A zip bomb is acompressed filethat consumes a massive amount of storage space when decompressed. When a zip bomb is opened, it can quickly take up all the free space on astorage device. MostZipfiles have a compression ratio between 2:1 and 10:1. For example, a 3megabytecompressed.ZIPfi...
1. 解释什么是“zip bomb” “Zip bomb”指的是一种恶意的压缩文件,该文件在压缩时体积很小,但解压后会占用极大的磁盘空间,远远超出其压缩文件的大小比例。这种文件通常被用于网络攻击,通过诱导用户下载并解压,从而消耗系统资源,甚至导致系统崩溃。 2. 说明为何会检测到“zip bomb” 当解压一个压缩文件时,系统会...
header("Content-Length: "+ filesize(ZIP_BOMB_FILE_10G)); // 10 MB readfile(ZIP_BOMB_FILE_10G); exit; } 这就够了。唯一的代价是,我现在有时要提供 10MB 的文件。如果有一篇文章要进行病毒式传播,我会将其减小到 1MB 文件,这样同样有效。 还有一点,压缩炸弹并非万无一失。它很容易被发现和规避。
For example, if the process is creating 10 unzipped files, it will need 10 times processing resources, 10 times memory, 10 times disk space, and 10x times. So, zip bombing a big file will surely make the host system crash. Zip Bomb - Is It a Virus? Though it acts and appears...
Zip bomb toolshttps://www.bamsoftware.com/hacks/zipbomb/David Fifield <david@bamsoftware.com> Public domain zipbomb is a Python 3 script that generates zip bombs according to parameters. Example: python3 zipbomb --mode=quoted_overlap --num-files=250 --compressed-size=21179 > zbsm.zip See...
Self-replicating: this is the most complex zip bomb. It is a zip file that replicates itself when decoded, creating a recursive process. So, these bombs require data files with specific features to work. A known example of such a category is ther.zip file ...
If you need the extracted files to start with a certain prefix (so that they will be identified as a certain file type, for example), you can insert a data-carrying DEFLATE block just before the block that quotes the next header. Not every file has to participate in the bomb construction...
ZipBomb The result of attempting to create an insanely large zip bomb, a file that is so large, there is no storage big enough to hold the extracted contents ever. How to The procedure is simple: Create a 4 Gigabyte (4*1024*1024*1024Bytes) file and compress it once. Name itBase.zip...

For example, decompression bombs (aka ZIP bomb) apply to zipfile library that can cause disk volume exhaustion. Interruption Interruption during the decompression, such as pressing control-C or killing the decompression process may result in incomplete decompression of the archive. Default behaviors of...
