在Crypto世界里，利用协议漏洞和网络钓鱼成为了加密黑客们发起攻击的主要方式。据相关报道称，在2022年第2季度，加密行业因协议漏洞损失的总金额超过6.7亿美元，同比去年增加了近 50%。正是由于加密行业的代码公开透明，黑客可以通过查看目标代码，致力于发现漏洞并发起攻击。因此不少Web3项目专门通过推出漏洞赏金计划，来避免更大的经济损失。而自5月以来，钓鱼网络攻击更是屡见不鲜。如通过Discord私信诈骗网站链接、发送钓鱼邮件（Opensea钓鱼邮件）以及伪装代币空投发送恶意链接（Uniswap V3被盗）等，让毫无戒备的用户防不胜防。其中以太坊生态系统成为了主要受害者，而随着NFT的增量发展，近期加密黑客们又开始了NFT“钓鱼”，不少NFT资产频频被盗。常见的两种NFT钓鱼攻击方式为盗取用户签名以及高仿域名和内容的NFT钓鱼网站。如何监控和保护加密资产安全成为了重中之重。一旦遭到黑客攻击，项目方采取何种措施保护客户资产安全，以及普通用户如何监控其关心的地址和交易详情，是在Web3时代关心的重点问题。因此这就体现了区块链API技术的重要性。API的价值在于可以提供安全性、隐私性以及易用性的数据服务。目前API应用于加密行业的各个领域，涉及代币交易、地址监控以及交易分析和安全。如区块链API提供商Tokenview就为区块链行业开发者和普通用户提供地址监控和数据API，帮助用户及时获得链上数据的变化，监控地址的交易动态。接下来，Tokenview教你如何利用API监控黑客地址。一、获取黑客地址以Uniswap V3被盗事件为例：2022年7月12日，Binance首席执行官CZ发推提醒，黑客在Uniswap V3平台上窃取了4,295枚ETH。Uniswap 创始人 Hayden Adams也证实此次失窃是一种钓鱼网络攻击。一些LP NFT会因为误点授权交易而被窃取。我们可以通过监控地址和链上转账行为获取更多信息。具体被盗过程请参见：警惕！又一起网络钓鱼攻击事件：Uniswap被盗810万美元。我们通过Tokenview区块链浏览器找到该黑客地址（Fake_Phishing5875）：https://eth.tokenview.com/cn/address/0x09b5027ef3a3b7332ee90321e558bad9c4447afa
二、为什么要监控黑客地址由于区块链的匿名性，我们无法获取黑客的真实身份信息。如果黑客将盗取的资金转入如Binance 中心化交易所，也许就能获取黑客的蛛丝马迹。当然，这种想法往往过于直接，黑客既然选择转入交易所账户，必然会考虑到自身信息的匿名性。监控黑客地址的另一个原因是为了及时获取黑客的动态，一旦黑客地址有异动，可以将黑客相关联的地址都监控起来，以防黑客会进行下一场骗局或其它行动。从盗得资金到下一步行动，整个过程可能会持续半年甚至更长的时间。这也给我们的监测带来很多困难。这时候如果通过某个程序或者API，在地址余额变动的时候第一时间获取相关信息，那么监测就会变得容易很多。三、如何监控黑客地址Tokenview 的监控地址 API 通过 Webhook 的方式，将地址余额变动信息 POST 到设置的 Webhook URL 上。使用Tokenview 地址监控 API 来追踪黑客地址一般需要以下三个步骤：
注册Tokenview开发者账号：https://services.tokenview.com 设置地址监控 Webhook URL 输入或复制「黑客地址」
完成上述步骤后，一旦黑客地址发生交易信息，将会第一时间收到通知，掌握黑客地址的实时动态。最后，Tokenview提醒您要学会的【防骗技巧】：1 防范签名被盗，签署交易时需确认交易内容，确保交易发起方的真实性；2 不要泄露私钥和助记词；3 不要乱点未知链接和网站，防范高仿域名和内容的NFT钓鱼网站 。
