Locating EOCD in ZIP files by offset
问题 I'm trying to write a collection of yara signatures that will tag zip files based on artifacts of their creation. I understand the EOCD has a magic number of 0x06054b50, and that it is located at the end of the archive structure. It has a variable length comment field, with a max length of 0xFFFF, so the EOCD could be up to 0xFFFF+ ~20 bytes. However, there could be data after the zip structure that could throw off the any offset dependent scanning. Is there any way to locate the record
