There are also zip files that, when uncompressed, yield identical copies of themselves. Dynamic programming methods can be employed to limit traversal of such files, so that only one file is followed recursively at each level, effectively converting their exponential growth to linear. Zip bombs often rely on repetition of identical files to achieve their extreme compression ratios. In many anti-virus scanners, only a few layers of recursion are performed on archives to help prevent attacks that would cause a buffer overflow, an out-of-memory condition, or exceed an acceptable amount of program execution time. The program has a really easy-to-use interface that lets you compress and decompress files by just dragging them on the window.

This zip bomb is freely available for download online. Hamster Free ZIP Archiver is a compression tool that, just like Winrar and Winzip, lets you reduce the size of any file by compressing it into a smaller file.

One example of a zip bomb is the file 42.zip, which is a zip file consisting of 42 kilobytes of compressed data, containing five layers of nested zip files in sets of 16, each bottom-layer archive containing a 4.3- gigabyte ( 4 294 967 295 bytes 4 GiB − 1 B) file for a total of 4.5 petabytes ( 4 503 599 626 321 920 bytes 4 PiB − 1 MiB) of uncompressed data. ZIP Extractor makes use of CORS (Cross-Origin Resource Sharing) methods for uploading and downloading files from Drive. The app is based on the drive.file OAuth2 scope, where permission is granted only for individual files that the user authorizes. However, when the file is unpacked, its contents are more than the system can handle. Hierarchical ZIP files (ZIP files with subfolders) are supported. Details and use Ī zip bomb is usually a small file for ease of transport and to avoid suspicion. Most modern antivirus programs can detect whether a file is a zip bomb in order to avoid unpacking it. Ī zip bomb allows a program to function normally, but, instead of hijacking the program's operation, creates an archive that requires an excessive amount of time, disk space, or memory to unpack. It is often employed to disable antivirus software, in order to create an opening for more traditional malware. In computing, a zip bomb, also known as a decompression bomb or zip of death, is a malicious archive file designed to crash or render useless the program or system reading it.
