加密货币安全取决于用户如何管理其私钥，设备和钱包

尽管区块链本身很难黑客攻击，但攻击者通过弱密码，不安全的网络和网络钓鱼骗局来针对用户。

Cryptocurrency security depends largely on how users manage their private keys, devices, and wallets. While the blockchain itself is nearly impossible to hack, attackers target users through weak passwords, unsafe networks, and phishing scams.

加密货币安全性在很大程度上取决于用户如何管理其私钥，设备和钱包。尽管区块链本身几乎不可能黑客入侵，但攻击者通过弱密码，不安全的网络和网络钓鱼骗局来针对用户。

The Bitcoin network has never been hacked. However, billions in crypto have been lost due to poor security practices. In 2011, Mt. Gox lost 850,000 BTC, worth around $450 million at the time. The breach did not affect Bitcoin’s code; it targeted a poorly secured exchange. Similar incidents hit Bitfinex (120,000 BTC), Bitfloor (24,000 BTC), and Binance (7,000 BTC). These attacks show that users and platforms remain vulnerable if the basics of cryptocurrency security are ignored.

比特币网络从未被黑客入侵。但是，由于安全行为不良，数十亿个加密货币丢失了。 2011年，Gox山损失了85万BTC，当时价值约4.5亿美元。违规行为不会影响比特币的代码；它针对的是安全不良的交换。类似的事件击中了Bitfinex（120,000 BTC），Bitfoor（24,000 BTC）和Binance（7,000 BTC）。这些攻击表明，如果忽略了加密货币安全的基础知识，则用户和平台仍然脆弱。

Complex Passwords Prevent Easy Access

复杂的密码阻止了轻松访问

Weak passwords allow attackers to access crypto wallets without much effort. Logs from breached platforms show the repeated use of “123456,” “123456789,” and “password.” These passwords appear in many hacking cases because they are predictable and easily cracked by automated tools that try these basic patterns first.

较弱的密码使攻击者无需太多努力即可访问加密钱包。违反平台的日志显示了“ 123456”，“ 123456789”和“密码”的重复使用。这些密码出现在许多黑客案例中，因为它们是可以预测的，并且可以通过自动化工具轻松破解，这些工具首先尝试这些基本模式。

Instead, users must build stronger password habits. A secure password always combines uppercase and lowercase letters, numbers, and special characters. The longer the password, the harder it is for software to guess. Each added character increases the time needed for a successful brute-force attack.

相反，用户必须建立更强的密码习惯。安全密码总是结合大写和小写字母，数字和特殊字符。密码越长，软件猜测越难。每个添加的角色都会增加成功的蛮力攻击所需的时间。

Password managers simplify this task. They generate random, complex passwords and save them in encrypted storage. This prevents users from reusing the same password across multiple platforms. Even if one account is compromised, others stay secure because the credentials remain unique.

密码管理人员简化了此任务。它们生成随机，复杂的密码，并将其保存在加密的存储中。这样可以防止用户在多个平台上重复使用相同的密码。即使一个帐户被妥协，其他帐户也保持安全，因为凭据仍然是独一无二的。

At the same time, some users prefer writing passwords on paper. This method avoids internet exposure entirely. When stored in a safe location, offline records reduce the risk of keyloggers or phishing attacks. Cold storage of passwords works well for long-term crypto holders who access their accounts less frequently.

同时，一些用户更喜欢在纸上写密码。此方法完全避免了互联网的暴露。当存放在安全的位置时，离线记录会降低钥匙记录员或网络钓鱼攻击的风险。密码的冷存储对于长期加密持有人的访问频率较低的长期加密持有人效果很好。

Also, avoid storing passwords in browsers or text files, as these locations can be easily scanned by malware. Always use password tools that apply end-to-end encryption or keep written copies secured offline. By using complex passwords and storing them correctly, users block one of the easiest attack methods in cryptocurrency security.

另外，避免将密码存储在浏览器或文本文件中，因为恶意软件可以轻松扫描这些位置。始终使用应用端到端加密的密码工具或离线保存书面副本。通过使用复杂的密码并正确存储它们，用户可以阻止加密货币安全性最简单的攻击方法之一。

Avoid Crypto Transactions Over Public Wi-Fi

避免通过公共Wi-Fi进行加密交易

Public Wi-Fi networks pose serious risks to cryptocurrency security. Most of these networks do not use strong encryption. As a result, anyone connected to the same network can intercept data with simple software.

