Suppose we have a complete implementation of SFI on a CPU hardware that is vulnerable to meltdown attacks that also happens to run a Linux kernel that is also vulnerable to meltdown attacks. Can SFI alone prevent these meltdown attacks fro… Continue reading Can Software-based fault isolation (SFI) prevent meltdown?
PC-104 is a standard computer form factor that most people outside of industrial settings probably haven’t seen before. It’s essentially an Intel 486 processor with lots of support for standards …read more Continue reading DOS Gaming PC Gets Necessary Updates
For an old CPU, finding all the valid instructions wasn’t very hard. You simply tried them all. Sure, really old CPUs might make it hard to tell what the instruction …read more Continue reading Undocumented x86 Instructions Allow Microcode Access
David Letterman made the top ten list famous. [Creel] has a top ten that should appeal to many Hackaday readers: the top 10 craziest x86 assembly language instructions. You have to admit that the percentage of assembly language programmers is …read more
Microprocessor giant Intel has announced the 11th-generation Core vPro, H-series, and S-series processors, plus new Pentium Silver and Celeron processors.
The post Intel Announces Four New Processor Families at CES 2021 appeared first on Thurrott.com.

The x86 processor family is for the time being, the most ubiquitous type of processor in the PC world, and has been since the 1980s when the IBM PC came on the scene. Emulating these older devices is easy enough if you want to play an old LucasArts game or …read more

My goal is to obfuscate metasploit windows payloads’ assembly code (adding junk code to the payload itself), then adding the obfuscated shellcode to inline assembly in C. The issue is there is no format command line argument (-f) that prov… Continue reading msfvenom: how to output assembly of windows payload for inline assembly in C?
From the old Gumstix boards to everyone’s favorite Raspberry Pi, common single-board computers (SBCs) have traditionally had at least one thing in common: an ARM processor. But that’s not to say hackers and makers haven’t been interested in an SBC with a proper x86 processor. Which is why the $99 …read more
