: Anthropic's Claude Mythos Preview model discovered a flaw in the proposed HAWK digital signature scheme, effectively halving its minimum key strength. HAWK is one of the candidate schemes to replace current network and bank signatures in a post-quantum environment. This AI-driven attack took approximately 60 hours, with a computational cost of around $100,000, reducing the effort required to break HAWK's minimum parameter set from roughly 2^64 operations to 2^38 operations, and diminishing the attractiveness of larger compensating key sizes. Current Bitcoin and Ethereum signatures remain unaffected. The results indicate that the capabilities of classical cryptanalysis attacks are improving, while Bitcoin and other networks continue to discuss when and how to migrate to quantum-resistant cryptography.
According to Ostium's official report, the core of this attack lies in the compromise of the off-chain price reporting system permissions, unrelated to smart contract vulnerabilities. After obtaining off-chain authorization, the attacker utilized the protocol's registered legitimate forwarding paths to submit forged prices ($5,000 and $60,000) to the BTC-USD market, atomically completing an open-close position arbitrage cycle within the same transaction. Starting with 100 USDC and rolling to amplify the scale across 8 transactions, they extracted 23.75 million USDC from the OLP vault within 5 minutes until the vault circuit breaker mechanism was triggered. The root cause lies in the off-chain infrastructure lacking a multi-party approval mechanism equivalent to on-chain multi-signature, creating a single-point permission vulnerability. The stolen funds have been converted to ETH and mixed via Tornado Cash; tracking efforts are still ongoing.

: A security report for the first half of 2026 released by on-chain security platform Blockaid shows that the crypto industry suffered losses exceeding $1 billion during the period, with a record number of hacker incidents in six months. Blockaid tracked 212 security incidents, including a single attack on KelpDAO that resulted in a loss of $292 million. Ethereum and Solana were the networks with the largest amounts of stolen funds during the period, with losses of approximately $332 million and $326 million, respectively. Blockaid stated that the number of high-threshold attacks in the first half of 2026 was 3.4 times that of the entire year of 2025. Ethereum incidents were primarily driven by code vulnerabilities, with attack vectors including bridge and smart contract exploits, unauthorized access to privileged accounts, and market manipulation. Solana's losses increased significantly from approximately $127 million in 2025, with over 98% of losses stemming from key leaks, primarily involving incidents related to Drift Protocol and Step Finance.
据 PeckShield 监测，Across Protocol 攻击者标记地址已向 Across Protocol Hub Pool Owner 多签地址返还 331.8 枚 ETH，约合 62.39 万美元。
According to Cointelegraph, the cross-chain bridging and atomic swap protocol Garden Finance temporarily took its application offline after detecting abnormal activity on July 27. Blockchain security firm Blockaid disclosed that attackers exploited a vulnerability in Garden Finance's Hash Time Locked Contracts (HTLC), stealing a total of approximately $450,000 worth of USDT across four networks: Ethereum, Base, Arbitrum, and BNB Smart Chain.
According to on-chain analyst PeckShield (@PeckShieldAlert), the address labeled "Drift Exploiter" has deposited 23,095.1 ETH (approximately $44.4 million) into Tornado Cash for mixing, and additionally transferred 0.85 ETH to Bybit.
on-chain security analyst Specter has detected that a long-dormant PancakeSwap liquidity provider (LP) suffered a loss of approximately $2.96 million after signing a malicious EIP-7702 authorization. It is reported that the attacker removed approximately $1.48 million in BSC-USD and $1.48 million in BUSD liquidity provided by the victim, subsequently swapping the BUSD for ETH. Currently, the attacker has deposited approximately $1.46 million into Tornado Cash, while the remaining $1.48 million in USDT remains in the attacker's address.
