding a collateral factor of 0% to the market, adding collateral and then destroying it, and only then increasing c-factors according to the proposal. Sonne recently passed a proposal to add the VELO market to Sonne. This transaction was arranged on a multi-signature wallet, and c-factors were arranged to be executed within 2 days due to the time lock. When the 2-day time lock for creating the market ended, the attacker executed 4 of the transactions and then executed the transaction to add c-factors to the market. The attacker was able to use the protocol to obtain approximately $20 million in funds through a known donation attack. Seal contributors quickly noticed this issue and reserved approximately $6.5 million by adding VELO worth approximately $100 to the market. Sonne is investigating the attacker and has suspended the market to mitigate further losses. Sonne is prepared to offer a bounty to the attacker and promises not to pursue the issue further if the attacker returns the funds.
On May 15th, Sonne Finance announced that its Optimism protocol had suffered a known donation attack, resulting in a loss of approximately $20 million. The attack exploited a vulnerability in the newly launched market and within two days of its creation, the attacker used a multi-signature wallet and time-lock function to execute critical transactions, successfully manipulating the market's collateral factors (c-factors). Despite Sonne's team quickly organizing a response to the attack and suspending the market within 25 minutes of discovering the issue to minimize further losses, approximately $6.5 million in funds were still retained. Sonne's team is working hard to track down the identity of the attacker and has offered a bounty to the attacker in the hopes of returning the funds to avoid further investigation. At the same time, Sonne's team sincerely apologizes for this incident and is reaching out to all possible partners to try to recover the funds.
According to CertiK monitoring shows that due to suspicious transactions, preliminary evidence suggests that the private key may have been leaked, and a total of approximately $4.3 million worth of assets have been transferred to the address 0x2705.
According to Chainalysis, by 2023, approximately $24 million worth of cryptocurrency will be stolen through impersonation and tax authority scams. The company estimates that as of April 2024, the total amount stolen will be close to $17 million.
The hacker who stole over $130 million in assets from the DeFi project BXH on October 30, 2021, transferred 9,491 ETH (worth $31.38 million) through Tornado Cash five hours ago, as monitored by blockchain analyst Yu Jin. The hacker collected a total of 9,491 ETH through three addresses and deposited all of these ETH into Tornado Cash through the 0xda9...ad3 address.
