Folks just need to compromise these massive ad server farms now even legit sites are now attack points for your computer. It also helps load webpages faster. If you are blocking the ads you don’t have to wait for the ad servers to load their ads because sometimes the ad farms get taken down internally due to issues as well..
Earlier today, we warned people that both The Times of Israel and The Jerusalem Post were affected by a malvertising attack.
It appears that this is a much larger and ongoing campaign that is affecting a number of other popular websites.
The reason this is really big is because it involves doubleclick.net (a subsidiary of Google for online ads) and Zedo (a popular advertising agency).
