WEMIX says attacker moved about $724,000 after contract breach

cointelegraphPublicado a 2026-07-27Actualizado a 2026-07-27

Resumen

WEMIX reported a security breach where an attacker gained control of a contract linked to its WEMIX$ stablecoin, issuing approximately 5.23 million unauthorized tokens. These were converted into 30,736 WEMIX and 724,198.27 USDC.e. The attacker bridged the USDC.e to Ethereum and BNB Smart Chain, swapping for assets like Ether and USDT, and distributed them across multiple addresses, with some funds deposited into centralized exchanges. WEMIX has identified the attacker's wallets, requested freezes from exchanges and issuers, and confirmed some addresses have been frozen. In response, the company temporarily suspended all bridges to its WEMIX3.0 network, affected liquidity pool trading, and services like the WEMIX$ Module and PNIX DEX. The cause, full impact, and final figures are under investigation.

Layer-1 blockchain network WEMIX said an attacker moved about 724,000 in USDC.e tokens after compromising ownership of a contract linked to its WEMIX$ stablecoin and issuing tokens without authorization.

The abnormal transactions occurred on Sunday at 9:17 UTC, according to a preliminary incident update from WEMIX. The attacker issued about 5.23 million WEMIX$, which was converted into 30,736 WEMIX and 724,198.27 USDC.e. The USDC.e was then bridged to Ethereum and BNB Smart Chain before being exchanged for assets including Ether and Tether’s USDT and distributed across multiple addresses.

WEMIX said some of the funds were deposited into centralized exchanges. The company identified the attacker’s wallets and requested asset freezes and assistance from exchanges and stablecoin issuers, adding that some exchanges had already frozen addresses linked to the incident.

The company temporarily suspended all bridges connected to its layer-1 network, WEMIX3.0, including Chainlink CCIP and the PLAY Bridge. It also suspended trading in affected liquidity pools, withdrew foundation-provided liquidity, and paused services including the WEMIX$ Module and PNIX decentralized exchange.

WEMIX said the cause and full impact remain under investigation and warned that the preliminary figures could change.

Cointelegraph contacted WEMIX for additional information but did not receive an immediate response.

Breaking! OpenAI's Next-Gen AI Solves 10 Fields Medal-Level Problems

OpenAI's next-generation AI model Astra achieves breakthroughs in 10 long-standing mathematical conjectures. The results, including constructing the first known infinite, finitely presented non-sofic group—resolving a major question since 1999—and advancing the high-dimensional sphere packing problem beyond a 46-year-old barrier, are detailed in a 249-page paper. Key proofs have been formally verified using Lean 4. The AI also refuted a rigidity conjecture by Fields Medalist Alain Connes. According to OpenAI, generating these proofs cost under $2,000. Experts describe the findings as potentially Fields Medal-worthy and a landmark moment for both mathematics and AI, showcasing the model's ability to produce profound, human-like reasoning across diverse fields like group theory, geometry, and operator algebras.

How to Make Yourself Irreplaceable by AI Forever

This article argues that the primary threat from AI is not job replacement, but remaining trapped in "wage slavery"—financial dependence on employers. The path to becoming irreplaceable is not resisting AI, but becoming an "unemployable" individual who builds their own meaningful enterprise. The author identifies five key elements for this: Agency (acting without permission), Taste (judging what's worthwhile), Persuasion, Persistence, and Iteration. The solution is to stop being a "pawn" in someone else's game. To start, you must fundamentally change your identity and environment, then engage in rapid, real-world trial and error. While both coding and creating media (content) are powerful, content is more crucial. AI can generate assets, but true value lies in subjective, human-driven content that builds trust and narrative. The actionable advice is to carve out 15 minutes to answer foundational questions: 1) Uncover your "raw material"—what you know deeply or solve effortlessly. 2) Define your contrarian perspective—what common beliefs you think are wrong. The intersection of these answers is your direction. Finally, you must launch by publishing your first core idea immediately, using the feedback to iterate and develop the skills needed for a self-directed life and career.

Thanks to Dice Rolls, Bitcoin Keys Are Stored Offline, But Not Everyone Will Do It

The article discusses using dice rolls to generate secure Bitcoin wallet seeds, providing entropy independent of potentially flawed hardware random number generators. It explains that each fair dice roll offers about 2.585 bits of entropy, with around 50 rolls needed for a standard 12-word seed phrase and 99+ recommended for higher security. This method gained attention after a vulnerability was revealed in some Coldcard hardware wallets, where a faulty firmware RNG (dating back to 2021) compromised generated keys. The analysis notes that while a dice-generated main seed was safe from this specific flaw, other Coldcard functions (like creating paper wallets, backup keys, or passwords) could still be vulnerable if they used the defective RNG. The piece argues that while dice-based entropy is technically robust, the manual process is error-prone, tedious, and unrealistic for most new users, who might make mistakes in recording or inputting rolls. It concludes that while manual entropy generation should remain an option for advanced users, the long-term goal is to develop reliable, user-friendly hardware and software that securely generates randomness without requiring specialized knowledge. Coldcard users are advised to check their firmware version and replace any secondary secrets (like paper wallet keys) created with vulnerable devices, while also considering multi-signature setups with devices from different manufacturers for added security.

Michael Saylor Says It Has Become Impossible to Adopt the Bitcoin Update He Opposed!

Michael Saylor stated that it has become mathematically impossible for BIP-110 to achieve the 55% voluntary support threshold within the current Bitcoin mining difficulty adjustment cycle. Based on his analysis of 946 blocks generated up to block 960,561, only 24 blocks contained version field signals supporting BIP-110. Saylor claims all these signals came from DATUM miners sharing rewards via the OCEAN mining pool, with no supporting signals from non-OCEAN miners. He argues this situation prevents BIP-110 from reaching the required consensus level and that the current signals do not represent broad miner agreement. BIP-110 is a proposal aimed at making it more difficult to embed large data like images or text into the Bitcoin network, beyond simple monetary transactions. Its proponents argue Bitcoin should be used primarily for sending money to avoid network congestion. Saylor opposes this, believing the Bitcoin network should not dictate which transactions are necessary and that rules shouldn't change based on the preferences of a few. He also suggests that high support metrics may be inflated by automated signaling software rather than reflecting genuine miner consensus.

Number of Negative Bitcoin Comments Hits Record High: What Does This Mean?

Cryptocurrency analytics firm Santiment reported that negative sentiment toward Bitcoin on social media has reached a historically high level. The ratio of positive to negative comments about Bitcoin on platforms like X, Reddit, and Telegram has fallen to its lowest point since the firm began using its modern social monitoring system. A key driver of this sentiment is a vulnerability discovered in the firmware of Coldcard hardware wallets, shaking investor confidence in personal storage and cold wallets—previously considered the safest method for securing crypto assets. Santiment noted that while past crises like the collapses of FTX and Mt. Gox were larger in scale, the Coldcard incident uniquely shifted discussions toward hardware security and cold storage vulnerabilities, rather than centralized exchanges or leveraged trading platforms. Data shows only 0.58 positive comments for every negative one, indicating fear has significantly outweighed greed. Although the data covers just one day, Santiment stated the current panic level exceeds peaks seen earlier this year regarding war concerns and surpasses social media panic recorded during previous major crypto crises.
