With that I am trying to unpack various upx that are not modified or custom passworded etc. Still with any upx unpacker gui I try none can unpack them. About time UPX team built and maintained a GUI for UPX that works not matter how packed with a UPX binary (unmodified).
Sure I also tried the one in the downloads and that one even fails. Time we had better can't be that hard for UPX team to maintain one, can it !
Excuse the above I was wrong have just checked with pied and Advanced Scan (Diabloo2oo2 plugin) (9431 in database) showing that all known ep_only are not upx signatures. As sometimes happens what is shown in the hex is not always correct even if it says UPX1.
Pied itself without plug-in use all say UPX v2.0 -> Markus, Laszlo & Reiser * or say nothing.
Meaning these are packed with custom or other packer. While Trid hasn't a clue as usual. Time to use other options for these.
Prefer GUI over Command Prompt each time for any software including UPX options
