 Posted: Thu Oct 01, 2015 9:38 am Post subject: Unlimited BREAKpoints?¿ |
 |
|
Hello fellows.
Recently i ran into a problem with the app i'm trying to debug.
I have a LUA script that sets lot of breakpoints in a code (usually at the beginning of functions).
It works great but the code i'm debugging uses..."integrity checks" i think it's called, so...some functions are checked "What does it mean?"
Checked means that if any byte of the function is modified, then the app crashes.
Now here comes the matter, CE automatically uses Software Breakpoints when it runs out of Hardware Breakpoints 4Max.
Then it writes 0xCC at each Breakpoint address, and makes the app crash.
I was wondering if there's any other method that doesn't write memory to Breakpoint an address, and be with unlimited usage.
P.S: I already tried VEH with debugProcess(2)...still using Software Breakpoints tho...
And also if you can solve me a doubt, i know CE API can handle AOBScanModule(), however LUA API can not... is going to be implemented Soon TM? 
Thanks.

try stealthedit and do the hooks in the copy
with lua you have access to the MemScan object, which also contains the aob type.

Gotta say you thanks. I'll explore stealthedit way.

Excuse me, how can i retrieve the new Memory Region Address that StealthEdit creates?
In CE MEM VIEWER simply look at the green opcodes, that points you to the copied address, but how to do it in LUA or ASM?

In asm you can use stealthedit (name,address)
Name will get the new address which you can use in the rest of the script (or with registersymbol)

Thanks for your quickness in asnwer DarkByte, but Name doesn't retrieve the address of the New region stealthedit creates...
| Code: |
local mew =([[
alloc(newmem,8);
stealthedit(newmem,0066FD80,2048)
label(returnhere)
registersymbol(newmem)
returnhere:
]])
autoAssemble(mew);
sleep(1000);
local result=getAddress("newmem")
--result=readInteger"newmem"
--unregisterSymbol("secopy")
print(result)
|
htp://puu.sh/kwQEK/f01cce1978.png (change it to http)
The output 2097152 = 001F0000 points me to an allocated region without data, when it should be 04AE0000
P.S: I'm using Stealthedit 2.3

Remove that alloc (newmem, line
If it's failing because registersymbol doesn't work then try something like
| Code: |
Label(xxx)
stealthedit(newmem,0066FD80,2048)
registersymbol(xxx)
newmem:
xxx:
