Process Details :

                     Msblast.exe is the main component dropped by blaster worm. It exploits a vulnerability DCOM RPC [ Buffer Overrun In RPC Interface ] to infect target systems. The worm randomly scans for IP addresses [ X.X.X.0  Example: 202.124.64.0 ] and infects the vulnerable systems. This worm targets Windows NT, 2000, XP, and Windows Server 2003 systems. Solo Antivirus can detect and remove blaster worm and its variants safely.

                     Blaster worm copies to Windows System32 folder as msblast.exe and modifies the registry RUN section to load automatically. Then it scans other vulnerable systems and infects them. The registry modification is given below.

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
"windows auto update"= "msblast.exe"
