Personally for me PoC||GTFO fills up the void. They have some good articles and explaining in very friendly way.

Indeed! Reading those issues, for me, is a stream of shock and awe but always learning because the contributors generally give sufficient instructions to perform/confirm their achievements yourself.

Example ... about halfway through Issue 0x02 it is casually mentioned, "You will find by running ‘qemu-system-i386 -fda pocorgtfo02.pdf’ that the PDF file you are reading is also a bootable disk image." o_O !
