2024年是关于许多事情的一年,其中之一是加密行业转向网络钓鱼作为最严重的网络威胁形式,共发生296起攻击,造成行业损失10.5亿美元。根据Certik的Hack3d报告,这占去年被盗加密资产的40%,证明网络钓鱼仍然是最有效的网络攻击工具。
总体而言,平均每次网络钓鱼攻击的成本为280万美元,中位数为20.7556万美元。实际上,尽管黑客决定向受害者退款2.13亿美元,但调整后的损失仍接近8.36亿美元。
最多的攻击发生在以太坊网络上,共有248起,总损失为2.975亿美元。币安智能链(BSC)也成为网络钓鱼者的另一个常见目标。
从年度观察来看,网络钓鱼攻击的损失大幅上升。实际损失也在上升,特别是在2023年至2024年间,上升了328%,这证明此类攻击不仅在频率上升,而且在复杂程度上也升级了。
为什么网络钓鱼攻击会成功?
网络钓鱼并不试图突破技术保障,而是利用用户的弱点获取私钥或钱包密码等信息。钓鱼邮件、假网站和欺骗性消息是诈骗者最常使用的手段。
在加密货币的背景下,它的一个独特特点是一旦交易被签名,就无法停止或撤销,这就是网络钓鱼尤其危险的地方。
如何保护自己免受网络钓鱼攻击?
要保护自己免受网络钓鱼攻击,一些简单的预防措施可以大大提高安全性。尽量不相信并对来自陌生来源的消息或任何形式的沟通持怀疑态度。在点击链接之前,始终验证其合法性和发送者。
使用硬件钱包存储多余的加密货币是最安全的措施之一,它可以作为黑客无法突破的一层防线。在转移资金时,请确保检查接收方的钱包地址,以确保未被更改或地址被篡改。

为了进一步提高安全性,可以启用双因素身份验证,并定期更新软件,使用防钓鱼工具如网络扩展。在进行与加密货币相关的所有操作时,请使用安全的网络连接,因为通过公共Wi-Fi连接存在高风险,如网络钓鱼和中间人攻击。function logSelectedSubscriptions(categoryid) {
