@x64dbgbot
<kofteror> Yup..
x64dbgbot
@x64dbgbot
<mrexodia> Some elaboration would be good. What do you mean with “add”? Like append to the executable? (re @kofteror: Hey, can i add assembly lines in x64dbg?)
<mrexodia> Sorry I forgot to answer. Check the “mov” instruction (re @x64dbg_bot: <Forlax> mrexodia, is this possible with the current engine that x64dbg uses or it's not in there yet. Because I got no clue, I asked around and they sent me here.)
<mrexodia> You can mov a byte pattern in a location
<mrexodia> And there is also a command to assemble
x64dbgbot
@x64dbgbot
<levitanious> @kofteror If you talk about inline assembly during debugging -- yes.
<levitanious> Right click on an opcode and then -- assemble. You can find code caves or make your own.
<levitanious> Then you just assemble whatever you want there and then patch to preserve changes.
<mrexodia> Also multimate assembler is a great plugin worth mentioning

@x64dbgbot
<billy-jon> there seems to be a bug relating to int3 bps and remapping. bps get to a point where the disassembly view does not show them as present, but the bp window says they are and enabled. when that happens, i cannot delete them, or enable/disable
<billy-jon> it seems like it has something to do with how bps are stored. if i create them after the remapping, im guessing that the debugger doesn't know to store them as relative to a particular module's base address and instead stores absolute addresses
<billy-jon> but if i restart the process and there now IS a module there, even though the literal address is unchanged, things bug out
x64dbgbot
@x64dbgbot
<mrexodia> Remapping?
<mrexodia> Breakpoints are stored as module+rva or if there is no module as an absolute address
x64dbgbot
@x64dbgbot
<billy-jon> sorry, i had been under the impression that you have looked at the blizzard anti debug stuff. they will remap the binary with CreateFile(), memcpy, MapViewOfFile() or some such thing to give SEC_NO_CHANGE to the whole binary. just like what is described here: https://github.com/changeofpace/Self-Remapping-Code
<billy-jon> incidentally it would be awesome if the db files for each program could be plaintext like json or something so i could go and remove those bps manually
<Nukem> they are plaintext/json if compression is disabled
<billy-jon> once the debugger encounters an int3 bp it doesnt expect to be there, i cant figure out how to get execution to continue
<billy-jon> oh look at that, thanks
x64dbgbot
@x64dbgbot
<billy-jon> okay so yeah the problematic bps seem to be ones that i created after the remap
<billy-jon> they are in the dd64 file for the binary as absolute addresses
<billy-jon> if i start the process, paused at the entry point, i cannot delete those bps
<billy-jon> it says: No such breakpoint "0x<address>"
<billy-jon> erm, no 0x
x64dbgbot
@x64dbgbot
<billy-jon> if i allow the app to execute until the remap happens, and use the ForcePageProtection plugin, i can disable, but not enable the bp. when i try to re-enable the bp in this case it says: Could not enable breakpoint <address> (SetBPX)
x64dbgbot
@x64dbgbot
<billy-jon> it seems like there is some kind of sanity check on whether an int3 is due to a bp created by the debugger, and that sanity check does not support remapped code. something like this: "is_my_int3(ea) { if is_in_module(ea) and rva_bp_exists(ea_to_rva(ea)) { return true; } else if abs_bp_exists(ea) { return true; } else { return false; }"
<billy-jon> but probably when the bp is first applied it should remember the ea and check against that later on
x64dbgbot
@x64dbgbot
<mrexodia> Did you try using a virtual module? (re @x64dbg_bot: <billy-jon> okay so yeah the problematic bps seem to be ones that i created after the remap)

@x64dbgbot
<billy-jon> mrexodia, no i dont think i knew that x64dbg could do that
<mrexodia> “Can do that” haha
<mrexodia> More like kinda can do it maybe

@x64dbgbot
<Nukem> quality 👏 software 👏

<levitanious> (free and open-source, tho)
<levitanious> (also pretty badass)
<levitanious> A wise old man once said: "You make a punchline of what i cannot do and berate me for what i can... send, patches young one!" 😂
<kaens> People would even berate the wise men :<
x64dbgbot
@x64dbgbot
<levitanious> I mean, i'm no wise man and i guess the old man was clearly trying to make it into reddit's fp at a time
<levitanious> But the idea! That matters.
<levitanious> <attempt at humour, badum-tsss>
<kaens> A wisecracker is one who can make em patches, amirite?
<Nukem> lol
<kaens> Wish I could chat to the Chinese community. Keep seeing so many weird protections for minor engines

@x64dbgbot
<billy-jon> im not making jokes about it. i just didnt know it could.

<shepz> Hi, who know StrongOD where can buy ? :)
x64dbgbot
@x64dbgbot
<shepz> who have plugin or bypass vmprotect on x64 ( ScyllaHide dont work on my file ) PM
<mrexodia> Just read the ScyllaHide issues or use titanhide
x64dbgbot
@x64dbgbot
<hans_> wonders how to check if one is banned from a github issue tracker or not
x64dbgbot
@x64dbgbot
<hans__> any idea if TitanHide constantly has an open handle to C:\TitanHide.log or if it's just opened when it needs to be?
<hans__> nvm, it's the latter
