涉及7400万美元 一家已倒闭的香港交易所 Atom Asset (AAX) 逃避反洗钱(AML)分析

金色财经Published on 2024-07-08Last updated on 2024-07-08

近期,一家已倒闭的香港交易所 Atom Asset (AAX) 开始将资金从其钱包转移到各种去中心化交易所和中心化平台,据称是为了逃避反洗钱(AML)控制。

在被发现之前,最后一次已知的涉及 AAX 交易所钱包的交易发生在 2023 年 10 月和 2022 年 11 月。在倒闭之前,AAX 是香港最大的加密货币交易所之一,拥有超过 200 万用户。

根据Beosin团队的分析,发现自2024年1月29日起,AAX交易所开始将25100枚ETH从其交易所钱包向外转移,其中转移资金共分了三笔,分别是一笔500ETH、一笔600ETH、一笔24000ETH。转移资金根据当前价格换算超7400万美元。究竟是怎么回事,这家交易所还有哪些不可告知的链上数据蹊跷,请和我们继续往下看。

AAX交易所事件来龙去脉

2022 年 11 月 13 日,就在加密货币交易所 FTX 申请破产后两天,AAX 也因交易对手风险暴露而停止提款并清除了所有社交渠道。最初,AAX 将冻结归因于针对涉嫌恶意攻击的安全措施。

2022年11月15日,AAX交易所发布声明表示其平台需要进行维护,除暂停提现外,将对衍生品进行自动清算。此后,AAX停止了平台运行和社交媒体的更新。

而蹊跷的事就在于:沉寂426天后,AAX交易所钱包开始活动,开始有大额资金开始转出至其它地址,尝试躲避AML工具的识别和监控!

AAX交易所事件链上资金分析

Beosin KYT反洗钱分析平台对AAX交易所钱包近期的链上活动进行了深入研究,发现了一系列风险活动。首先,所有的25100枚ETH已被转移,操作人员采取了各种手段将部分ETH兑换为USDT,然后通过Cross Bridge跨链桥将资金转移到不同的区块链上,以进行资金的清洗。

其中,大部分资金被转移到了Tron区块链上,并通过一些地址进行中转,然后沉淀在某些地址中,未曾转移。这种行为表明了明显的逃避AML的企图,试图掩盖资金的真实来源和去向。

香港警方针对诈骗活动迅速采取行动,逮捕了两名与AAX相关的人员,目前正在努力绘制转移资金的路径并找回受影响用户的资产。

AAX交易所利用去中心化交易所、加密货币兑换和跨链桥等技术手段,试图模糊资金流动的路径和来源。这为监管机构和AML分析平台带来了巨大的挑战。

如何解决加密货币洗钱难题?

由于加密资产的匿名性、便利性和去中心化特性,不法分子会选择使用加密资产转移其非法获利的资金,监管机构与虚拟资产服务提供商(诸如加密货币交易所、加密钱包提供商、加密资产支付处理商等)面临着反洗钱及反恐怖融资等挑战

对于监管机构而言,相关部门应完善和执行监管政策,确保虚拟资产服务提供商遵守AML和KYC规定,同时加强与各国家和地区监管机构的合作,共同打击跨境洗钱活动。

对于虚拟资产服务提供商而言,以下是防范非法资金的有效措施:

1.  实施严格的KYC和AML规定

交易所应该要求用户进行全面的身份验证,并确保他们符合KYC和AML规定。这包括收集用户的身份信息、地址验证和其它必要的资料。

2.  监控交易活动

虚拟资产服务提供商应该实施实时监控系统,以便检测和分析可疑交易活动。这包括监控交易金额、频率、来源和目的地等信息。交易所可利用 Beosin KYT 对每一笔交易进行定位,对用户进行画像,对交易进行评级,识别链上犯罪行为,从而降低犯罪者利用虚拟资产洗钱的风险。

3.  设立报告机制

虚拟资产服务提供商应建立报告机制,通过风控系统报告任何可疑交易或活动。虚拟资产服务提供商应及时处理这些报告,并与监管机构合作进行调查。Beosin KYT 可为虚拟资产服务提供商出具可疑交易报告(STR),帮助监管机构和执法机构进行取证调查。

4.  加强合作与交流

虚拟资产服务提供商应积极与安全公司、监管机构和执法机构合作,共同打击洗钱活动。可以预见,犯罪分子会不断调整和改进其洗钱策略,以适应监管措施和AML工具的变化。他们可能采取分散化的交易方式、使用隐蔽的交易路径或利用技术漏洞来隐藏非法资金流动。虚拟资产服务提供商应定期与安全公司进行合作交流,及时识别和应对这些变化。

Beosin注重KYT反洗钱工具的持续更新和优化,我们不断监测行业动态和新的安全威胁,将最新的分析成果和数据应用于Beosin KYT工具的改进中。这种持续的更新和优化确保了 Beosin KYT 在面对不断变化的恶意洗钱行为时能保持高度的敏感性和准确性。

