中间人攻击在这些攻击中黑客将自己置于用户和服务器之间拦截通信。 它们可以窃听和修改它们之间传输的数据获取登录凭证或财务细节等敏感信息。降级攻击此类攻击以 SSL 协议为目标迫使通信使用过时的版本如 SSL 3.0。 攻击者可以利用协议中的弱点对加密流量进行解密。SSL 剥离攻击这些攻击利用 HTTPS 连接建立方式中的漏洞。 攻击者拦截用户与网络服务器之间的流量并将连接降级为 HTTP。 由于用户和服务器之间传输的其他敏感数据没有像 HTTPS 连接那样加密因此这种操作允许他们查看和操作这些数据。SSL 重新协商攻击网络犯罪分子利用客户端和服务器之间 SSL 流量重新协商的缺陷。 通过操纵这一过程他们可以在通信中注入恶意代码或命令从而可能破坏连接。会话劫持攻击在这些攻击中攻击者会窃取用户或服务器的会话验证证书或私钥从而冒充证书持有者。 这样他们就能在任何一方都没有意识到自己受到威胁的情况下拦截和操纵传输。SSL 注入攻击这些漏洞涉及通过 SSL 流量在用户和服务器之间的通信中注入恶意代码或命令。 因此黑客会在未经授权的情况下获取敏感信息。漏洞

2014 年的Darkhotel 攻击是中间人攻击的一个突出真实案例。 在这场复杂的网络间谍活动中黑客潜入了政府官员和企业高管等高级别客人经常光顾的酒店 Wi-Fi 网络。

2014 年谷歌研究人员 Bodo Möller、Thai Duong 和 Krzysztof Kotowicz 发现了这个名为[POODLE 的漏洞](https://www.ssldragon.com/zh/blog/what-is-poodle-attack-ssl/)。 这次攻击的目标是 SSL 3.0 加密协议当时网络服务器和浏览器仍广泛支持该协议。
