the process of reverse engineering machine code is complex and often involves guesswork and analysis of the program's behavior. however, there are disassembler tools available that can help in deciphering machine code and providing a symbolic representation closer to assembly language. can machine langu...
将第一次调用puts改为直接调用outputflag。 然后将修改后的代码保存进原来的exe文件,运行后得到flag Edit-patch program-……File (第一次改了后面的判断那边的汇编代码,导致后面的代码无法被反编译成正常代码被当成垃圾数据舍弃了,然后图形界面运行就会打印一个一闪而过的flag,复现的时候优化了一下。当然使用命令行...

File handling in C language: Here, we will learn to create a file, write and read text in/from file using C program, example of fopen, fclose, fgetc and fputc.
Write a program that asks the user for a number of (at least one) integers.The program should then tell the user which number is the largest,which one is the smallest and the average of all the integers.The average should be rounded to two decimal places.Note:you cannot use Python built...

reverse 回到顶部 0x00 helloworld: 回到顶部 0x01 simple: 都是水题,不再细说 回到顶部 0x03 pyyy 这一题用uncomplye6或者在线网站反编译后,得到的python代码都有大量的lambda操作,读起来十分费力,并且代码不能直接运行,仔细观察,代码中有一行 this_is = 'Y-Combinator' ...
To reverse engineer PyInstaller generated binaries we need to extract its contents. We can usePyInstaller Extractor. Running the script in Python 3.7 in Ubuntu we get the following output. Figure 6: Running pyinstxtractor The scripts points to two possible entrypoints -pyiboot01_bootstrapandpyiboo...
