The U.S., Russia and China are the top three sources of spam around the world in June, says the new report from Kaspersky Lab.
While the U.S contributed for 13.2 percent of the spam, Russia accounted for 7 percent and China contributed 5.6 percent of the total spam share.

Trojan-Spy.HTML.Fraud.gen again topped the list in the list of malware spread by email. Trojan-Downloader.MSWord.Agent.z was in second place.
With FIFA World Cup run-up, phishers attempted to dupe users by asking them to participate in competition to win tickets.
Also, Nigerianscammers exploited the situation in Ukraine and asked for help to transfer non-existent millions.
Among the websites, email search sites (32.1 percent) again topped the rating of organizations most frequently attacked, dropping by 0.2 percentage points; followed by social networks (27.7 percent), with an increase of 3.7 percentage points compared to May.
