Breaking the x86 Instruction Set

中文导读

Christopher Domas 在 Black Hat 2017 上的高分技术分享。他利用缺页异常分析与处理器模糊测试对 x86 指令集进行穷举挖掘,不仅找出了未公开指令与硬件级漏洞,还指出了传统反汇编工具的认知盲区。

为什么 HN 推它

围绕 Sandsifter 工具展开的逆向神作,构思精巧、风趣幽默又极具启发性,把晦涩的芯片底层漏洞挖掘讲得引人入胜。

「整个过程通俗易懂,而且非常有趣生动。」HN 网友原话:I found it easy to follow and pretty entertaining.
英文原摘要(HackerTube / Claude 整理)

Christopher Domas presents at Black Hat 2017 how page fault analysis and processor fuzzing can exhaustively search the x86 instruction set. The talk uncovers undocumented instructions and hardware bugs and shows limits of disassemblers.

HN recommends it as a clever, entertaining and easy-to-follow talk on finding hidden x86 instructions with the Sandsifter tool.
