skitter-creek-bath-salts

skitter-creek-bath-salts 通过 DRAM 扰乱在 CPU 上解锁一切 ——PSP、C6、微码、SMM，以及规格文档遗漏的所有其他内容。 &x == &x。 通常如此。 拨弄 DRAM 控制器，就能让一个地址落在内存中你想要的任何位置。skitter-creek-bath-salts 修改内存层次结构的底层，重新布线物理 DRAM 地址转换。这会扰乱平台内存，暴露 DRAM 中受保护的区域——那些连内核都看不见的保留区。当地址转换被破坏时，建立在其上的安全原语也随之崩溃，于是我们解锁了 一切 。 太长不看 解锁你的平台安全处理器 解锁系统管理模式 解锁 C6 DRA...

smiiiiiiiiiiiiiiii

smiiiiiiiiiiiiiiii 利用一个非常非常非常非常非常非常长的中断来攻击系统管理模式（SMM）。 概述 事实证明，你可以仅凭一条极其耗时的机器指令，就攻破 SMM——这个在每颗 x86 CPU 后台隐形运行的安全、超特权执行环境。 SMM 要求所有核心要么同时处于 SMM 中，要么同时处于 SMM 外。它的安全模型离不开这一点——当一个线程进入 SMM 时，它会强制所有其他线程也进入 SMM。 要打破这一点，我们只需要一个忙到没注意到自己应该加入 SMM 的核心。 其原理大致如下： root@kitploit: 核心 0 - 开始一条长指令 | | | 核心 1 - 邀请核心...
