Although the $450,000 theft is relatively small compared to some other crypto hacks, it represented around 6% of the total value locked on Clipper. Clipper stated they were working to trace and attempt to recover funds, and asked the hacker to contact them to potentially negotiate a return of some funds.

The Clipper decentralized exchange suffered a $450,000 exploit across two Ethereum layer-2 chains.

13-year-old rug pulls crypto token, then faces retaliation
A 13-year-old known as the "Gen Z Quant kid," created a token called QUANT and executed a rug pull, making $30,000. In retaliation, various people in the cryptocurrency world executed a "revenge pump" — pumping up the price of the token after the kid cashed out, causing him to miss out on potential gains. Worse, they then found the child's identity, and published his address and the school he attended. They also identified his mother, and began leaving hateful comments on her Instagram account. Rumors also emerged that a member of the cryptocurrency community dognapped the child's dog, then launched a memecoin based on the animal.

Polter Finance exploited for $12 million
The Fantom-based Polter Finance defi project was exploited for $7 million when an attacker was able to perform an oracle manipulation attack. By artificially increasing the price of the $BOO token, which is a governance token used by the SpookySwap project, they were then able to use that token to drain Polter's liquidity pools using a flash loan. The attacker successfully drained the entire $12 million worth of tokens on the platform.
The creator of the platform stated that they had filed a police report with Singaporean authorities. They also attempted to contact the hacker via on-chain message to negotiate the return of funds, but have not received a response.
Thala Labs loses, then recovers, $25.5 million
The Thala Labs Aptos-based defi project suffered a $25.5 million theft when an attacker exploited a vulnerability in one of their smart contracts. They paused related smart contracts and froze tokens where they were able, ultimately freezing around $11.5 million in assets. After working with law enforcement and several blockchain security teams, they successfully negotiated the return of the assets, leaving the attacker with a "bounty" of $300,000.
DeltaPrime loses $4.8 million in second hack
The DeltaPrime defi protocol was hacked for the second time in two months, losing $4.8 million in Arbitrum and Avalanche tokens. The attacker appeared to have exploited a flaw in one of the platform's smart contracts that enabled them to borrow more than they put up in collateral.
DeltaPrime paused the protocol on both Arbitrum and Avalanche, stopping the attacker from being able to steal more funds than they already had.
DeltaPrime was hacked previously on September 16, losing $6 million after a leaked private key enabled an attacker to mint a huge number of the platform's stablecoin deposit receipts.
Trader reveals he lost $28 million to bad copy-paste
After apparently exhausting all his other options, a trader has put out a call to "all skilled hackers and white hats out there" to help him recover 7,912 Renzo staked ETH (ezETH) he inadvertently sent to an inaccessible address back in June. The tokens were priced at a little over $28 million at the time, and are currently priced at a little less than $26 million. According to the trader, he copied the wrong address to his clipboard before making the trade, which rendered his funds permanently inaccessible.
Short of finding a vulnerability in Renzo, the trader's only real choice is to plead with Renzo to change their smart contract in such a way as to release the funds. While this is technically possible, Renzo has told the trader they could not grant his request due to "regulatory limitations".
CoinPoker exploited for $2 million
