除尘攻击：它们是如何工作的以及如何避免它们

这些交易金额很小，甚至可能不会被钱包所有者注意到。通过监控和分析交易

These transactions are usually for such small amounts that they may even go unnoticed by the owner of the wallet. However, by meticulously monitoring and analyzing these transactions, it is possible to ascertain the identity of the wallet owner. The primary goal of this type of attack is to ultimately steal from the end user.

这些交易通常金额很小，甚至可能不会被钱包所有者注意到。然而，通过仔细监控和分析这些交易，可以确定钱包所有者的身份。此类攻击的主要目标是最终从最终用户那里窃取信息。

The term “dust” refers to the minimal quantity of cryptocurrency that typically remains as residue following a transaction between two wallets. Each blockchain (or rather, each cryptocurrency) sets its own minimum.

“灰尘”一词是指两个钱包之间交易后通常残留的最少量的加密货币。每个区块链（或者更确切地说，每个加密货币）都设置自己的最小值。

For the Bitcoin blockchain, the “dust” limit on this network is 547 satoshi (0.00000547 BTC). To put this in perspective, at the current exchange rate, this equates to approximately 0.35 euros, which is hardly a substantial amount. Yet, if the price of Bitcoin were to rise significantly, this limit may no longer be sufficient to even cover the cost of a coffee.

对于比特币区块链，该网络上的“灰尘”限制为 547 聪（0.00000547 BTC）。从目前的汇率来看，这大约相当于 0.35 欧元，这并不是一个很大的数字。然而，如果比特币的价格大幅上涨，这一限制可能甚至不足以支付一杯咖啡的成本。

Returning to the matter at hand, transactions with negligible value generate a sort of digital footprint. These days, malicious attackers are undertaking fetching tasks to extract account information. Through these transactions, attackers are able to obtain data from the targeted wallet. Subsequently, they cross-check this data with other techniques, such as web scraping, in an attempt to uncover the user’s identity.

回到当前的问题，价值可以忽略不计的交易会产生一种数字足迹。如今，恶意攻击者正在执行获取任务以提取帐户信息。通过这些交易，攻击者能够从目标钱包获取数据。随后，他们使用其他技术（例如网络抓取）交叉检查这些数据，试图揭示用户的身份。

Evading these attacks may seem like a daunting task, given that they involve a combination of transaction advertising and residual information about transactions. Nevertheless, it is important to be aware of a series of actions that can help prevent falling victim to scams or extortion as a result of these attacks. These actions include:

躲避这些攻击似乎是一项艰巨的任务，因为它们涉及交易广告和交易残留信息的组合。尽管如此，重要的是要了解一系列有助于防止因这些攻击而成为诈骗或勒索受害者的行动。这些行动包括：
