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。

a16z Deep Dive: Stop Chasing the 'AI Smell', Here's a Practical Guide to Writing with AI

"Don't Obsess Over AI Detection: A Practical Guide to Writing Alongside AI" by Steph Zinn (a16z Crypto) This guide moves beyond the flawed premise that AI-generated text can be easily spotted by a set of "tells" and that these features automatically mean poor quality. Instead, it focuses on how writers and founders can use LLMs effectively by understanding, controlling, and editing the common stylistic tendencies of AI-assisted prose. The article breaks down AI writing "tells" into four key dimensions: **1. Rhetorical Features (Insight-Shaped Writing):** AI often produces semantically empty, "corporate-sounding" filler language—vague profundities, hedging phrases, excessive parallelism, and summary statements. The advice is to ruthlessly edit these out, using prompts to make language more specific and direct. **2. Voice Features (The Alexa Voice):** Default AI writing relies on a narrow, fungible vocabulary of low-friction, abstract words and cliché phrases that lack personality. While this generic voice is acceptable for support docs or mass communications, founders should preserve their unique voice for impactful writing. Use LLMs to identify and replace jargon, aiming for concrete, distinctive word choices. **3. Structural Features (Form Without Function):** AI tends towards over-structured text with excessive subheadings, lists, roadmaps, and the rigid "three-point" framework. While clear structure is good for readability and SEO, it shouldn't force ideas into unnatural containers. Choose a structure that serves the format and purpose, borrowing from effective examples. **4. Punctuation Features (Dash Panic):** The overuse of em dashes and colons has become a hallmark, but writers shouldn't avoid useful punctuation just to seem "human." The key is avoiding repetitive, distracting patterns. Use punctuation that is grammatically correct and supports the flow of your argument. The core argument is that many so-called AI flaws are just amplified versions of existing bad writing habits. The goal isn't to eliminate AI's role but to use it as a tool while maintaining editorial control. The final question shouldn't be "Can this be detected as AI?" but "Does this writing effectively do its job?"

Podcast Notes | Conversation with Tom Lee: Bitmine Acquiring Nearly 5% of Total ETH Supply Is Not the End Goal, ETH Price Target Set at $10,000

In a podcast interview, Tom Lee, Chairman of BitMine Immersion Technologies, discusses the company's strategy to accumulate nearly 5% of the total Ethereum supply within 14 months, using equity financing and avoiding debt. BitMine has consistently purchased ETH for over 60 consecutive weeks, with recent weeks combining buybacks with purchases. The company's substantial ETH holdings generate approximately $300 million in annual staking rewards, covering operational costs like the dividends for its 9.5% perpetual preferred stock (BMNP). Lee positions ETH as a store-of-value asset, likening it to stocks or land, rather than a pure cash-flow instrument. Looking ahead, Lee suggests BitMine may continue buying beyond the 5% target if institutional adoption grows. He outlines a bullish price target for ETH: surpassing $5,000 in a new crypto bull cycle and potentially exceeding $10,000 within 1-2 years, driven by Wall Street tokenization and AI-related demand. The discussion also covers BitMine's evolution into an ecosystem player, funding Ethereum Foundation spin-offs and developing its Maven staking platform. Lee acknowledges his significant financial interests are tied to ETH's price and BitMine's performance. The interview provides a framework for evaluating ETH as a long-term asset, emphasizing staking yield sustainability and future institutional demand, while noting the uncertainties surrounding macro cycles and real-world adoption.

Pricing Risk Assets in 8 Hours: Tonight's PCE to Set the Discount Rate, Nvidia to Test Earnings Tomorrow Morning

"Pricing Risk Assets in 8 Hours: PCE to Set the Discount Rate Tonight, NVIDIA to Test Profits Tomorrow Morning" Risk asset prices hinge on two variables: the numerator (earnings expectations) and the denominator (the discount rate). Both will be recalibrated within eight hours. First, at 20:30 Beijing time, the US Bureau of Economic Analysis releases July PCE inflation data and the second estimate of Q2 GDP. Consensus expects mild core PCE growth, but a surge in key PPI components poses an upside risk. A hotter-than-expected print could push Treasury yields and the dollar higher, threatening the recent rally in Bitcoin (BTC) above $80K, which was fueled by falling yields. A benign reading would support risk assets. Market sentiment is already "greedy" (Fear & Greed Index at 74), making it vulnerable to disappointment. Second, around 04:20, NVIDIA reports its Q2 FY27 earnings. While consensus revenue of ~$91.85B slightly exceeds company guidance, the market has priced in a beat. The key will be the magnitude of the beat and, crucially, the Q3 guidance. As a bellwether for tech and AI narratives, NVIDIA's results will significantly impact overall risk appetite and AI-related crypto tokens. The combination creates four scenarios: 1) Benign PCE & strong NVIDIA guidance confirms the bullish trend. 2) Hot PCE & strong NVIDIA leads to conflicted signals and likely volatility for BTC. 3) Benign PCE & weak NVIDIA guidance pressures tech but offers some macro support for BTC. 4) Hot PCE & weak NVIDIA guidance presents a "double whammy," risking a sharp pullback in BTC toward the $75K-$76K support zone. The outcomes will set the tone for markets ahead of the upcoming Jackson Hole symposium.
