Munchables 遭遇内部攻击

今日凌晨 5 时,Blast 生态项目 Munchables 在 X 平台发文表示其遭到攻击。据派盾披露,Munchables 锁定合约疑似存在问题,导致 1.74 万枚 ETH(价值约 6230 万美元)被盗。

Munchables 是 Blast BIG BANG 竞赛冠军项目之一,是以 NFT 质押为载体的链游类项目。在协议发展初期,用户可通过质押 1 ETH 或等值代币来免费铸造 NFT,锁仓 30 天,并有额外激励机制来促使用户锁定更长时间。质押资产可获得 Blast 积分+黄金积分+协议治理代币等一系列权益。如 NFT 巨鲸 dingaling 曾公布其在该协议质押了 150 枚 ETH

目前该项目已完成 Pre-Seed 轮融资,Manifold 和 Mechanism Capital 共同领投,融资金额暂未披露。

又现朝鲜黑客身影

昨夜攻击事件发生后,链上安全侦探 ZachXBT 率先发声指出,攻击事件与朝鲜开发者相关,并发布了其简历

今晨,慢雾余弦就 Munchables 遭攻击一事在 X 平台发文表示:“Blast 上的这个协议 Munchables 被盗 6250 万美元,损失真大了。按链上侦探 ZachXBT 的调查,是因为他们的一位开发者是朝鲜黑客……这是我们遇到的至少第二起 DeFi 类项目遭遇的这类情况了。核心开发者伪装潜伏很久,获得整个 team 的信任,时机一到就下手了……。”

此后 Aavegotchi 创始人 CoderDan 于 X 平台发文表示:“Aavegotchi 的开发团队 Pixelcraft Studios 在 2022 年曾短期雇用过 Munchables 攻击者来进行一些游戏开发工作,他技术很糙,感觉确实像一名朝鲜黑客,我们在一个月内解雇了他。他还试图让我们雇用他的一位朋友,那个人很可能也是一名黑客。”CoderDan 补充表示,Pixelcraft Studios 当时和他进行过一些视频通话,但没有录频,不确定谷歌是否在内部记录了所有的视频通话,但那个黑客确实曾露过脸

最后,CoderDan 向 Munchables 团队提供了该黑客就职于 Pixelcraft Studios 时的常用地址,希望能通过这些线索帮助 Munchables 找回资金。

截止目前,还没有特别直接的证据证明黑客真实身份,但多方证词均透露了此次事件背后的朝鲜黑客身影。

为何出现安全事件?

据链上分析师@SomaXBT披露,Blast 生态被盗项目 Munchables 此前为节省审计费用,雇佣不知名安全团队 EntersoftTeam 出具审计报告。该团队的账号简介为“我们是一家屡获殊荣的应用程序安全公司,拥有经过认证的白帽黑客”,但平台仅百余名关注者。

最新消息,经 ZachXBT 分析,Munchables 团队雇佣的四个不同的开发人员可能都是同一个人,他们互相推荐对方做这份工作,并定期转账到相同的两个交易所存款地址,还为彼此的钱包充值。

攻击者突然良心发现?

下午 14 时,据链上数据分析平台Scopescan 监测,Munchables 攻击者向某多签钱包0x 4 D 2 F 退还了所有的 1.7 万枚 ETH,彼时尚不确定是否为攻击者退款或者转移地址。

半小时后,Blast 创始人 Pacman 于 X 平台公告,Blast 核心贡献者已通过多重签名获得 9700 万美元的资金(分别为被盗的 1.74 万枚 ETH 和协议内剩余未被取走的 9450 枚 wETH,目前价值 9600 万美元)。感谢前 Munchables 开发者选择最终退还所有资金,且不需要任何赎金。Munchables 也转发此公告表示:“所有用户资金都是安全的,不会强制执行锁定,所有与 Blast 相关的奖励也将被分配。未来几天将进行更新。”

同时此前同步受到 Munchables 攻击事件影响的 Juice 也宣布了资金的安全,其所有的 wETH 均已从 Munchables 开发者手中取回,Jucie 正在与 Pacman 和 Blast 协调将 wETH 转移回 Juice,以便用户能够提款。

攻击者为何突然良心发现退款,背后的故事我们不得而知,昨夜其曾通过第三方跨链桥 Orbiter 进行了一笔跨链洗币,但金额仅 3 ETH。通过官方跨链桥需要 14 天转移时间,而第三方跨链桥流动性不足,或许最终难以有效转移资金促成了其协商退款。

