ESET blocking Facebook Javascript from major Australian website


Recommended Posts

Hi there

Out of the blue on 23rd January 2017, ESET Smart Security 10.0.369.0 has started blocking Facebook Javascript from a major Australian website.
ESET virus signature database = 14813
This is a major news website, which I visit multiple times every day for over 10 years and then suddenly one element is being blocked.
Everytime I go to a different page on the same site, ESET pop-up is reporting Address has been blocked.

Website in question is:
hxxp://www.abc.net.au/news/

ESET logs report this:
Time;URL;Status;Application;User;IP address;Threat
23/01/2017 5:40:29 PM;https://connect.facebook.net/en_US/fbevents.js;Blocked by internal blacklist;C:\Program Files (x86)\Google\Chrome\Application\chrome.exe;ZEN\ArcAn;31.13.95.12;

Is this a false positive or a new threat that website in question needs to fix ?

Regards
Derek

I just started seeing this on quite a few pages, many being rather big sites like GreenManGaming.com, HumbleBundle.com, and Asus.com.  It seems to be happening on a lot of sites with Facebook follow/like links on them.  The Eset alerts actually stopped when I enabled the "Anti-Thirdparty social" filter list in uBlock Origin adblocker, which also points to the social links on these sites being the source of the detected malware.

Looking up a couple of the IP addresses listed in the Eset log shows that they are indeed owned by Facebook.  If anything is compromised, it seems that it's likely Facebook itself.  I'd definitely like to know if that's the case, or if it's just a false positive.

Hello,

there was indeed a FP, which has been already removed from the blacklist.

Installations with LiveGrid enabled should be able to access those sites already.

 

WE are sorry for the inconvenience.

Regards, P.R.
