A Coinbase report warns that millions of Bitcoin are vulnerable to quantum attacks due to address reuse, including exchange cold wallets. The report suggests freezing exposed coins and setting migration deadlines to mitigate the risk.
A $36 million hack on Humanity Protocol may involve North Korean hackers, according to security firm Quantstamp. The attack used a fake Bithumb email to execute the theft.
A Coinbase-convened panel of top cryptographers agrees Bitcoin should start preparing for quantum attacks now, but declines to take a position on whether millions of vulnerable coins, including many linked to Satoshi Nakamoto, should eventually be frozen.
A new analysis from ChainQuery reveals that 25.3% of all Bitcoin is stored at addresses where the public key has been exposed, making those funds potentially vulnerable to future quantum computing attacks. The risk is not immediate but highlights a significant security consideration for long-term holders.
Coinbase's quantum advisory council urges immediate action to protect Bitcoin from future quantum computing threats. Developers must start migrating to post-quantum cryptography now to avoid potential vulnerabilities. The biggest challenge will be addressing abandoned and vulnerable coins.
The rise of advanced AI models is causing a spike in DeFi hacks, according to Immunefi CEO Mitchell Amador. These tools are making it easier for attackers to exploit vulnerabilities in crypto projects.
Citi analysts warn that Bitcoin's security could be at greater risk from quantum computing than Ethereum's. The concern stems from Bitcoin's reliance on elliptic curve cryptography, which may be more vulnerable to quantum attacks.
Chainalysis, a leading blockchain analytics firm, has teamed up with South Korea's national police to tackle crypto-related crimes, including those linked to North Korea. This collaboration aims to enhance the country's ability to track and prevent financial crimes involving digital assets.
The Stellar Development Foundation has released a three-step plan to protect its blockchain from future quantum computing threats. This move highlights the growing concern about quantum computers breaking current cryptographic defenses.
Researchers from the Initiative for CryptoCurrencies and Contracts (IC3) warn that autonomous AI agents with access to cryptocurrency could become 'unstoppable,' posing far-reaching risks to users and the financial system. The warning highlights the urgent need for robust security measures in AI and crypto integration.
Humanity Protocol suffered a $36 million hack after an employee's laptop was compromised, allowing attackers to seize control of bridges and mint tokens at will. The protocol's token (HMT) crashed 73% following the breach.
The Bored Ape Yacht Club creator now holds more than 60 rescued NFTs in its custody as it works to return them to their rightful owners.
Zcash's price surged 42% after the team fixed a critical vulnerability in its privacy-focused Orchard shielded pool. The upgrade required a two-step process to ensure network security and stability.
MetaMask has introduced a new self-custodial wallet designed for AI agents to trade across DeFi while keeping users in full control of their funds and approvals. This innovation aims to make decentralized finance more accessible and secure.
Fallout from a bug that enabled undetectable Zcash counterfeiting shows that privacy can sometimes present tradeoffs, experts say.
A security researcher discovered a critical vulnerability in Zcash that could have enabled unlimited counterfeit coin creation. The bug was fixed within days, and findings suggest that actual exploitation of the bug is unlikely. ZEC's price dropped 31% on the news.
Taylor Hornby, who uncovered the Orchard flaw that sent Zcash down 38%, says other privacy coins are on his list too.
Zcash developers are considering a new shielded pool and turnstile accounting to address a recent bug that allowed counterfeit transactions. This follows concerns about the supply verification process in the Orchard protocol.
Strategy (formerly MicroStrategy) sold a portion of its Bitcoin holdings for the first time since 2022, citing emerging quantum computing risks. The company's stock dropped following the announcement, highlighting investor concerns about the security of Bitcoin in the face of advancing technology.
An AI model discovered a four-year-old vulnerability in the Zcash cryptocurrency network, prompting warnings that similar flaws could exist in other crypto and traditional financial systems. Security experts urge immediate attention to potential risks across the financial sector.
A well-known crypto security pioneer has publicly stated that they now consider all of decentralized finance (DeFi) unsafe. This comes amid rising concerns about vulnerabilities and exploits in the space. The expert cited recent high-profile hacks as a major reason for their stance.
Radiant Capital is shutting down after failing to recover funds from a roughly $50 million hack in 2024. The company couldn't raise new capital or recover a meaningful amount of the stolen assets.
Gnosis Pay is facing an active exploit in its delay module, but the team has pledged to fully refund affected users. Co-founder Martin Köppelmann initially urged users to withdraw funds but later walked back the warning.
The Kelp DAO hacker has laundered nearly all of the remaining stolen funds, making recovery unlikely. Only $71 million, frozen by Arbitrum’s Security Council, remains from the original $293 million exploit.
