Introduction In CTF competitions, the RSA encryption system is a very common examination point. Because the RSA encryption and decryption algorithm is based on number theory problems, if not designed properly, it can easily lead to vulnerabilities that allow plaintext to be leaked. This article summarizes common exploitation scenarios and code analysis for CTF-RSA, providing … Read more

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
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
