Feasibility of CPU Backdoors
Recently I was thinking of the feasibility of hardware backdoors in the CPU introduced by manufacturers at the behest of three letter agencies. I can think of two potential backdoors that seem extremely powerful, but want to see if they wo… Continue reading Feasibility of CPU Backdoors
Linux X86 Assembly – How To Make Payload Extraction Easier
Overview In the last blog post of the X86 Linux assembly series, we focused on how to make our Hello World payload friendly for use as a payload in exploits. However, we didn’t cover how to extract the payload itself for use in exploits. Sure you cou… Continue reading Linux X86 Assembly – How To Make Payload Extraction Easier
Software Defined… CPU?
Everything is better when you can program it, right? We have software-defined radios, software-defined networks, and software-defined storage. Now a company called Ascenium wants to create a software-defined CPU. They’ve …read more Continue reading Software Defined… CPU?

Is it possible to extract encryption keys from software executing on your own system?
I’m a newbie in this field so forgive me in advance if this question is stupid in anyway.
Say we have a software that is executing on our system and encrypting files using a secret key that is not known to us. Is it possible to somehow gai… Continue reading Is it possible to extract encryption keys from software executing on your own system?
Can a custom built CPU break hard drive encryption?
While a hard drive is decrypted on boot up, can the original phrase be intercepted at some comparison calculation step by a specially built CPU or is there some higher math involved?
This would be blatant, so I guess not. But would like to… Continue reading Can a custom built CPU break hard drive encryption?
One Bit CPU Runs at a Blistering 60Hz
If you really think hard about it, a CPU is just a very general-purpose state machine. Well, most CPUs are, anyway. The MC14500 is a one-bit computer that has only …read more Continue reading One Bit CPU Runs at a Blistering 60Hz
