Description
W32/Blaster-G is a worm that uses the internet to exploit the DCOM
vulnerability in the RPC (Remote Procedure Call) service.
The worm will copy itself to the Windows system folder as eschlp.exe and
create the file svchosthlp.exe in the same location.
W32/Blaster-G creates the following registry entries to ensure it is run at
system logon:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Helper = <SYSTEM>\eschlp.exe /fstart
MSUpdate = <SYSTEM>\svchosthlp.exe
SPUpdate = <SYSTEM>\svchosthlp.exe
A more detailed description will be published here shortly.
Recovery
