新報告顯示洗錢者可以通過利用凍結延遲來竊取多少錢

儘管區塊鏈調查人員在凍結非法資金時抱怨一些集中式交流和穩定發行人的反應緩慢，但一份新報告顯示了這一過程是如何工作的以及它已經成本的成本。由Samuele S.

Centralized exchanges and stablecoin issuers have been slow to respond to requests from blockchain investigators to freeze illicit funds, according to a new report by AMLBot.

根據Amlbot的一份新報告，集中式交流和Stablecoin發行人對區塊鏈調查人員的要求響應凍結非法資金的要求很慢。

The report, which was published on Monday, claims that a significant lag between the initiation of a freeze and its actual enforcement has already allowed the transfer of more than $78 million in the Tether (USDT) stablecoin on the Tron (TRX) and Ethereum (ETH) blockchains.

該報告於週一發表，聲稱凍結的啟動與其實際執行之間的滯後滯後已經允許在TRON（TRX）（TRX）和Ethereum（ETH）（ETH）區塊鏈中轉移超過7800萬美元的鏈球菌（USDT）Stablecoin。

According to AMLBot, criminals are already familiar with the freezing process and are exploiting it to launder money. They may even be developing new money laundering tools that can be used to automate the process during the freeze delay window.

根據Amlbot的說法，罪犯已經熟悉凍結過程，並將其利用為洗錢。他們甚至可能正在開發新的洗錢工具，這些工具可用於在凍結延遲窗口中自動化該過程。

In one specific case that was presented in the report, it took 44 minutes to freeze USDT on Tron after a suspicious address was flagged. However, during this period, the wallet still had full access to 426,183 USDT, which means that a fast-acting operator could have moved the funds before the freeze took effect.

在報告中提出的一個具體情況下，在標記可疑地址後，花了44分鐘才能在Tron上凍結USDT。但是，在此期間，該錢包仍然可以完全訪問426,183 USDT，這意味著快速效果的操作員可能會在凍結生效之前將資金移動。

“This isn’s a theoretical weakness. It’s impacting the real world and bad actors are watching,” AMLBot warned.

Amlbot警告說：“這是一個理論上的弱點。這會影響現實世界，而壞演員正在觀察。”

According to the crypto AML compliance solutions provider, the delay is likely due to Tether’s custom multi-signature smart contract on Tron, which requires more than one digital signature to confirm a transaction.

根據Crypto AML合規解決方案提供商的說法，延遲可能是由於Tether在TRON上的自定義多符號智能合約，該合約需要多個數字簽名來確認交易。

This was likely done to improve internal governance and reduce the risk of unilateral actions, but it also makes a freeze request visible on-chain, allowing criminals to react accordingly.

這可能是為了改善內部治理並降低單方面行動的風險，但它也使凍結請求可見鍊子，從而使罪犯能夠做出相應的反應。

A similar setup for USDT was also identified on Ethereum, with freezing delays of up to one hour, which allowed the withdrawal of at least $28.5 million in USDT on Ethereum.

在以太坊上也確定了類似的USDT設置，凍結延遲最多為一個小時，這使得在以太坊的USDT中至少撤出了至少2850萬美元。

“The average amount moved per wallet was over $365,000, which reaffirms that this isn’t a minor flaw—it’s a systemic issue across chains,” the report concluded, adding that, in the case of Tron, $49.6 million was withdrawn during freeze delay windows, with two-three transfers taking place on average.

該報告得出結論，“每個錢包的平均額定金額超過365,000美元，重申這不是一個小缺陷，這是跨連鎖店的系統問題。”報告總結說，對於Tron而言，在凍結延遲窗口期間撤回了4,960萬美元，平均進行了兩分之一的轉移。
