It may be a new worm/virus. See the symptoms below.

http://vil.nai.com/vil/content/v_100559.htm

Virus Characteristics: 

This detection is for another virus that exploits the the MS03-026
vulnerability.

It is not related to the W32/Lovsan.worm.d variant described here.

The virus is detected by the current Daily DATs as Exploit-DcomRpc virus
(with scanning of compressed files enabled).

Preliminary Analysis

Initial analysis shows the virus to install within a WINS directory
which is created in the Windows System directory:
C:\WINNT\SYSTEM32\WINS\DLLHOST.EXE (10,240 bytes) 

Strings within the virus suggest it copies the TCP/IP trivial file
transfer daemon (TFTPD.EXE) binary from the dllcache on the victim
machine to this directory also, renaming it:
C:\WINNT\SYSTEM32\WINS\SVCHOST.EXE 

The following services are installed: 
RpcPatch Set to run the installed copy of the worm (DLLHOST.EXE) 

Display name: "WINS Client"
RpcTftpd Set to run the copy of the TFTPD application (SVCHOST.EXE) 

Display name: Network Connections Sharing

Analysis is currently ongoing - description will be updated once
complete.

Hi,

We do have the same problem. Incidents.org has recorded the same
(http://isc.incidents.org/) but not much detail available.

Thanks,

Antony Abraham

Frank,

Yes, exactly, our ICMP requests are also detected as Cyber kit 2.2

Seems we share the same problem.

Some others too?
