Hello Mydoom

When I disassembled the virus I found new information that haven't came up anywhere else to this time. Here is the information that is beleived... 1. use restricted usernames to send email to and from 2. encode strings with ROT13 method 3. create a mutex called 'SwebSipcSmtxSO' when ran 4. transform in taskmon.exe and 4.1 add [HKLM\Software\Microsoft\Windows\CurrentVersion\Run] "TaskMon" = %sysdir%\taskmon.exe 4.2 add [HKCU\Software\Microsoft\Windows\CurrentVersion\Run] "TaskMon" = %sysdir%\taskmon.exe 5. add %sysdir%\shimgapi.dll open ports 3127/tcp - 3198/tcp 6. stops spreading febuary 12 7. spreads through KaZaA and Electronic Mail System 8. and more very technical fact i will not describe here What I found... Even if the virus (Mydoom) is programmed in assembler and compiled using masm it is made to look like it has been programmed in C++ when disassembling. It is a fact that many more information are hidden and undiscovered to this date such as the fact that it will stop spreading on febuary 12 which is not true. Mydoom will pass in a new phase upon febuary 12 and it will be very much more serious as it will be updated and will mutate in Mydoom.C. The backdoor (shimgapi.dll) is open a port but this is used to obscur the real intention of Mydoom.B as well as Outlook express. It was also unknown that the virus infects the BIOS of the computer it infects by injecting a 624bytes backdoor written in FORTH which will open port tcp when Mydoom will be executed AFTER febuary 12. It is a conclusion that the viral professionals that published diagnosis of the Mydoom.A virus are trying to hide something or are very incompetent. Also there are no way to fix the virus that is injected in the BIOS after it has been infected except from flashing it AFTER disinfecting the workstation that was infected.
