Is it possible to integrate a decompression bomb in a Comic Book Archive file?
Question by AllenRayz /

Can a Zip bomb (decompression bomb) somehow possibly be integrated into a Comic Book Archive file? I know this is a bit far fetched, but anyway?

    zip files and comic book archive files like cbr or cbz are same. if you want to convert zip to cbr or vice versa you can just rename the extension. so since they are the same you can do what you want to do with either of the files.

    Did you get bombed? or are planning to bomb someone? One will warrant an answer the other well we are not here to encourage people to unleash malicious code. But in theory yes you can almost anything that is compressed can be modified to have an exponential increase in data upon unpacking.

      Yeah. I wonder what he’s going to do with the info. Questions are moderated, so I’m taking a safe bet he asks for the sake of mere curiosity, but one can’t be too wary.

    It is an exe or zip which has been zipped more than once. the archive is carefully crafted so that unpacking it requires inordinate amounts of time, disk space or memory.

    There are three types of bombs: incorrect header in the archive, repeated data and series of identical files in the archive.

    In theory, yes- the only major difference between a comic book archive file and that archive type in general is the extension (for example, .zip is the same type as .cbz just with a different name extension).

    So basically, anything that can be done with a .zip file can be done with a .cbz file. It’s the same with the other types as well (rar and cbr, 7z and cb7, tar and cbt, etc.).

    Can you tell us the reason you want the information? Of course it might be mere curiosity on your part, but you’re asking about the possibility to sneak in questionable code into an archive file.
    Sorry, just a bit of suspicion. Anyway, I think it’s possible, since Comic Book Archive is essentially ZIP//RAR/other compression pack for specialized use, hence there is high possibility it has the same weakness as normal ZIPs.
