US President Trump signed two executive orders on Monday aimed at accelerating the nation's quantum computing capabilities and advancing the migration of government systems to post-quantum cryptography. While the orders do not directly mention Bitcoin, industry insiders believe this could benefit blockchain post-quantum security research and development.The two executive orders focus on defending against advanced cryptographic attacks and driving the frontier of quantum innovation. This includes a clear timeline: advancing quantum sensor construction by September 2028, and requiring federal high-value assets and high-impact systems to complete their post-quantum cryptography migration by the end of 2031.Alex Pruden, CEO of Project Eleven, stated that this means the US government will allocate funds and time to achieve post-quantum security goals. It may also extend these requirements to the entire federal contractor system, not just government agencies, thereby accelerating the practical application of post-quantum cryptographic technology.This policy comes amid growing attention within the blockchain industry to quantum threats. The Ethereum Foundation, Solana Foundation, and others have already begun advancing post-quantum security R&D, while the Bitcoin community is also discussing potential risks. Some Bitcoin held in publicly exposed addresses is considered vulnerable to private key derivation attacks once sufficiently powerful quantum computers emerge.Pruden noted that this executive order sets a clear deadline of 2031 for the adoption of post-quantum cryptography, which is more enforceable than the previous US government guidance which only proposed phasing out traditional cryptographic systems by 2035. For Bitcoin and the broader crypto industry, government-level investment in post-quantum security could accelerate the maturation of related tools, standards, and migration pathways.
Odaily, the decentralized cross-chain liquidity protocol THORChain has resumed trading after being down for over five weeks following a May attack. Signing, swapping, liquidity provider operations, and redemptions have all been restored.On May 15, blockchain investigator ZachXBT and security firm PeckShield identified that the protocol had likely been exploited, prompting THORChain to halt trading. The vulnerability resulted in a loss of approximately $10.7 million from one of its six Asgard vaults, while the other five vaults were unaffected.THORChain stated that each vault has now been verified, and every key share has been cross-checked. Native Monero swaps are currently undergoing end-to-end testing and will be launched subsequently. (The Block)

according to DefiLlama data, Q2 2026 has become the most active quarter on record for crypto hacks, with 83 separate attack incidents, setting a new all-time high.Despite the increased frequency of attacks, the total losses for the quarter were approximately $755.3 million, still lower than the $3.56 billion lost in Q4 2020. Of this, the $293 million attack on KelpDAO and the $280 million attack on Drift Protocol accounted for more than three-quarters of the quarter's total losses. Cross-chain bridges were the largest source of losses, with related attacks leading to approximately $351 million being stolen. Earlier this month, Humanity Protocol lost $36 million, Aztec Connect experienced two attacks on passive smart contracts, each losing about $2.1 million, and decentralized exchange Raydium suffered a $1.3 million attack in June.

Odaily Odaily News: Jiangsu Nanjing police, in collaboration with the Chongzuo Border Management Detachment in Guangxi, successfully solved a major gold theft case involving 27 million yuan. The masterminds, Wang and Tong, driven by massive gambling debts, teamed up with another accomplice to plan and execute a theft targeting a luxury store in Jiangning District, Nanjing. They stole a total of 37 gold items, weighing 27 kilograms.After the crime, the main suspect Tong fled south with part of the gold by ride-hailing car, attempting to cross the border illegally via a small path. He was precisely intercepted and arrested by police from the Chongzuo Aidian Border Police Station just 100 meters from the China-Vietnam border, with 8.75 kilograms of gold seized on the spot. Subsequently, another suspect, Wang, who had already fled to Thailand, was captured in Bangkok and extradited back to China. Currently, all 11 suspects in the case have been apprehended, and the 27 kilograms of stolen gold have been fully recovered. (China News Weekly)
Taiko stated that the related security incident is currently under control. The cross-chain bridge and vault have been paused, and funds cannot be withdrawn further. The cross-chain bridge is currently offline in both directions; users are advised not to perform any cross-chain operations for now. The official announcement noted that pending transactions have been paused—not lost—and further information will be released shortly.
Ethereum Layer 2 blockchain Taiko has stated its chain state verification mechanism has been compromised, and the security assumptions of all bridges deployed on Taiko can no longer be relied upon. It urges users to immediately withdraw funds from the relevant bridges. Taiko says it is coordinating with partners to control the incident and has suspended the affected systems.Crypto security firm Blockaid stated that the root cause appears to be a flaw in the way Taiko's bridge validates source signals. Attackers can submit message proofs on Ethereum that lack legitimate proof from the Taiko chain, thereby registering and withdrawing fraudulent bridge messages. This leads to the unauthorized release of assets from the ERC20 treasury. Blockaid estimates at least $1 million was stolen, while Lookonchain and PeckShield believe the value of stolen assets could be as high as $1.7 million.PeckShield reported that the attacker has transferred approximately 1.99 million TAIKO tokens to MEXC, valued at around $189,000. Data from blockchain intelligence firm Arkham shows that the Taiko attacker's wallet holds approximately $1.5 million in assets, primarily in Ether. (Cointelegraph)

According to on-chain analyst PeckShield (@PeckShieldAlert), the well-known MEV bot “JaredFromSubway” has reportedly been attacked, resulting in the theft of approximately $7.5 million worth of crypto assets—including 1,474.58 WETH, 2.87 million USDC, and 2 million USDT. The attacker has exchanged the stolen funds for 4,400 ETH and transferred 1,000 ETH to the mixer Tornado Cash to obfuscate the fund’s trail.
Jaredfromsubway.eth, a well-known MEV bot long active on the Ethereum network, has been attacked by hackers exploiting a vulnerability in its automated execution system, resulting in losses exceeding $7.5 million.Security firm Blockaid stated that the incident was not a traditional phishing attack or smart contract vulnerability, but rather an "anti-MEV honeypot attack" specifically targeting the decision-making logic of the MEV bot. Over several weeks, the attacker deployed 66 fake token contracts and false liquidity pools, masquerading as assets such as WETH, USDC, and USDT, luring the bot into executing seemingly profitable trades and authorizing auxiliary contracts controlled by the attacker.Ultimately, in a single transaction, the attacker invoked all backdoor permissions to transfer the ETH, USDC, and USDT held by the bot's address. Data shows that between November 2024 and October 2025, the Ethereum network experienced approximately 60,000 to 90,000 sandwich attacks per month, with about 70% of them linked to Jaredfromsubway.eth.

According to the “Mousetrap” platform, scammers impersonated Moscow Exchange-authorized brokers on social media and lured users into clicking phishing links under the pretext of a “cryptocurrency test trading channel,” thereby stealing funds and information. The Moscow Exchange emphasized that all official trading must be conducted through licensed brokers and that no exclusive cryptocurrency purchasing channels exist for ordinary users. According to data from Russian IT company “Shard,” Russian users lost approximately 234 million rubles to cryptocurrency phishing attacks in 2025—accounting for 62% of total cryptocurrency-related losses that year.
According to on-chain analyst Blockaid (@blockaid_), the well-known Ethereum MEV bot JaredFromSubway (@jaredsmev) has been attacked, resulting in losses of approximately $7.5 million. The attacker constructed a deceptive MEV arbitrage path to trick the bot into automatically approving token transfers. Leveraging these open approvals—before they were revoked—the attacker drained WETH, USDC, and USDT from the bot’s contract. The stolen funds ultimately flowed to the attacker’s wallet address. Blockaid noted that this attack was not a conventional phishing attempt or smart contract vulnerability, but rather a targeted exploitation of the bot’s automated execution mechanism.