Odaily News: Ethereum Layer 2 network Taiko released a post-mortem of the June 21 security incident, stating that the attack resulted from an off-chain signature key leak and a verification process gap. The attacker exploited these to forge proofs and bypass the Prover whitelist, rather than breaking ZK cryptography or smart contracts. The attacker stole approximately $1.75 million from cross-chain bridges and Vaults, but over $11 million in assets were protected, and no user funds were lost. Taiko has fixed the vulnerability, restored the pre-attack state, and resumed operation on July 2; an OpenZeppelin audit confirmed the fixes with no high, medium, or low-risk vulnerabilities identified. The official statement also indicated that the Unzen upgrade, scheduled for August 6, will require ZK proofs for every block to further enhance network security.
that, according to Onchain Lens monitoring, after a $285 million attack on Drift Protocol on Solana in April, the attacker has begun moving funds through Tornado Cash following a 3-month dormant period. The attacker is rapidly depositing ETH into the Tornado Cash Router in batches of 100 ETH, with multiple transactions occurring per minute.
According to Lookonchain statistics, 3 security incidents have occurred in the crypto industry today, with cumulative losses of approximately $35.55 million. Among them, AFX Trade was attacked with losses of approximately $24.15 million, Verus's Ethereum cross-chain bridge was attacked with losses of approximately $7.55 million, and B² Network was attacked with losses of approximately $3.86 million.
According to CertiK Alert monitoring, a security incident occurred on VerusCoin's Ethereum cross-chain bridge, with approximately $7.53 million in assets transferred out. Preliminary analysis indicates that this issue may be related to the cross-chain bridge failing to sufficiently verify whether the Verus chain-side input supports the paid amount, similar to an incident that occurred in May this year.
: According to on-chain detective Specter’s monitoring, B² Network may have suffered a vulnerability exploit on BNB Chain. The attacker transferred 8.591 million B2, worth $3.86 million, and exchanged them for 5,409 WBNB, worth $3.11 million. The funds were then bridged to Ethereum, and are currently being transferred to Zcash via NEAR Intents. The addresses used for the theft are 0xEc443f7D79835B464FBEAC798d3f92B62d6Ff433 and 0xf977427Ec8e583C55D413061FC205BCD57e8Bf6D.
According to on-chain analyst Specter, B² Network on BNB Chain suffered a hack, resulting in a loss of approximately 8.591 million B2 tokens (approximately $3.86 million). The attacker swapped them for 5409 WBNB (approximately $3.11 million) and bridged to Ethereum, and is currently transferring the funds to Zcash via NEAR Intents.
according to Onchain Lens monitoring, on July 6, the Summer Fi attacker received 6.017 million DAI from the Summer Fi exploit, and subsequently swapped and routed the funds through Tornado Cash. The original wallet (0x7bf...dca) retains 11.3 ETH, worth approximately $21,600; the second wallet (0x46e...ba7) retains 282.9 ETH, worth approximately $543,500.
according to Hinkal monitoring, full refunds will be issued this week to users who have completed the recovery process, with completion expected by July 22. Users who have not yet completed the recovery can still submit applications. Previously, Hinkal suffered an attack resulting in a loss of approximately 797,000 USDC, which the attacker exchanged for about 454 ETH.
According to Com Feed monitoring, the TrustedVolumes attacker has returned 1,122 ETH, worth approximately $2 million, while retaining about $2 million as a "bounty." Previously, the attacker had exploited a vulnerability to steal approximately $5.8 million in funds.

DeFi infrastructure company Enso disclosed a type of malicious liquidity pool called "toxic pools" in a report on July 16th. These pools manipulate transaction simulations to return false optimal quotes to wallets and DEX aggregators, subsequently altering the logic during actual on-chain execution. Enso stated that the relevant malicious contracts can identify read-only simulation environments and return optimized prices, but when the transaction is broadcast on-chain, it is executed at a worse price or causes the transaction to fail. One manipulated Curve pool processed over 129,000 swaps, resulting in approximately $225,000 in inflated quotes. Additionally, over 37,000 transactions were reverted, consuming nearly $30,000 in gas fees. On Polygon, a malicious Uniswap v4 hook attracted routing systems with fake exchange rates, subsequently triggering a 99.1% transaction failure rate. Enso stated that it has updated its execution protection product, Enso Shield, to detect fake quotes in Ethereum and Polygon environments.
Odaily reports, according to Onchain Lens monitoring, the ResolvLabs attacker has moved funds again after stealing approximately $25.9 million in March. Over the past few hours, 580 ETH, worth about $1.09 million, has been transferred and is being routed through a mixer.
