Cybercriminals have reportedly increased their effectiveness by launching "multi-stage" attacks that combine messaging with other Web activities.
"[Criminal elements] have been forced to change their techniques to evade improved detection technology," Commtouch VP Asaf Greiner told TG Daily in an e-mailed statement.
"Complex multi-stage attacks with improved social engineering are proving to be the preferred technique."
According to Greiner, criminal elements exploit email and search engine results to lure victims to sites which host spam advertising, malware, or phishing.

"[Methods vary], such as leveraging trusted brands like Apple and Google; holidays, such as Mother's Day; or current events, for example, the Football World Cup."
