Russia is the most spammed in May with a spam rate of 82.2%; in UK 75.4% of email was spam
The UK had the highest ratio of malicious emails in May, as one in 91.7 emails was blocked as malicious, according to a new report by Symantec.
A new report by the security company said that in May, spam increased by 2.9 percentage points with spammers establishing their own fake URL-shortening services to perform URL redirection.
The MessageLabs Intelligence report identified that shortened links created on the fake URL-shortening sites are not included directly in spam messages. Instead, the spam emails contain shortened URLs created on legitimate URL-shortening sites.
These shortened URLs lead to a shortened-URL on the spammer's fake URL-shortening website, which in turn redirects to the spammer's own website.The unique thing about the new URL-shortening sites is that the spammers are treating them as 'stepping stones' - a link between public URL-shortening services and the spammers' own sites.
"However, as long as new URL-shortening services are being created, we expect spammers to continue abusing them." The report also said that the most frequently blocked malware targeting endpoint devices for the last month was the W32.Ramnit!html, a worm that spreads through removable drives and by infecting executable files.
Phishing activity decreased by 0.06 percentage points compared to April, with 1 in 286.7 emails registering phishing activity. Analysis of Web security activity showed that approximately 3,142 Web sites each day were harbouring malware and other potentially unwanted programs including spyware and adware, an increase of 30.4% since April 2011.
