I have ran into a malicious ad, that once played automatically took my browser to a different site stating that my IP have been picked as a winner in a game that my internet provider is hosting. I've encountered it around 14:45-15:00 UTC +1/8:45-9:00 EDT on "https://www.nexusmod...skyrim/mods/141" the second time. First time I routinely closed the tab.
This has been a country wide problem in Hungary and started in the weekend and affected several bigger internet providers like Telekom, Digi, UPC and others. I personally use UPC. Several sites had banned the ads since then and even news sites reported on it too.

(if scrolled down, the above site has a gallery section on some examples the bad ad can produce)
Some of the ad destinations:
They would later point to a site like this:
Unfortunately I couldn't take a screencap of the ad, because it seems to be scripted to immediately take to one of it's destinations. If I can hunt it down I'll update the thread with a screencap of it.
Thank you in forward for the help!
