Introduction
作者：amra13579
HTBCasino 高度重视保障玩家的隐私与安全。为此，赌场聘请您来发现并报告新旧组件中可能存在的安全漏洞。您的目标是在内部网络中获得立足点，提升权限，最终全面攻破整个基础设施，同时在此过程中收集多个标志。此专业实验室旨在测试您在枚举、代码审查、横向移动、Web 利用及其他攻击技术方面的技能。
您需要为以下内容做好充分准备：
- 源代码审查
- Web 应用攻击
- 逆向工程
- Windows 系统利用
- Active Directory 利用
- 区块链利用
- AI 绕过 / 利用

CASINO BlockChains 交易签发漏洞
尝试以 aa123@a.com:123 注册一个账户
在 Contribute 页面
得到了一份 htbchain.zip 压缩文件
经过分析，这个代码实现了一个简单的区块链系统
那么也就是说，需要使用这套区块链系统，往链上签一个恶意的交易（如金额为负的交易），从而使攻击者的余额增加

首先，注册之后，在链上历史会有给攻击者账户转账初始金额的信息
这里的时间对的上的话，字段 receiver_address 就是攻击者的公钥地址
将注册得到的 RSA 私钥和公钥地址填入脚本，然后 签一个恶意的交易上链，即可恶意增加钱包余额
这个时候就可以购买 VIP 权限，然后在左侧就可以看到一个新的功能 Slot
