In a continuation to the previous post about a computer with “infected” DNS settings….
The same machine also had a Proxy PAC file set.
In the specific computers instance it had this URL set in the automatic proxy settings section:
http://stoppblock.net/wpad.dat?fb4c39d90b3dd1f76bda246b4a60839913671305
stoppblock.net, registered via a whois privacy service, was only registered on the 4th July 2016 and has only been hosting a website from around the 21st July. A similar domain “Stopblock.me” seems to have been registered much longer ago in September 2015 using a privacy service and a similar DNS setup to the new site and is hosted at the same datacenter.
Now – if you download the above URL using something like Notepad or CURL you get a blank file telling software to go DIRECT;
If you use a known browser you instead get the following PAC script found at the end of this blog article.
What is interesting here is they seem to be taking SHA256 hashes of URLs and matching them. Clever idea. This instantly increases the difficulty in identifying which websites they are targeting with their proxy attack.
It looks like they are usurping traffic to 192 domains.
If one of these domains is detected they then currently relay the traffic via the following proxy hosted at FDC Servers:
50.7.182.141:51598
It looks like the above server has thousands of open ports, probably all entirely open and ready to proxy.
If you manually set your proxy to it you can tell which websites are on their intercept list in the PAC file. Any domain they don’t like is greeted with a “403 Forbidden” while domains they do like.. (some that I’ve found so far):
– Google.com
– chrome.google.com
– http://www.google-analytics.com
The above sites get proxied and SSL Man in the middled (MITM). I feel like maybe the malware which setup this PAC comes along with it’s own “Trusted” Root CA so their generated proxy certificates work.
Upon initial investigation the root of google.com doesn’t get modified upon request via the malware proxy.
Here is the proxy PAC code as referenced above.. it was too long to put in the middle of the article:
