The Embedded offzip.zip link above provided by arayashiki01 doesn't work
http://aluigi.altervista.org/mytoolz.htmOffset file unzipper 0.3.3 (offzip)
http://aluigi.altervista.org/mytoolz/offzip.zipa very useful tool to unpack the zip (zlib/gzip/deflate) data contained in any type of file included raw files, packets, zip archives, executables and anything else.
it's needed only to specify the offset where the zip data starts or using the useful -S search options able to find any possible zip block contained in the provided file.
naturally there are also other options for extracting all the zip blocks which have been found or dumping them as in their original compressed form.
it's also possible to choose a windowBits value for scanning both the zlib (RFC1950) and deflate (RFC1951) blocks (for example -z -15 for common zip files and so on).
