The infected mail sample is given below

                     When the worm file is executed, it copies itself to Windows folder as "EasyAV.exe". Netsky.T modifies registry run section to load automatically on the next startup. The registry modification is given below.

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
"EasyAV"= %WINDOWS%\EasyAV.exe

[ By default, %WINDOWS% will be C:\Windows in case of Windows 95/98/ME/XP, C:\Winnt in case of Windows NT/2000 ]

                    Netsky.T worm uses its own SMTP engine to send infected messages. The worm also removes registry entries created by Mydoom.A and Mydoom.B worm. It opens port 6789 to allow access to the infected system.
