A sophisticated hacking group linked to North Korea has stolen over $12 million in cryptocurrency from unsuspecting users. The campaign involved phishing and social engineering tactics to trick victims into revealing their private keys.
THORChain has confirmed a $10 million exploit and launched a recovery portal for affected users. The portal allows users to revoke malicious approvals and claim refunds across four blockchain networks.
Many crypto users are opting for high-yield investments over DeFi insurance, leaving billions at risk. This trend has led to the collapse of most DeFi insurance protocols, which were meant to protect against hacks and exploits.
Lombard is the latest project to abandon LayerZero's cross-chain bridge, shifting $4 billion to Chainlink's alternative. This follows a $292 million exploit on LayerZero's Kelp DAO bridge, raising security concerns.
The KelpDAO hack, totaling $293 million, highlights a shift in DeFi security challenges from coding bugs to managing complexity. This incident underscores the need for more robust security measures as DeFi protocols mature.
Lombard Finance is shifting its $1 billion in Bitcoin assets from LayerZero to Chainlink after a major exploit. The move comes following the Kelp DAO hack, which resulted in a $292 million loss.
Kraken is abandoning LayerZero's technology for its wrapped Bitcoin service, joining a wave of firms leaving after a $292 million hack. The exchange will now use Chainlink's cross-chain tech instead.
DeFi attackers are using AI to exploit security weaknesses beyond smart contract bugs, making it harder for defenders to keep up. The CEO of CertiK warns that this creates an unfair advantage for hackers.
Kraken is moving over $3 billion in assets from LayerZero to Chainlink after a $292 million exploit. This shift follows a security breach on a LayerZero-powered bridge involving the Kelp project.
A new Ethereum standard called Clear Signing aims to prevent blind signing, a flaw that has led to billions in losses. The initiative involves major wallet developers, security firms, and the Ethereum Foundation.
Ethereum developers have proposed a solution to 'blind signing,' a technical flaw that has led to significant financial losses. This change could make the network safer for everyday users.
Elliptic, a blockchain analytics firm, has raised $120 million in a Series D funding round, valuing the company at $670 million. Deutsche Bank and Nasdaq Ventures are among the major investors, signaling growing interest from traditional financial institutions in the crypto space.
