Last night, researchers at Malwarebytes noticed strange behavior on sites like , The Times of Israel and TheJerusalem Post.
Ads on the sites were being unusually aggressive, setting off anti-virus warnings and raising flags in a number of Malwarebytes systems.
After some digging, researcher Jerome Segura realized the problem was coming from Google’s DoubleClick ad servers and the popular Zedo ad agency.
Together, they wereserving up malicious ads designed to spreadthe recently identified Zemot malware.
A Google representative has confirmed the breach, saying “our team isaware of this and has taken steps to shut this down.”
