Win32.Worm.Downadup Removal Tool 1.22 Description:

The Anti-Downadup application was designed to be a virus removal tool that searches for Downadup service in possible infected items.

Win32.Worm.Downadup is a worm that relies on the Microsoft Windows Server Service RPC Handling Remote Code Execution Vulnerability (MS08-67) in order to spread on other computers in the local network. The authors took various approaches to make this malware especially fast spreading and hard to remove.

This malware always comes wrapped in an obfuscated layer which aims at deterring analysis. The layer can be in two flavors, either packed with UPX or not packed, but it is always obfuscated and uses various rarely used apis to break emulators. The real malware is contained inside in an encrypted form. It is packed with a standard upx version, but to deter unpacking it is never written on disk and it doesn't have the PE header which makes it appear as an invalid executable. This has the side effect of being undetectable when injected into another process, it just looks as standard memory allocated page.

A computer can be infected by possible three means:
* if not patched with the latest security updates (in this case if MS08-67 vulnerability is not patched), by an already infected computer in the local network
* if the administrator account of the computer has a weak password (brute force dictionary attack against administrator password is used)
* if the computer has the Autoplay feature enabled and an infected mapped/removable drive stick is attached.

Once gained execution this worm does the following actions:
* hooks NtQueryInformationProcess from ntdll.dll inside the running process
* creates a named Mutex based on the computer name
* injects intself into one of the following processes:
* explorer.exe
* svchost.exe
