Most antivirus are able to detect zip bombs. In this modern day. Zip bombs doesn't cause much effect or not at all to systems.
Antivirus scans 3 downlevel usually unless you changed the settings so
Zip bombs don't cause AV to crash therefore does not "create" a scenario where AV crashed and opportunity arises for malware to infect the system.
System Processes now work more efficiently as compared to earlier days when zip bombs are reigning.
If unpacking zip bombs consumes memory. It pretty much are contained within the process. The process handling the extraction would just run out of memory and crash.
Writing a script and slowly extracting the zip bombs does not make a dent in the system, running out of space, the unzipping would fail.
Again modern day systems running into low disk space will sound a 'low disk space's warning. All the user needs to do is find large files and just deleting them.
Even if disk spaces are full, system will still run at minimal mode.
Zip bombs are not what its name says it is. When you unzip a zip bomb, it doesn't "explode" in a grand fashion. If you use the extract all function. It's just gonna crash. Period.
So what about possible use case?
I probably say use it to troll someone, wasting 10secs of their life? But then again you be wasting your time and effort creating it.
In my opinion it isn't worth doing it now.
