How to identify a Zip Bomb File

A zip bomb, also known as a decompression bomb, is a restricted archive file that contains a large amount of repeating data that can cause a program to crash when it is read. A zip bomb, often known as the "zip of death," is frequently used to render an antivirus application inoperable, allowing more traditional malware to enter a system. A computer virus, sometimes known as a 'virus,' is a sort of malware software that attaches itself to an executable program or a file and then spreads through other programs and files, infecting files along the way. To learn more, enroll in cyber-crime courses online. A virus can harm your vulnerabilities in a computer system in a variety of ways once it is executed; it can reproduce files and directories, significantly increase CPU load, steal hard disc space, destroy data, spam contacts, and many other unpleasant things.


Decompression explosives are usually used maliciously. Zip bombs are used by threat actors to disable antivirus software on a PC. After it has been disabled, hackers can gain access to the system and infect it with additional software, such as viruses, spyware, and ransomware. Zip of death assaults is primarily used to take up space on virus scanners. Enroll in a cyber security course to have deeper knowledge.

Antivirus software checks the contents of compressed archive files for harmful software. However, due to the nature of zip bombs, the virus scanner could take many days to scan. If a recursive decompression bomb file is being scanned, the virus scanner can even consume all system memory or crash. While the virus scanner is working with the decompression bomb, other dangerous software can infiltrate the system and infect it.

Workings of Decompression Bombs

The traditional decompression bomb is a little zip archive file, the majority of which are measured in kilobytes. When the file is unzipped, the contents are too large for the system to handle. A standard zip bomb file can unzip to hundreds of terabytes of meaningless material. Register for cyber security certifications to advance your career. Advanced decompression bomb files can be millions or billions of gigabytes in size, sometimes known as petabytes and exabytes. Instead, then interfering with a program's usual operation, a decompression bomb allows it to operate normally. However, the archive file is designed in such a way that extracting it takes a long time, a lot of disc space, and a lot of memory.

Identifying a Decompression Bomb

Most recent antivirus applications can detect zip bombs by checking for files that overlap. They are aware that unpacking layer after layer of exploited data indicates the presence of a decompression bomb. Antivirus software frequently incorrectly classifies a file as a decompression bomb when it is not. To learn more about zip bombs, take cyber-crime courses online. Users can Google the file name to discover if others have reported a difficulty with the same file to identify if the file is a zip bomb. Additional safeguards that users can take to defend their computers from the zip of death assaults include the following:

  • Files of 2 KB or more should not be unzipped
  • Use reputable antivirus software such as avast and norton
  • Download files only from reliable websites.

Zip Bomb Disposal

Users can use the Reimage computer repair tool or a similar program to restrict zip bombs from their systems. Reimage searches a system for harmful files and things. The decompression bomb file will be erased once the repair operation is finished. Users should then restart their PCs to complete the procedure, making sure the decompression bomb is no longer present. To advance your profession, enroll in a cyber security course.

Bomb Decompression Effects

A decompression bomb, on its own, does not harm a system in the same way that a regular computer virus does. On the other hand, opening a file classified as a decompression bomb will immediately cause the system to hang, eventually causing it to exploit and cause permanent data loss.


A decompression bomb is a malicious archive file that contains a huge quantity of compressed data. It is also known as a zip bomb or zip of death attack. When the file is opened, it has the potential to crash the software that is reading it as well as wreak havoc on the rest of the system. Decompression bombs are frequently used to deactivate antivirus software. Enroll in cyber security certifications to increase your knowledge.
