1. Load the resource (instead of opening the file)
2. Convert all reads from the file to memcpy() operations
3. Discard the resource (instead of closing the file)

string resource = "Installer.Resources.myFile.zip";
System.Reflection.Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
Stream resFilestream = a.GetManifestResourceStream(resource);

ZipArchive archive = ZipFile.OpenRead(resFilestream);

ZipArchive archive = new ZipArchive(resFilestream);

Unzip file from resources directly without copy it to outside of resources first

So a 1k zip file is ok but if it is possible and you do not specifically code a check for this, that the file is 100 meg or 1 gig, then unzipping in memory is going to be a problem.

Zip bomb - Wikipedia[^]:

One example of a zip bomb is the file 42.zip, which is a zip file consisting of 42 kilobytes of compressed data, containing five layers of nested zip files in sets of 16, each bottom layer archive containing a 4.3-gigabyte file for a total of 4.5 petabytes of uncompressed data.
