 Posted: Sat May 02, 2015 9:19 am Post subject: auto scan and pause the process(new question) |
 |
|
hi everyone,I want to dump some decrypted file content from memory.(these files are encrypted,only decrypt in memory).but these file content only show 0.5s in memory,then I can't find them anymore.pausing the process works,but I only succeed 5 times(I tried 100 times +)  so I wonder if someone write a script for me,make cheatengine scan these array of bytes automatically,and if these array of bytes are found,then stop the process,so I can dump the memory.I don't know if it is possible.
What I think I need are:
1.freeze the process.
2.scan for : 01 00 00 00 00 00 45 4E 43 53
3.if these are found,just keep the process pausing.if not,unlock the process,and freeze it after 20ms,then scan these arrary of bytes again.
damn,I know these descriptions are bad,but I really need some help.thanks!

| Code: | timer.createTimer(nil)
timer.Interval = 20
timer.OnTimer = function(timer)
pause()
local aob = AOBScan("YOUR_AOB")
if aob.Count > 0 then
timer.Enabled = false
print(aob[0])
else
unpause()
end
aob.Destroy()
aob = nil
end
timer.Enabled = true |

Not all situation is tested. For instance, 1st scan is already success in my example.
It seems auto-attach function only when ce not already attached to any process (reasonable).
| Code: | function pulseScan(aob,procname,doResult,interval,maxscan)
interval = type(interval)=='number' and interval or 25 -- milisec
maxscan = type(maxscan)=='number' and maxscan or 20 -- scan is slow , 20 scans can take up some mins
doResult = type(doResult)=='function' and doResult or print
local Result,errmsg,cntscan = nil,'timeout',0 -- function end if result get a number value or maxscan reached
local function cemerge(t,o) for k,v in pairs(o) do t[k]=v end return t end
local ms = cemerge(createMemScan(),{OnlyOneResult=true})
local function callLater(d,f,...)
local t,a,n = cemerge(createTimer(),{Interval=d,Enabled=true}),{...},select('#',...)
t.OnTimer = function(sender) sender.Destroy() f(unpack(a,1,n)) end
return t
end
local function scan()
cntscan = cntscan + 1
print('scanning #',cntscan,' at ',os.date('%X'))
pause()
ms.newScan()
ms.firstScan(soExactValue,vtByteArray,rtRounded,aob,'',0,0x7fffffffffffffff,'',fsmNotAligned,'1',true,false,false,false)
ms.waitTillDone()
unpause()
if ms.Result == nil and cntscan < maxscan then
callLater(interval,scan) --- no result scan again
else
if ms.Result == nil then -- timeout
callLater(1,doResult,nil,errmsg)
else -- found result
callLater(1,doResult,ms.Result)
end
ms.Destroy()
---- exit pulseScan here, since not calling scan any more
end
end
getAutoAttachList().Text = procname
--- AutoAttach ONLY when CE not already attach any process
onOpenProcess = function(pid)
local targetpid = getProcessIDFromProcessName(procname)
if pid == targetpid then
callLater(1,scan)
onOpenProcess = nil
end
end
end
--- test: open a cheat engine ct file with notepad.exe
pulseScan('40 00 68 00 65 00 61 00 74 00 45 00 6e' , [[notepad.exe]], function(result,msg)
if result ~= nil then --- can pause again here
print(string.format('found > %08X',result))
--[[ -- save memory content around result address... not tested
pause()
local f = io.open('save','wb')
f.write(readString(result-0x1000,0x2000) -- ???
f.close()
unpause()

else
print(msg) -- err

no, only milliseconds.
you could use createNativeThread and run the code in an infinite loop, but you would probably not see any difference, as the scan already takes longer than 20 milliseconds

thank you,i see.when I set the interval to 1 ms,some content still went missing.well,do you know if there is another software can do this(pause the process then unlock it after some microseconds)for me?thanks! |
