除塵攻擊：它們是如何運作的以及如何避免它們

這些交易金額很小，甚至可能不會被錢包所有者註意到。透過監控和分析交易

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.

這些交易通常金額很小，甚至可能不會被錢包所有者註意到。然而，透過仔細監控和分析這些交易，可以確定錢包所有者的身份。此類攻擊的主要目標是最終從最終用戶那裡竊取資訊。

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.

「灰塵」一詞是指兩個錢包之間交易後通常殘留的最少量的加密貨幣。每個區塊鏈（或更確切地說，每個加密貨幣）都設定自己的最小值。

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.

對於比特幣區塊鏈，該網路上的「灰塵」限制為 547 聰（0.00000547 BTC）。從目前的匯率來看，這大約相當於 0.35 歐元，這並不是一個很大的數字。然而，如果比特幣的價格大幅上漲，這一限額可能甚至不足以支付一杯咖啡的費用。

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.

回到當前的問題，價值可以忽略不計的交易會產生一種數位足跡。如今，惡意攻擊者正在執行獲取任務以提取帳戶資訊。透過這些交易，攻擊者能夠從目標錢包獲取數據。隨後，他們使用其他技術（例如網頁抓取）交叉檢查這些數據，試圖揭示用戶的身份。

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:

躲避這些攻擊似乎是一項艱鉅的任務，因為它們涉及交易廣告和交易殘留資訊的組合。儘管如此，重要的是要了解一系列有助於防止因這些攻擊而成為詐騙或勒索受害者的行動。這些行動包括：
