Hm, ovo pišem jer sam prije nekoliko dana uspješno napravio jedan "Revenge" program u VB.

Zašto hide process : Tako da proces nije vidan u TaskManager-u oz. kad stisnete Ctrl-Alt-Del.

Ovo pišem jer je došlo do nekompatibilnosti sa NT sustavom NT/2000/XP, jer naime program na NT mašinama ne nađe reference za RegisterServiceProcess u kernel32.dll, jer RegisterServiceProcess u NT-jima u kernel32.dll nema.

Gledao sam malo po searcherima, MSDN a nisam ništa našao. kako bi rješio ovo "nekompatibilnost" OS-a.
Kako bi na drug način to riješio u NT-jima.

Evo još malog koda, kog treba da malo modificiram za NT-je :

Code:

Public Declare Function GetCurrentProcessId Lib "kernel32" () As Long
Public Declare Function GetCurrentProcess Lib "kernel32" () As Long
Public Declare Function RegisterServiceProcess Lib "kernel32" (ByVal dwProcessId As Long, ByVal dwType As Long) As Long
Public Const Make_System_Process = 1
Public Const Make_Normal_Process = 0

Public Sub HideProcess(HideProcess As Boolean)
'HideProcess(true)
'HideProcess(false)

Dim Process_Code As Long, Return_Service As Long

If HideProcess Then
Process_Code = GetCurrentProcessId()
Return_Service = RegisterServiceProcess(Process_Code, Make_System_Process)

ElseIf Not HideProcess Then
Process_Code = GetCurrentProcessId()
Return_Service = RegisterServiceProcess(Process_Code, Make_Normal_Process)
End If
End Sub

Help wanted, poz

Jel ovo da nije vidljiv znaci da nije vidljiv na Applications (ili kako se vec zove polje u tab-u) ili da nije uopste vidljiv ni na Processes polju?

Registriranje service procesa na NT je malo zajebaniej nego na win9x. Tamo imas samo jedan API (RegisterServiceProcess), a na NT imas citavu proceduru: StartServiceCtrlDispatcher(), RegisterServiceCtrlHandler(), SetServiceStatus(), CloseServiceHandle() pa na OpenSCManager(), OpenService(), CreateService() i CloseServiceHandle(). Vidi MSDN za detalje. Sakrivanje procesa iz liste procesa se dakle moze lako ostvariti strvaranjem service procesa. Medjutim, proces ce se i dalje moci vidjeti preko toolhel32 funkcija za enumeriranje procesa (Pview95.exe koji dolazi sa Visual c++ to koristi npr.). Sakrivanje iz te liste bi zahtijevalo hookiranje nekih API-ja, a za to ti treba asm.

A jeli. U VB? Provjeri da li ti ga ovi alati detektiraju:

http://www.sysinternals.com/files/procexpnt.zip <- za winNT/win2k

Da, znam da je CAD opcija u M$ OS-ima dio OS i naravno ovaj program "vidi" sve apliakcije/threade koji su trenutno aktivni i oni "nevidni" sistemski, no uspijelo mi je da se program ne vidi kao aplikacija/proces kod CAD, a sada trebam još kodu za NT, kako onemogučiti CAD shortcut sa tipkama, u 9x je to easy u NT-jima ... mislim malo teže ...

Da znaš riješio sam još 2 veoma dobra programska puzzlea !!

Naučio sam nešto o ASM i disasemblanju ... moram reči, da je to nešto veoma dobro i poučno, počeo sam se baviti i sa VB malo bolje.

No onaj 2 exe problema kojeg sam ti poslao pa mailu još me stalno prati, pa te molim, dali ti je težko da mi napišeš što zapravo radi onaj (kako) source code, jer vidio sam, da ima unutra još jedan string "H4ck3d4ndCr4ck3d", što točno ne znam šta se sa njim događa jer ne znam C, dali bi bio tako dobar pa barem napišeš kako dođe do enkripcije, jer ja sam se uputio u samu enkripciju i u headere PCX grafičkog file-a.

pa i onaj puzz4.exe je jako (barem to ja mislim) strašan, uspijelo mi je da skužim "šta" radi, ali ne znam kako bi došao do prave sequencije odgovora zbog "the merory could not be read", probao sam se malo igrati i u w9x, no došao sam do zaključka, barem mislim, da je to moguče i zbog različitih OS-a.

Sa RCx8 processorom imam jadnih problema kod I/O portova !!!

Kao prvo, 9x ne podrzava sistemske service, to je samo improvizacija.
a i kad pod NT registiras servis ipak taj isti postoji u Listi procesa
samo sto ne mozes da ga kill-ujes.

Na NT ne mozes sakriti proces !!!

e sad da se malo sam demantujem, ipak je moguce, ali to je samo workaround, a nije pravo sakrivanje procesam, vec ubacivanje stranog koda u vec postojeceg procesa. Za detalje pogledaj source BO2K, a ukratko to se radi uz CreateRemoteThread(), vidi ovaj link sa source kodom za VC6 http://www.mvps.org/win32/processes/remthread.html

Improvizacija ili ne, RegisterServiceProcess() funkcionira.

Injektiranje u adresni prostor drugog programa je stara fora. Samo da kazem da ga koristi i WMFA ICQ trojan (iako ne na gore opisani nacin).

These worms all have one thing in common: They use Microsoft Outlook to send email to all contacts in the Microsoft Outlook address book. Some variants also try to delete files or send themselves to IRC users.

Ali pogledao sam malo, zanimljivo ...

WinNT/2K/XP STEALTHER UTILITY v1.02
-----------------------------------

When executed on target machine (system or administrator rights required),
this program will copy itself to %SystemDirectory% as RPCXSS.EXE,
and create/start itself as system service.
This service will perform the following actions:

1. Stealth RPCX* files in the:

- taskmanager
- system service manager
- findfirst/findnext
- registry

2. Stealth in netstat by port 31337, TCP/UDP

3. Each second this service will check for new RPCX*.EXE files
in the %SystemRoot%\system32\ (except RPCXSS.EXE itself),
and execute them under SYSTEM privileges, once per session.

As such, to execute stealth processes on the target machine, you only
need to start there this program (dont forget to delete original file),
and then to put your own programs as RPCX*.EXE files into system32 directory.

3. Command line parameters

/yo passphrase, used to install/uninstall,
otherwise will work only as auto-executed service

/report show user name; then
show ++ if installed,
show -- if uninstalled,
or E1..E12 if error

KNOWN BUGS:

v1.02
- registry/netstat stealth doesnt works in NT4,
file stealth works partially in NT4