公共Wi-Fi网络对加密货币安全构成严重风险。这些网络中的大多数不使用强加密。结果，连接到同一网络的任何人都可以使用简单的软件拦截数据。

Attackers often scan public networks in places like airports, hotels, cafés, and shopping malls. They wait for users to access sensitive services, including crypto wallets or exchanges. Once connected, hackers can launch a man-in-the-middle attack. This allows them to capture login credentials, private keys, session cookies, and other sensitive information in real time.

攻击者经常在机场，酒店，咖啡馆和购物中心等地方扫描公共网络。他们等待用户访问敏感服务，包括加密钱包或交易所。连接后，黑客可以发起中间人的攻击。这使他们可以实时捕获登录凭据，私钥，会话cookie和其他敏感信息。

If users access their crypto accounts without proper encryption, attackers can take full control of the wallet. These attacks require no physical access to the device, only shared access to the same public network. In some cases, attackers set up fake Wi-Fi networks that look like the real ones—so-called “evil twin” hotspots. Users unknowingly connect to them, thinking they are using the official network. Once connected, every action is visible to the attacker—including password entry and transaction signing.

如果用户在没有适当加密的情况下访问其加密帐户，则攻击者可以完全控制钱包。这些攻击不需要对设备的物理访问，只需要共享对同一公共网络的访问。在某些情况下，攻击者建立了看起来像真实的Wi-Fi网络，这些网络是如此的“邪恶的双胞胎”热点。用户在不知不觉中与他们联系，认为他们正在使用官方网络。连接后，攻击者都可以看到每个动作 - 包括密码输入和交易签名。

To reduce exposure, avoid using crypto wallets, exchanges, or any financial applications over public Wi-Fi. Even if you trust the network, unknown devices may still compromise it. When access is unavoidable, a trusted Virtual Private Network (VPN) helps. It encrypts all internet traffic and hides it from others on the same network. Still, VPNs only reduce—not eliminate—the risk.

为了减少暴露量，请避免使用加密钱包，交易所或公共Wi-Fi的任何财务应用。即使您信任网络，未知设备仍可能会损害它。当不可避免地访问时，受信任的虚拟专用网络（VPN）会有所帮助。它加密所有互联网流量，并将其隐藏在同一网络上的其他流量中。尽管如此，VPN仅降低（而不是消除）风险。

For critical actions such as sending crypto or changing wallet settings, switch to mobile data or wait for a secure connection. Cryptocurrency security relies heavily on connection safety. Public Wi-Fi removes that safety layer, making it one of the most dangerous environments for handling digital assets.

对于关键操作，例如发送加密货币或更改钱包设置，请切换到移动数据或等待安全连接。加密货币安全性在很大程度上依赖连接安全性。公共Wi-Fi删除了该安全层，使其成为处理数字资产的最危险环境之一。

Phishing Scams Mimic Trusted Platforms

网络钓鱼骗局模仿值得信赖的平台

Phishing scams create fake websites that look like real ones. They use similar domain names or copy interface elements to trick users. When users enter their credentials, the fake platform stores them and forwards them to attackers.

网络钓鱼骗局创建的假网站看起来像真实的网站。他们使用类似的域名或复制接口元素来欺骗用户。当用户输入凭据时，假平台将它们存储并将其转发给攻击者。

MyEtherWallet experienced multiple phishing attacks. Fake sites with minor spelling errors (like “myetherwaIlet” using a capital i) redirected users. Once logged in, users unknowingly shared private keys with scammers.

MyetherWallet经历了多次网络钓鱼攻击。伪造的拼写错误的伪造网站（例如使用Capele I的“ MyetherWailet”）重定向用户。登录后，用户在不知不觉中与骗子共享私钥。

Bookmark exchange URLs to avoid visiting fake versions. Only open crypto wallets or exchanges from trusted sources. Avoid clicking login links from unknown emails or pop-ups. Always look for HTTPS and the padlock symbol in the browser bar before signing in.

为避免访问伪造版本的添加书签交换URL。仅开放加密钱包或可信赖的来源交换。避免单击未知电子邮件或弹出窗口中的登录链接。在签名之前，请务必在浏览器栏中查找HTTPS和挂锁符号。

Crypto Exchanges Are Not Safe Storage

加密交换不是安全的存储

Exchanges are designed for trading, not for long-term storage. Most major crypto hacks targeted exchanges—not the coins or blockchains. In 2016, hackers took 120

交易所设计用于交易，而不是用于长期存储。大多数主要的加密货币hacks针对交流，而不是硬币或区块链。在2016年，黑客服役120
