US is the second biggest distributor of junk mail in the month
The share of spam in email traffic was up by 2.2% in April compared to 77.2% averaged in March, according to findings from Kaspersky Lab’s latest report on spammer activity.
In April, some major changes were identified in the geographical distribution of spam sources, with the most evident one being an increase in spam originating in the US that saw it jump 18 places, as the second biggest distributor of junk mail in the month.
The share of spam emanating in email traffic from China also increased by 5% and the country is now ranked fifth among the world’s top sources of spam.
The proportion of unwanted correspondence from Indonesia dropped by 5.2%, which made the country fall 10 places and ending at 12th place.
Kaspersky Lab senior spam analyst Maria Namestnikova said in the months to come, the company expects a return of the all-too-familiar spam mailings with scandalous news items about current US President Barack Obama.
"Furthermore, phishing attacks will likely focus more on social networking sites, and possibly online games — as summer vacation is upon us, students on break from school will be more active online," Maria added.
"While these users tend not to have bank accounts, they do spend a lot of time on social networks and other online entertainment."
Kaspersky Lab detected a mass spam mailing in April that at first glance mimicked like an official Facebook notification, for a new friend request, where the links in the messages took the users to infected pages on Wikipedia and Amazon.
Other phishing emails appeared in spam traffic of gamers awaiting to play a beta version of Diablo III, for which they were asked for their battle.net account information, though the link in the email lead to a phishing webpage, not the original.
Primarily targeting US and French readers, political spam came into action in April, with frequent mentions of Barack Obama in spam emails "exposing his political course" and advertising a variety of traditional spammer products.
The European football championships, the Summer Olympics in London will also be exploited by scammers who will trick email users announcing lottery wins.
