250 stories about Security from across the crypto press, curated and summarized daily. Most recent: Oct 25, 2026.
A hacker exploited Ostium's price-reporting system to steal $18 million, the latest in a wave of attacks targeting decentralized finance protocols. The attacker manipulated future-dated oracle data to create fake trading profits.
Ethereum developers are using AI agents to analyze and improve the blockchain's protocol code. This approach helps identify bugs and optimize performance, making the network more secure and efficient.
Lending protocol Bonzo Lend lost $9.05 million after an attacker exploited a verification flaw in a third-party Supra oracle contract on the Hedera network. The incident highlights the risks of relying on external data providers in decentralized finance.
Ethereum developers deployed AI agents to hunt for bugs and discovered a vulnerability in libp2p. This highlights how AI is becoming crucial for blockchain security. The vulnerability was found in the libp2p protocol, which is used for peer-to-peer communication in Ethereum and other blockchain networks. The discovery underscores the importance of AI in identifying potential security risks before they can be exploited.
BitGo launched new quantum-risk tools that help institutional Bitcoin holders identify and reduce potential future quantum-computing exposure in their custody wallets.
A new study reveals that 31% of Ethereum's node activity is based in the US, primarily on three cloud providers. If a third of these nodes go offline, it could disrupt the network's finalization process.
Bonzo Lend lost $9 million after an attacker manipulated the value of SAUCE collateral using a flaw in Supra's on-chain oracle verifier. The exploit highlights ongoing risks in decentralized finance (DeFi) platforms.
The Ethereum Foundation deployed coordinated AI agents to scan validator software, uncovering a remotely triggerable crash bug. However, the AI also produced many confident but false findings, requiring human experts to verify the real threat.
The Ethereum Foundation's Protocol Security team is using AI agents to review the blockchain's code. This approach helps identify vulnerabilities and improve security across different Ethereum clients.
Ethereum researchers are using AI agents to hunt for vulnerabilities, shifting security work from finding bugs to proving which ones are real.
Crypto hacks hit a record 207 incidents in the first half of 2026, but total losses fell to $972 million, a significant drop from previous years. DeFi exploits, in particular, saw a 74% decrease in damage compared to 2022, according to Immunefi.
An attacker followed every rule of a crypto system perfectly, drained $20 million from its treasury, and may still go to prison. The incident highlights vulnerabilities in decentralized governance mechanisms.
EDX Markets, a crypto exchange for institutional investors, raised $76 million in a funding round led by SBI Holdings. The platform separates trading from custody via a central clearinghouse to minimize counterparty risk.
An attacker spent $4 million to acquire enough BONK tokens to pass a malicious governance proposal, draining $20 million from the project's treasury. The attacker then began selling the stolen tokens, causing the price to drop.
The developers behind the memecoin project said they had informed law enforcement after the attack and were working to recover funds and identify those responsible.
While crypto hacks decreased by 47% in the first half of 2026, Q2 saw a 59% increase in exploits, totaling $807.5 million. North Korean hackers were behind some of the largest breaches, including attacks on KelpDAO and Drift Protocol.
A security flaw called 'Ill Bloom' could expose thousands of crypto wallets to theft. The issue stems from weak recovery phrase generation, potentially affecting multiple blockchains. Coinspect, a blockchain security firm, discovered the vulnerability.
Summer.fi has paused its Lazy Summer vaults following a $6 million exploit, causing its SUMR token to drop over 18%. The DeFi protocol is investigating the incident and has not yet provided details on the cause or recovery efforts.
Binance founder Changpeng Zhao proposed freezing Satoshi Nakamoto's 1.1 million bitcoin to guard against potential quantum computer theft, but experts are divided on feasibility and necessity.
Researchers discovered a flaw in the Aptos blockchain that could have put $70 billion in crypto at risk. They broke a core security guarantee with a near-90% success rate, using just a $3,000 server. The vulnerability has been patched.
Moody’s says President Trump’s new quantum computing executive orders highlight an urgent need for Bitcoin and the broader digital asset industry to adopt quantum-resistant cryptography.
Taiko has fully restored its cross-chain bridge just 10 days after a $1.7 million hack. The TAIKO token has surged as much as 136% in recent trading, reflecting renewed confidence in the protocol.
Anchorage Digital and Binance have launched an off-exchange settlement service, allowing institutions to trade on Binance while keeping their assets in segregated custody at Anchorage Digital Bank instead of on the exchange. This reduces counterparty risk and enhances security for large-scale crypto trading.
StarkWare's CEO Eli Ben-Sasson criticized the crypto industry for ignoring quantum computing threats and announced a roadmap for Starknet to address these risks. The company aims to make the blockchain more resilient against future quantum attacks.
