Hi. Please tell us also the ports used for these attacks.
Thanks,
Bill

Subject: Serious Offshore Probes Detected & Defeated

We have had 11 extremely serious probes/attacks in the past 4 days on our "honey pot" and Shadow successfully detected 
and stopped all of the probes/attacks.  


Extremely serious is defined as two conditions; 

(1) Continuous communications (either UDP or TCP) being received for more than 4 hours from each IP address below.

(2) An IP address that sent communications (TCP, UDP, or RAW), then stopped communications and restarted the 
communications, continuously within a 12 hour period.


We have provided information that is very detailed information where we have successfully traced the Point-Of-Origin of 
the probes/attacks from China and other non-US locations


BACKGROUND

We are a Cyber Security Software firm and have been probed by offshore interests quite often since our genesis.  


We have established a honey pot site on the Internet.  


Using the Shadow Security Suite (our product) as the (only) security solution active on the web server/network, we have 
successfully detected and stopped the probes/attacks and traced the probes/attacks back to China and other non-US 
locations. 


DETAILS

(1) There are seven active sites in China:


221.209.110.50 - CNCGROUP Heilongjiang province network -Mudanjiang

116.18.161.55  - ChinaNet Guangdong Province Network - Guangzhou

219.148.119.2  - Data Communication Division - Beijing

221.208.208.3  - CNCGROUP Heilongjiang province network - Mudanjiang

121.18.13.107  - CNC Group Hebei province network - Hebei

125.76.238.164 - CHINANET Shanxi(SN) province network - Beijing 

218.3.134.250  - Data Communication Division, Network Center of Fast China Shipbuilding institute - Zhenjiang


Of the seven sites listed above, 121.18.13.107 has attempted the most intense attack, installing Remote Access Java 
Scripts as defined in my previous e-mail on detecting the China attack methods.  None of the seven sites above were 
successful against Shadow. All probes/attacks were detected and stopped.


(2) Shadow has been detecting and securing our web site/network from 5 simultaneous probes/attacks from China, each 
from a different city in China.


(3) We have been able to determine, the probes/attacks are evolving to a very advanced methodology, which no longer 
depends on a successful ping (ICMP), and now start with a defined IP address, and cycles through every possible IP 
combination within the IP address range.  As an example, a probe starts with "100.100.100.001", launches a UDP packet 
and/or TCP packet, then goes to "100.100.100.002", then "100.100.100.003", so forth and so on.


(4) The other probes/attacks were from the following:


219.240.44.147 - Hanaro Telecom Co. - South Korea - Seocho

138.79.215.61  - CPSOFT - Australia - No City Identified

81.188.3.50    - Easynet Belgium, Cypres - Belgium - Brussel

24.64.132.11   - Shaw Communications - Canada - No City Identified



IMMEDIATE RECOMMENDATION

------------------------


1) Immediately block the following IP Addresses within your network firewall(s) (This is a temporary fix since these IP 
addresses will change on a high frequency):


121.18.13.107  <-- Most Dangerous Attack

221.209.110.50

116.18.161.55

219.148.119.2

221.208.208.3


2) If Shadow is not installed on a Microsoft server, turn off (disable) java scripting immediately.
