Major Security Incidents in November
MetaWin
On November 4, 2024, blockchain investigator ZachXBT reported that crypto gambling platform MetaWin was hacked, resulting in over $4 million stolen on Ethereum and Solana chains. According to MetaWin CEO Skel, the attackers exploited the platform‘s frictionless withdrawal system to breach MetaWin’s hot wallet.
DeltaPrime
On November 11, 2024, DeFi protocol DeltaPrime was attacked on Avalanche and Arbitrum, with an estimated loss of $4.75 million. The root cause of the attack was the lack of input validation in the reward claim function.
Thala
On November 15, 2024, Aptos-based DeFi project Thala was hacked, resulting in $25.5 million in losses. The attackers exploited a vulnerability in the projects smart contract. The team halted affected smart contracts and froze approximately $11.5 million in assets. After working with law enforcement and blockchain security teams, the project recovered a significant portion of the stolen funds, allowing the attacker to keep $300,000 as a bounty.
DEXX
On November 16, 2024, several users of the DEXX on-chain trading terminal reported stolen funds. According to SlowMist security team statistics, the losses amounted to $21 million. SlowMist is assisting DEXX and its partners in ongoing investigations. On November 28, SlowMist released data identifying 8,612 attacker addresses on the Solana chain, with attacker addresses on EVM chains to be disclosed after further analysis.
Polter Finance
On November 17, 2024, Fantom-based DeFi project Polter Finance was hacked, incurring losses of approximately $12 million. The attacker exploited a flash loan to deplete BOO token reserves, artificially inflating its price. This allowed them to borrow tokens far exceeding the collateral‘s actual value, profiting massively. The platform’s founder stated that they had filed a report with Singaporean authorities and reached out to the attacker via on-chain messages for negotiation, but no response has been received.
AI Poisoning Attacks Alert
While the number of security incidents and associated losses decreased compared to the previous month, the SlowMist security team observed genuine AI poisoning attacks targeting the crypto industry. Developers, in their pursuit of efficiency, may have overly relied on AI-generated code without adequately auditing its security.
