Analysis of ARM Bare-Metal Programs

One Introduction Often, programs run without an operating system, which is known as bare-metal operation and cannot run directly in Linux. Therefore, alternative methods must be used for analysis. Taking a CTF problem as an example, we will learn about analyzing bare-metal programs on the ARM architecture. Two Analysis Program address: https://dn.jarvisoj.com/challengefiles/confusedARM.hex.f4e616545ff1a18526b9d1c90ea648ff This program is … Read more

CTF Assembly Challenge: Learning ARM and X86 Assembly

The problem is relatively simple but tests the basics of binary assembly.I personally think that the fundamentals are veryimportant, so I spent some time carefully studying this problem to solidify my foundation.If it wereoffline, without GPT’s help, contestants would need a solid understanding of assembly to conduct a detailed analysis of the problem. If you … Read more
