I’m wondering if anyone has a solution to blocking ULTRASURF on the PC - a VPN type program designed to bypass filters, etc. (it is also available as an EXTENSION for browsers such as Chrome, Edge, etc.)
I’ve discovered that this program, just over 3mb, which is simply an EXECTUABLE (.exe) can easily bypass Kaspersky Safe Kids.
I did attempt to raise a ticket with Kaspersky about the issue, but they asked me to do all sorts of things, which as a parent I simply haven’t the time or inclination to do. I’d expect their technical experts to do the necessary checks to overcome this vulnerability.
At any rate, It turns out that trying to block the Ultrasurf home page using Safe Kids, but it didn’t work.
Furthermore, a child can simply run this program from a USB stick, or copy it onto a PC from USB and it will run (no installation needed). I could not block the program via the Dashboard because, as it hasn’t run an installer, it doesn’t display as a program to be blocked!
Also, turns out, if you rename the file ‘usf.exe.’ to something else, it will still run - again, easily defeating Kaspersky Safe Kids (allowing access to everything).
So far, the only solution I have come up with is to block the home page and download page using Windows Host file. I’ve also had to password protect a firewall and require authorisation for files to access the internet - this means that if a child attempts to run the program, I will need to grant permission (input the password) to allow it to run - not an ideal solution.
Furthermore, I have set Kaspersky to block access to proxy and anonymizer sites, and yet sites offering ULTRASURF are still available. I’ve blocked access to sites that allow technology and software downloads, but still find that it’s possible to get downloads for this software, and others.
I’ve also tried using Windows 10 Pro Applocker to prevent this file from running, but without success (using HASH). It works when blocking using the name of the .exe, but the problem is that renaming the .exe (as mentioned above) will bypass that rule easily.
So, any suggestions as to how to block Ultrasurf would be appreciated, as well as for the developers of Kaspersky Safe Kids to come up with solutions to the problems I’ve highlighted (without expecting me to do all the work for them).
Finally, I have used the REGISTRY to block access to the CHROME (Ultrasurf) Extension, and also utilised an EXTENSION called BLOCKSITE to block the keyword ULTRASURF - setting a Password. Again, these things are not possible to do with Kaspersky Safe Kids currently.