总结

AAX交易所事件再次凸显了反洗钱的重要性。为了更好地应对类似事件,监管机构需要与虚拟资产服务提供商、区块链安全合规公司加强合作,共享信息和最佳实践,引入先进的反洗钱分析工具和平台,如 Beosin KYT 反洗钱分析平台,以加强对链上资金流动的监测和分析能力。

Podcast Notes: Hyperliquid Has Become the Top Interest Point for Traditional Hedge Funds

Empire Podcast hosts Jason Yanowitz and Santiago Santos discuss the surging institutional interest in Hyperliquid, a decentralized perpetual exchange, marking the highest level of engagement from traditional hedge fund managers since Paul Tudor Jones endorsed Bitcoin in 2020. The primary driver is the demand for weekend trading of commodities like oil, especially during geopolitical tensions such as the Iran conflict, as Hyperliquid provides the only active price discovery venue when traditional markets are closed. Trade XYZ, a front-end on Hyperliquid, has seen significant growth, with weekend oil price predictions having a median error of only 50 basis points. Santos predicts commodity trading volume on Hyperliquid will surpass Bitcoin within the year and that its market cap could rise from $25 billion to $100 billion. Other key points include Kraken raising $200 million at a reduced valuation of $13.3 billion, and the SEC clarifying that self-custodied DeFi frontends like MetaMask are not subject to broker-dealer rules, resolving a major regulatory uncertainty. The hosts also note the strong correlation between crypto and macro markets, with the S&P 500 posting one of its best 10-day rallies since 1950. They highlight MicroStrategy's continued Bitcoin acquisitions and the potential of real-world asset (RWA) tokenization as a key trend. The discussion concludes with skepticism towards many L2 projects, predicting a wave of protocols truly going to zero as capital concentrates in proven assets like Bitcoin and Hyperliquid.

a16z: The Next Frontier of AI, The Triple Flywheel of Robotics, Autonomous Science, and Brain-Computer Interfaces

a16z presents a comprehensive investment thesis for the next frontier of AI: Physical AI, centered on a synergistic flywheel of robotics, autonomous science, and novel human-computer interfaces (HCIs) like brain-computers. While the current AI paradigm scales on language and code, the most disruptive future capabilities will emerge from three adjacent fields leveraging five core technical primitives: 1) learned representations of physical dynamics (via models like VLA, WAM, and native embodied models), 2) embodied action architectures (e.g., dual-system designs, diffusion-based motion generation, and RL fine-tuning like RECAP), 3) simulation and synthetic data as scaling infrastructure, 4) expanded sensory channels (touch, neural signals, silent speech, olfaction), and 5) closed-loop agent systems for long-horizon tasks. These primitives converge to power three key domains: * **Robotics:** The literal embodiment of AI, requiring all primitives for real-world physical interaction and manipulation. * **Autonomous Science:** Self-driving labs that conduct hypothesis-experiment-analysis loops, generating structured, causally-grounded data to improve physical AI models. * **Novel HCIs:** Devices (AR glasses, EMG wearables, BCIs) that expand human-AI bandwidth and act as massive data-collection networks for real-world human experience. These domains form a mutually reinforcing flywheel: Robotics enable autonomous labs, which in turn generate valuable data for robotics and materials science. New interfaces provide rich human-physical interaction data to train better robots and scientists. Together, they represent a new scaling axis for AI, moving beyond the digital realm to interact with and learn from physical reality, promising significant emergent capabilities and value.

Conversation with Bitwise Advisor: From K-Shaped Economy to AI Taking Jobs, How Can Bitcoin Save the Younger Generation?

Jeff Park, a macro strategist and advisor at Bitwise, argues that the traditional financial system is broken, particularly for young generations. He describes a "K-shaped economy" where asset inflation enriches the wealthy while leaving others behind, with unaffordable housing as a key symptom. Park explains that real estate is often a depreciating asset due to maintenance costs and taxes, yet it remains unattainable for many young people due to distorted demand from global capital flows. He proposes Bitcoin as a superior store of value—scarce, portable, and free from maintenance costs or excessive taxation. By diverting capital away from real estate, Bitcoin could help lower housing prices and increase accessibility. Park also discusses the decline of traditional "smart investing" (e.g., value stocks) and the rise of "ideological investing" in non-correlated assets like crypto, luxury goods, and collectibles. On AI, Park warns it could trigger extreme social inequality by eliminating jobs while boosting corporate profits. He believes this will push younger generations toward Bitcoin, not only as a hedge but also as a symbol of decentralization and data sovereignty—offering an alternative to centralized AI systems that use personal data without fair compensation. He advises a diversified portfolio with Bitcoin as a core holding to hedge against currency devaluation and systemic risk.
