PeckShield tracked 30 major hacking incidents across the crypto industry in July, with total losses reaching $210.3 million. The figure was up 177.2% from June, when losses stood at $75.87 million. Among the incidents listed, the COLDCARD case accounted for about $70 million, making it the third-largest cryptocurrency theft recorded so far this year, according to the update cited by ChainCatcher. Other large losses in July included AFX Trade on Arbitrum at about $24 million, Ostium at about $24 million, BONK at about $21.2 million, and Wanchain at about $13 million. The list also included Triple-A, Bonzo Lend, Verus, WEMIX, and Summer.fi, each with reported losses ranging from roughly $6 million to $10 million. The figures were published in a market security update referenced by ChainCatcher.

WEMIX has released a fresh update on the WEMIX$ security incident, saying the breach stemmed from a vulnerability in publicly visible on-chain smart contracts rather than an intrusion into internal systems or a leak of administrator private keys. According to the company, ownership of two contracts, DIOS and AMA, was transferred to an unauthorized third party on July 26. DIOS is designed to help maintain WEMIX$ price stability, while AMA supports 1:1 exchanges between WEMIX$ and collateral assets. WEMIX said the attacker deployed a malicious contract in a single transaction, took control of both contracts, and then carried out nine rounds of flash loans and swap transactions. The result was the unauthorized minting of 5,225,524.9997 WEMIX$. The attacker then moved roughly 723,244 USDC.e and 34,752 WEMIX. WEMIX said transactions involving game tokens linked to WEMIX$ are still under review, and more details will be shared once the scope of impact and compensation amount are confirmed. The team has revoked WEMIX$ minting authority, identified the attacker’s address, asked exchanges that received the funds to blacklist it, and filed a formal report with law enforcement. Earlier reports said the funds had been bridged to Ethereum and BSC.

TechFlow’s July 27 briefing pulled together a broad set of signals across semiconductors, AI, crypto, macro and large-cap tech. The headline move came from Changxin Technology, whose first trading day surge of 472% pushed its market value above RMB 3.3 trillion, making it the new market-cap leader in China’s A-share market and the first semiconductor hard-tech company to hold that position in 35 years. The report also highlighted Samsung’s review of Chinese DRAM suppliers for its Galaxy A lineup, SK hynix’s position at Kioxia, and expectations that Samsung and SK hynix could post combined second-quarter profits above KRW 150 trillion, alongside large industry cooperation figures tied to memory, foundry and packaging. In AI, the digest pointed to a leaked Claude Opus 5 system prompt reportedly reaching 200,000 characters, Hugging Face’s demand that OpenAI provide $100 million worth of compute after an attack, Moonshot AI’s Kimi-K3 launch on Hugging Face, and the formation of an open safe AI alliance by 37 companies including Nvidia, Microsoft and IBM. In crypto, Bitcoin returned to $65,000 as oil prices fell after a pause in U.S.-Iran exchanges, WEMIX suffered an exploit involving its minting contract admin account, and Aster DEX revised tokenomics to direct 99% of platform fees to ASTER buybacks for stakers while burning team tokens on a 1:1 basis.

WEMIX has disclosed a fresh update on its recent exploit, saying the attacker obtained owner privileges on July 26 and minted about 5.225 million WEMIX$. The assets were then swapped into WEMIX and USDC.e, bridged to Ethereum and BNB Chain, and sold, with part of the funds ending up at exchanges. In response, the project has suspended all bridge services and liquidity pool trading. WEMIX also said multiple exchanges have frozen related addresses at its request, though it has not disclosed how much has been traced or recovered. The cause of the incident is still under investigation. The update follows earlier reports that more than 5 million tokens had been illicitly minted, and was cited by Techub with reference to crypto.news.

PANews’ July 27 daily roundup spans regulation, project updates, market commentary, and on-chain flows, with CXMT’s blockbuster stock market debut and several large Ethereum purchases taking center stage. CXMT closed its first trading day up 465.82% at 49 yuan, logged 141.187 billion yuan in turnover, reached a 3.28 trillion yuan market capitalization, and overtook Industrial and Commercial Bank of China to become the largest A-share company by market value. In crypto regulation, the U.S. Commodity Futures Trading Commission said prediction-market operators should not rely on template-style self-certifications for event contracts, while at least 29 overseas crypto exchange apps were reportedly blocked from new installation on Google Play in South Korea. On the project side, Binance Alpha said it would list AEON and offer an airdrop to eligible users, Storj Labs filed for Chapter 11 restructuring, and WEMIX said contract ownership had been compromised, leading to the unauthorized minting of more than 5.22 million WEMIX. On-chain data in the roundup also showed one address buying 9,046.17 ETH and three newly created wallets buying another 25,425 ETH at an average price of $1,968.

WEMIX has confirmed a security incident involving compromised smart contract owner permissions, which allowed an attacker to mint and move tokens worth about $6.25 million. According to Techub News, citing WuBlockchain, the exploit was carried out after the attacker obtained owner-level control over the contract. The team has acknowledged the breach and said an investigation is now underway. It has not disclosed any progress on fund recovery so far. WEMIX also said it is still assessing the scope of the impact and advised users to watch for follow-up statements through official channels for the latest response measures.

A wide set of crypto, equity and AI developments shaped the July 27 news cycle. BitMart said it will wind down its exchange in phases, with new registrations, deposits and fresh orders already set to stop and all trading services ending on Aug. 26, 2026, while withdrawals remain open. Around the same time, Odos and Dango each published shutdown timetables, including read-only periods, trading cutoffs and fund withdrawal arrangements. Elsewhere, ChangXin Technology is set to list today at RMB 8.66 per share, with single-lot profit estimates ranging from roughly RMB 12,000 to RMB 20,200 based on different IPO gain benchmarks cited by Chinese media. Robinhood is also in talks with Crypto.com over a prediction-market partnership, according to The Wall Street Journal, and Binance Research said Gen Z is now the largest user group for its equity-linked products, contributing $80 billion in cumulative trading volume. The broader digest also covered Nvidia’s open-weight AI letter, OpenAI and Anthropic’s reported lobbying on open-source models, expected record earnings at SK hynix, Storj Labs’ Chapter 11 filing, a suspected security incident on WEMIX 3.0, and Fidelity’s call for the U.S. Senate to pass the CLARITY Act.

A dense stretch of crypto news from July 26 to July 27 put regulation, platform risk, token supply and exchange transparency in focus. In South Korea, at least 29 offshore crypto derivatives exchange apps became unavailable for new installation through Google Play, expanding restrictions already affecting names such as OKX and Bybit. The report said users in Korea now see messages that the apps are unusable or unavailable in their region, while browser access and Apple App Store distribution remain unaffected. Since January, Google has applied region-specific support suspensions to virtual asset service provider apps that are not registered with the country’s Financial Intelligence Unit. In the U.S., the Commodity Futures Trading Commission’s Division of Market Oversight issued new guidance for prediction-market platforms including Kalshi, Coinbase, Polymarket and Crypto.com, warning against broad, template-based self-certifications for event contracts. The agency said each category must include detailed terms, settlement methods, data sources and compliance analysis. On the corporate and security side, WEMIX said a related contract’s ownership had been compromised, leading to the unauthorized minting of more than 5.22 million WEMIX, while BitMart’s publicly visible on-chain reserves fell sharply in the days before its shutdown announcement. Token Unlocks data also showed major scheduled unlocks next week for SUI, EIGEN, FF, KMNO and ENA.
