IRONSQUIRREL 本项目旨在以加密方式向受害者浏览器传递浏览器漏洞利用代码。采用椭圆曲线 Diffie-Hellman（secp256k1）进行密钥协商，并使用 AES 进行加密。 通过以加密方式向受害者传递漏洞利用代码（和 shellcode），攻击无法被重放。同时，HTML/JS 源代码经过加密，从而显著增加了逆向分析漏洞利用代码的难度。 如果您不明白我在说什么，请搜索“如何隐藏您的浏览器 0-day 漏洞”，并查看我的演讲。或者可以在 YouTube 上观看：https://www.youtube.com/watch?v=eyMDd98uljI 或者查看 SlideShar...
