Zip bomb

Rare card · No. 64997

In computing, a zip bomb, also known as a decompression bomb or zip of death (ZOD), is a form of algorithmic complexity attack that uses a malicious archive file designed with the goal to crash or freeze the program or system reading it. The older the system or program, the less likely it is that the zip bomb will be detected. It is often employed to disable antivirus software in order to create an opening for more traditional malware. A zip bomb allows a program to function normally, but instead of hijacking the program's operation, it creates an archive that requires an excessive amount of time, disk space, computational power, or memory to unpack. Most modern antivirus programs can detect zip bombs and prevent the user from extracting anything from it.
