Malvertising campaigns have been discovered which utilise sophisticated "fingerprint" techniques to lead security researchers off the trail and only deliver payloads to legitimate victims.
Malvertising is the use of ad networks to serve unwitting visitors malware and exploit kits, including Angler and Neutrino. Many legitimate websites rely on advertising to generate revneue, and unfortunately, malware may slip through the net.
In 2015, the UK's Daily Mail became a host for malvertising, which served up to
156 million visitors with redirects to the Angler exploit kit. The vendor, however, isn't the issue: it is the security processes and checks of third-party ad networks which may permit malicious adverts to display without realizing it.
