 Posted: Mon Jan 17, 2022 8:10 am Post subject: luacode section not functional in generated trainer |
 |
|
may I know if new {$LUACODE} function in CE7.3 works in generated trainner?
I got a old trainner code(execute a codeinjection AAscript ) upgrade to luacode,and it works well in CE,but if compiled it as a standalone trainner,it will not functional to write AAscript code injection to target process(verified by using CE to check the memory)
for simply concept the keypart code just like:
| Code: | --controlMainForm = getMainForm()
xx=false
function enableit()
scan="B8 ? ? ? ? E8 "
x=AOBScanUnique(scan)
registerSymbol("subaddr",x)
mem=allocateMemory(0x2048)
registerSymbol("newmem",mem)
script=[[
label(returnhere)
label(originalcode)
label(exit)
newmem: //this is allocated memory, you have read,write,execute access
//place your code here
push rax
pushfq
{$luacode tt=r9}
x=readString(tt,5000)
http=getInternet()
c="data="..urlEncode(x)
s=http.postURL("http://127.0.0.1/log",c)
http.destroy()
{$asm}
jmp originalcode
originalcode:
popfq
pop rax
mov rax,rsp
mov [rax+08],rbx
exit:
jmp returnhere
subaddr:
jmp newmem
nop 2
returnhere:
]]
ax=autoAssemble(script)
end
function disableit()
--writeBytes(x,0x48,0x8B,0xC4,0x48,0x89,0x58,0x08)
--writeBytes(x,0x48,0x8B,0xC4,0x48,0x89,0x58,0x08,0x48,0x89,0x70,0x10,0x48,0x89,0x78,0x18)
--writeBytes(x,0x48,0x8B,0xC4,0x48,0x89,0x58,0x08)
writeBytes(x,0x48,0x8B,0xC4,0x48,0x89,0x58,0x08,0x48,0x89,0x70,0x10,0x48,0x89,0x78,0x18,0x4c,0x89,0x48,0x20,0x55)
unregisterSymbol("newmem")
unregisterSymbol("subaddr")
deAlloc(mem,0x2048)
mem=nil
scan=nil
x=nil
ax=nil
end
--writeBytes(x,0x48,0x8B,0xC4,0x48,0x89,0x58,0x08,0x48,0x89,0x70,0x10,0x48,0x89,0x78,0x18,0x4c)
--48 8B C4 48 89 58 08 48 89 70 10 48 89 78 18 4c 89 48 20 55 41 54 41 55 41 56 41 57 48 8d a8 68EDFFFF
function CETrainer_CEButton1Click(sender)
if not(xx) then
enableit()
xx=true
CETrainer.CEButton1.setCaption("Disable")
else
disableit()
xx=false
CETrainer.CEButton1.setCaption("Enable")
end
end

looks like I forgot to add the luacode required files to the exe pre-built options
You'll need to add luaclient*.dll files to the .exe package (use the add file(s) option in extra files for that)(

Thanks So Much Dark Byte!
and here is another question:
Is luacode section thread safe?
for example the codeinjection in original post
will may executed by mutlithread in target process
(in fact it's a network packet function,and where codeinejction injected was a code section shared in multiple tcp socket client in target process, one socket client one thread,I'm trying to log every packet data by that injection and post it to local webserver to save)
so,if luacode executed concurrently ,for example instancehttp1=getInternet() ,will the instancehttp1instance here shared across multiple thread is same instance?if not,will it block and hang to execute one by one(sometimes the webserver may slow to response)?

the luacode section runs in it's own thread, so don't access gui code unless you synchronize() it with the main thread first
Also, right now, only one luacode section can run at a time, so if you take a long time, or even wait for some other lua code, it'll freeze the target process
(Instead of luacode you may want to use createThread(function()) )

found a post /viewtopic.php?t=611040 said Lua is not thread-safe,got some clue.
may I confirm the gui code you mentioned here is the gui thread in trainner,not the render thread in game?
and createThread might not suitable here since the Shared Packet Process Code Section is in inside different Network Thread and managed by game process itself?
so the createThread might not suitable in this situation but we may create multiple LuaThread in trainner.exe when needed when it's a function we can directly execute(for ex a loop that consistently add 1 health per seconds)
im assume it works like follow picture

CE's gui thread yes
you may want to implement a producer/consumer mechanic as postURL can take a while.
example: network thread 1 calls luacode, then network thread 2 and 3 have to wait till network thread 1 has finished sending the data
(you can also write the data to a file if it's localhost only)
