1、WPA 终结梦魇 -GPU运算 P解 WPA-PSK 加密实战！ Elcomsoft W ireless Security Auditor ElcomSoft 是一家俄罗斯软件公司，出品过不少密码P解软件， 涉及 Office、SQL 、PDF 、EFS 等等。近日ElcomSoft又推出了“ Wireless Security Auditor ”，号称可以利用GPU 的运 算性能快速攻破无线网络密码，运算速度相比使用CPU可提高最多上百倍。本软件的工作方 式很简单， 就是利用词典去暴力P解无线 AP上的 WPA 和 WPA2 密码， 还支持字母大小写、数 字替代、符号顺序变换、缩写、 元音替
2、换等12 种变量设定，在ATI 和 NVIDIA 显卡上均可使 用。 它还通过尝试恢复对 Wi-Fi 通信进行加密的 WPA/WPA2 PSK 初始密码来帮助系统管理员实 现对无线网络安全的监控。通过运用由两大显卡制造商 ATI 和 NVIDIA 提供的硬件加速技 术， Elcomsoft Wireless Security Auditor 已逐渐成为市场上最快速且最具成本效益的 Wi-Fi 密码恢复和无线安全监控工具之一。 说通俗点就是用EWSA 加载“ 握手包 ”并通过电脑的CPU 和 GPU 来跑字典快速完成暴力破解。 在 Core 2 Duo E4500和 Core 2 Quad Q6
3、600处理器上， 该软件每秒钟可以试验480 个 和 1100 个密码， 换成 GeForce GTX 280 、Radeon HD 4870 、Radeon HD 4870 X2 这些显卡能 大幅增至11800 个、 15750 个和 31500 个，而最厉害的是NVIDIA 的视觉计算系统Tesla S1 070，每秒钟可达52400 个 ，相当于 E4500 的 110 倍。 有趣的是， ElcomSoft 声称其中使用了他们“独家开发的GPU 加速技术 ”，而非基于N VIDIA CUDA、ATI Stream或者 OpenCL等。 ElcomSoft Wireless Securit
4、y Auditor支持 Windows NT SP4、Windows 2000、Windo ws XP、Windows Vista 、Windows Server 2003、Windows Server 2008等操作系统，售价 高达 1199 美元 ，不过在今年3 月 1 日钱半价优惠，只要599.5 美元。 ElcomSoft Co. Ltd. 正促成 ATI 和 NVIDIA 硬件共同专注于加强 Wi-Fi 密码恢复。 在 ATI 和 NVIDIA 制作的最新一代显卡功能的支持下，最新发布的 Elcomsoft Wireless Security Auditor 1.0 能够更高速地进行
5、数字运算，从而帮助用户比以往更快找回 Wi-Fi 密码。 Elcomsoft Wireless Security Auditor 可以通过尝试恢复对 Wi-Fi 通信进行加密的 WPA/WPA2 PSK 初始密码来帮助系统管理员实现对无线网络安全的监控。通过运用由两大显 卡制造商 ATI 和 NVIDIA 提供的硬件加速技术，Elcomsoft Wireless Security Auditor 已逐渐成为市场上最快速且最具成本效益的 Wi-Fi 密码恢复和无线安全监控工具之一。 GPU 加速 Wi-Fi 密码恢复 ElcomSoft 独有的最新一代 GPU 加速技术首次同时支持 ATI 和
6、NVIDIA 硬件。该技术 将部分繁重的计算处理卸载到最新款 ATI 和 NVIDIA 主板所特有的高速且高度可升级的处 理器上。 当一款或多款可兼容的 ATI 或 NVIDIA 显卡面市时， 正在申请专利的 GPU 加速技 术就能自动发挥作用了。 这次， ElcomSoft 采用了这项技术来加速对 WPA/WPA2 PSK 密码的恢复，使网络管理员 能够在他们的无线网络上执行定时攻击，以确定其网络究竟是否安全。考虑到 WPA/WPA2 以最短 8 个字符密码实现的强大安全性，Elcomsoft Wireless Security Auditor 以高级变 形实施了最高性能的字典攻击，从而在有
