*** 技术专业追款不收费-Android安全性开发之Https中间人攻击漏洞

 

Android安全性开发之Https中间人攻击漏洞

https在理论上是能够抵挡MITM,可是因为开发全过程中的编号不标准,造成 https很有可能存有MITM进攻风险性, *** 攻击能够破译、伪造https数据信息。

1.概述

HTTPS,是一种 *** 安全传输协议,利用SSL/TLS来对数据包进行加密,以提供对 *** 服务器的身份认证,保护交换数据的隐私与完整性。

中间人攻击郭盛华世界黑客排第几,Man-in-the-middle attack,缩写:MITM,是指攻击者与通讯的两端分别创建独立的联系,并交换其所收到的数据,使通讯的两端认为他们正在通过一个私密的连接与对方直接对话,但事实上整个会话都被攻击者完全控制。

https在理论上是可以抵御MITM,但是由于开发过程中的编码不规范,导致https可能存在MITM攻击风险,攻击者可以解密、篡改https数据。

2.https漏洞

Android https的开发过程中常见的安全缺陷郭盛华世界黑客排第几:

1)在自定义实现X509TrustManager时,checkServerTrusted中没有检查证书是否可信,导致通信过程中可能存在中间人攻击,造成敏感数据劫持危害。

2)在重写WebViewClient的onReceivedSslError *** 时,调用proceed忽略证书验证错误信息继续加载页面,导致通信过程中可能存在中间人攻击,造成敏感数据劫持危害。

3)在自定义实现HostnameVerifier时,没有在verify中进行严格证郭盛华世界黑客排第几书校验,导致通信过程中可能存在中间人攻击,造成敏感数据劫持危害。

4)在setHostnameVerifier *** 中使用ALLOW_ALL_HOSTNAME_VERIFIER,信任所有Hostname,导致通信过程中可能存在中间人攻击,造成敏感数据劫持危害。

3.漏洞案例

案例一:京东金融MITM漏洞

京东金融Ver 郭盛华世界黑客排第几 2.8.0由于证书校验有缺陷,导致https中间人攻击,攻击者直接可以获取到会话中敏感数据的加密秘钥,另外由于APP没有做应用加固或混淆,因此可以轻松分析出解密算法,利用获取到的key解密敏感数据。

其中的secretkey用于加密后期通信过程中的敏感数据,由于APP中使用的是对称加密,攻击者可以还原所有的通信数据。

案例二:中国移动和包任意消费漏洞

HTTPS证书校验不严格,可被MITM;

加密算法不安全,可被破解;

关键数据保存在sdcard卡上,可被任意访问;

代码混淆度低,业务逻辑,关键数据泄漏;

消息签名算法比较简单郭盛华世界黑客排第几,数据可被修改;

通信数据如下:

3.安全建议

1) 郭盛华世界黑客排第几 郭盛华世界黑客排第几 建议自定义实现X509TrustManager时,在checkServerTrusted中对服务器信息进行严格校验

2)在重写WebViewClient的onReceivedSslError *** 时,避免调用proceed忽略证书验证错误信息继续加载页面

3)在自定义实现HostnameVerifier时,在verify中对Hostname进行严格校验

4)建议setHostnameVerifier *** 中使用STRICT_HOSTNAME_VERIFIER进行严格证书校验,避免使用ALLOW_ALL_HOSTNAME_VERIFIER