结论

历来各新链初始上线时,由于团队良莠不齐、基础设施不全,项目卷款跑路或受黑客攻击事件屡见不鲜,早期团队对成员缺乏被背调、监守自盗的事件也时有发生,不能每次都指望攻击者摇身一变成为白帽“良心发现”退款,建议投资者 DYOR 并严格控制投资仓位配比。

18 Months, Over 50x Surge: KIOXIA's Epic Comeback

KIOXIA, a NAND flash memory giant, staged a dramatic comeback driven by AI demand. After a period of significant losses, a failed merger, and missed HBM opportunities, its 2024 IPO began modestly. However, fueled by explosive demand for AI data storage, its stock price skyrocketed over 50 times within 18 months, making it Japan's most valuable company, surpassing Toyota. Its Q1 FY2026 profit guidance soared 30-fold year-over-year, with 2026 NAND capacity already sold out. Key to its success is its 3D NAND technology, BiCS FLASH. As the inventor of NAND, KIOXIA advanced its technology through generations, reaching over 200 layers by 2023. Key innovations include CBA (CMOS directly Bonded to Array), which separately manufactures control circuits and memory arrays for better performance, and OPS (On Pitch Select Gate) to increase density. The company is now developing high-capacity packages like an 8TB solution stacking 32 dies. Looking beyond NAND, KIOXIA is exploring 3D DRAM with its OCTRAM technology, using oxide semiconductor transistors for ultra-low leakage to reduce power consumption. This fundamental research differs from HBM and represents a long-term bet to extend its 3D expertise from NAND into future DRAM architectures. KIOXIA's story highlights how technological assets and shifting market cycles can rapidly transform a company's fortunes. While questions remain about sustaining growth beyond the current AI boom, its resurgence demonstrates that in semiconductors, being down does not necessarily mean being out.

Market Trends in U.S. Stocks (June 23): Peak at Listing? SpaceX Loses Over $800 Billion in Three Days, Tech Stocks Experience Severe Internal Divergence

Stock Market Trends (June 23): Did SpaceX Peak at IPO? The company loses over $800 billion in market value in three days as a sharp divergence unfolds within the tech sector. SpaceX's post-IPO decline of over 20%, falling below its first-day close, reflects a swift market repricing. The catalyst is a clear shift in narrative from "AI platform potential" to concerns over rising capital costs, as its $8.57 billion IPO and subsequent $20 billion debt offering are earmarked for acquisitions and refinancing existing bridge loans rather than de-leveraging. While high-valuation tech stocks like Google, Meta, Amazon, and Microsoft faced pressure, Micron surged nearly 7% to a record high following a strategic supply deal with Anthropic for HBM and memory, highlighting robust, tangible demand in AI infrastructure. The broader market saw funds rotate into more defensive industrial and financial names. Macro factors included a dip in oil prices to a three-month low on news of a US-Iran framework deal, though logistical hurdles for resuming full Strait of Hormuz shipments remain. Key events ahead include Nvidia's shareholder meeting, Micron's earnings, and the May PCE inflation data. The latter will be crucial in determining whether the sell-off in high-valuation growth stocks, which appears to have just begun, will persist.

Interview with MicroStrategy CEO: Beyond the 32 BTC Selling Stir, 6 Trillion AI Agents are the Ultimate Endgame for Bitcoin

Interview with Strategy CEO: Beyond the 32 BTC Sale, 6 Trillion AI Agents are Bitcoin's Ultimate Endgame Strategy CEO Phong Le discusses the recent sale of 32 BTC, clarifying it was a minor, strategic move to demonstrate operational liquidity and internal process robustness to creditors and rating agencies, not a reaction to market fears. He emphasizes Strategy's disciplined, data-driven decision-making framework involving its board and complex financial modeling, distancing the company from centralized "black box" operations seen elsewhere in crypto. Le outlines the company's resilience and long-term focus, citing the "doing nothing" strategy during the 2022 bear market as a testament to its conviction in Bitcoin's underlying value proposition for global sovereignty and freedom. He reveals that generative AI was instrumental in developing their Stretch (STRC) preferred stock product, cutting development time from years to months. The most visionary part of the discussion centers on Agentic AI. Le envisions a future with 6 trillion autonomous AI agents conducting commerce, particularly in off-world environments like Mars, which would naturally adopt decentralized crypto rails and seek yield-bearing assets like Bitcoin as a core store of value. Finally, Le addresses the STRC product, expressing confidence it will return to its $100 par value through reserve replenishment and the initiation of dividend payments, and dismisses concerns about competition with stablecoins. He concludes by affirming Strategy's philosophy of expanding Bitcoin access through all available means, from self-custody to ETFs, to onboard the next wave of users.
