Buuctf misc 面具下的flag

这篇博客介绍了如何通过UltraEdit和binwalk工具从一张名为'mianju.jpg'的照片中提取隐藏的flag.vmdk文件,并进一步分离出多个文件。博主使用在线解码工具对key_part_one和key_part_one的两个文件进行解码,最终得到flag:flag{N7F5_AD5_i5_funny!}

下载文件,得到一张命名为mianju.jpg的照片

利用UltraEdit(16进制编辑器)打开该图片

发现里面存在一个flag.vmdk文件

利用kail中的binwalk对该图片进行分离

发现里面存在若干个文件

 打开key_part_one的NUL和key_part_one的where_is_flag_part_two.txt:flag_part_two_is_here.txt文件

利用在线解码工具对其进行解码

### BUUCTF Miscellaneous Challenge Flag Solution For solving a BUUCTF miscellaneous challenge and finding the associated flag, one must approach such challenges methodically by understanding the provided materials or context within which the challenge operates. Since specific details about this particular BUUCTF misc challenge are not directly given here, general strategies can be outlined based on common practices in CTF (Capture The Flag) competitions. In many cases, flags for miscellaneous challenges follow certain patterns like `flag{...}` where ellipsis represents some text that needs to be discovered through problem-solving techniques relevant to the task at hand[^1]. Participants often need to apply skills ranging from steganography, cryptography, reverse engineering, to web exploitation depending upon what type of puzzle has been set up by organizers. To solve a miscellaneous challenge effectively: - Carefully read all information provided alongside the question. - Look out for any hidden messages embedded within images, audio files, or documents shared as part of the clue. - Experiment with different tools designed specifically for uncovering concealed data. - Consider how elements might relate back to known algorithms or protocols mentioned either explicitly or implicitly during the description. A concrete example cannot be demonstrated without knowing specifics about the current BUUCTF misc challenge being referred to because each scenario varies greatly in terms of required knowledge areas and methodologies employed. --related problems-- 1. What types of puzzles commonly appear under the category of miscellaneous in CTF events? 2. How does one prepare generally for tackling diverse kinds of challenges found in Capture The Flag contests? 3. Can you provide an overview of popular resources used when attempting to decode obscured communications encountered in CTF games? Note: Direct solutions including actual flags should typically come from participating officially in respective CTF activities rather than external sources so as not to compromise fairness among competitors.
