The Most Detailed Way To Block UltraSurf  

Jun 05, 2009 10:47 AM

Here is the step by step process to disable Ultra Surf from being accessed by your clients.

To start with, Ultra Surf leaves a finger print that shall be needed by the admin as a constant value. It is very fortunate that the fingerprint is also included when you open the Ultra Surf. Listed below are the different fingerprints for the Ultra Surf variants available in the web namely:

1. UltraSurf 9.4 (.exe)
md5: 11bc744801b516d0b84fba5850ec8789

2. UltraSurf 9.4(.zip)
md5: 8aed5412df0f621e399c78a7f408c6fb

3. UltraSurf 9.2 (.exe)

4. UltraSurf 8.9 (.exe)

5. UltraSurf 8.8 (.exe)

6. Firefox add-on (.zip)
md5: 6ce151b1b0ef8430031a8e9a69f38806

We have to log in as a full administrator to the SEPM console and proceed first to the group that you will initiate the policy to. Under the policies tab, we must go to the “application and device control policy” that is found within the location specific policies.

Proceed to the application control and click on block applications from running. We could also put the enabled rule set as production or test only. It is advisable to set it first on test mode first and check later if the process was successful.

Edit the “block applications from running” rule and create a “Lunch process attempts” sub-rule under the “Block applications from running”. Click the add button under the “apply to the following process”. Click options to see the “Match the file fingerprint” and from their put the Ultra Surf MD5 on the space provided and click OK. When you are in front of the “Edit Application Control Set” page, click on the actions tab to choose among the following options that we administrators could use as an action namely:

1. Continue processing other rules
2. Allow access
3. Block access
4. Terminate process

We could also use the send the user a message option so that they would also be aware that they are being monitored thus intimidating them to use or access Ultra Surf in the near future.

Always remember the following after placing new policies in the specified computer groups:

1. Update contents needs to be pushed to the client group
2. We could also pull the update policy from the client
3. Better to reboot the computer for the updates to set
4. Verify if the policy serial number for the group is the same with the computers SEP policy number
5. Test if the policy is now working by checking the log via Truscan Proactive Threat Scan
6. Please note that if you put the enable rule set to test only, Ultra Surf might work but it will be logged via Logs under “Application and Device Control”
7. Enforce also any project to a small group of computers before implementing globally to the whole organization
8. Always do documentations for review
9. Always check for new fingerprints if new UltraSurf versions are available

Lastly, UltaSurf is not a bad application since it is used in the mainland China to have the freedom to be informed specifically about the outside world. It becomes a liability if they are using it to violate company rules that make a breech in the system for viruses to infect the computers they are using as well as others. I hope that this would help other administrators to block UltraSurf from being used.

I would also like to thank mon_raralio and trusted advisor RickJDS for all the valuable help and guidance.  
This is just my simple way to repay their goodness by making this article to help others.
Thank you all...

You need to unzip the file first.  Then import the extracted .dat file into SEPM under the Application Control policy.

May 29, 2014 04:05 PM

Hello Elisha. I'm having trouble import the policy into my 12.1.4023.4080 SEPM. do I need anything other than the .dat file and admin rights for the server? Thanks for a reply.

May 02, 2013 03:10 AM

Hello Elisha.

Thank for your policy file. It work great. Well done, we dont need to hand input MD5 every time.

Thank you.

Hello, how can I find the current ultrasurf.exe fingerprints? I need to u1210.exe fingerprint, thanks.

Feb 07, 2013 10:08 PM

Rather than using a hash, I created an Application Control policy that will block Ultrasurf from running, no matter what version it is.  I have attached the policy.  You can simply import this into SEPM and then assign it to the group you want to block Ultrasurf.

is there a way we can delete though SEP, Blocked ultrausrf files. We have files all over.

Thank you

I have configured Application & Device control as detailed in the above article, and the proxies are blocked , but the user notification pop up were not working(eg : WARNING: You are added to the list of monitored users, Ultra Surf is Blocked ), while I am trying to run the proxi.

Please do help me to resolve this issue..

you can find huge list of proxy site in link below;

but blocking all of them may not be feasible; thus what is practcal is to block those proxies that are being used widely in your network

Jun 09, 2009 04:14 PM

i also agree with you on this;

waiting for blocking of more proxies and those finger print
