W32/Blaster-G

[Marianna]

Type
Win32 worm

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.
