After enough , security researcher Jerome Segura realized that the problem originates from Google's ad networks, DoubleClick and the popular Zedo. Both networks promoted malicious ads designed to distribute it Zemot malware. A representative of her Google confirmed the problem stating: "Our team is aware of the problem and has taken the necessary steps to eliminate it."

Malware served by ad networks (or "malvertising") is nothing new, but it is noteworthy because of the unusually wide scope of the attack.

“Ήταν ενεργό, αλλά δεν είναι ορατό για αρκετές εβδομάδες έως ότου αρχίσαμε να βλέπουμε δημοφιλή sites να “πετάνε” flags στα μας,” αναφέρει ο Segura.
"Then we thought something was wrong." "The first signs came in late August, and to date millions of computers may have been exposed to Zemot, and people with uninformed antivirus are at greater risk."

Zemot focuses on Windows XP computers, although it can also infect modern operating systems that run on x86 and 64bit. Zemot is designed to bypass the security of a system before it infects additional malware.
"Even if there were only 5% vulnerable systems," says Segura, "we expect a very large number of infections."
