A New Wave of Bad Ads Is Hijacking Even Top-Tier Websites (2018)

“Over the past two years, we have seen the amount of malware and mobile redirects, which might lead to malware, roughly double in the digital ad ecosystem,” says Chris Olson, CEO of The Media Trust, a McLean, Virginia company that provides security services to ad providers and online publishers. The exact content users see depends on who they are, where they are, what kinds of devices they’re running and other characteristics, making it difficult for publishers and ad networks to conclusively review every version of an ad for malicious content. And experts say the problem traditionally gets worse around the year-end holidays, when the number of online ads skyrockets just as the people able to review security issues at ad networks and publishers are on vacation or occupied with other matters.
