Spammers Love Short URLs
Symantec's July 2010 MessageLabs Intelligence report finds that the percentage of spam containing shortened hyperlinks has increased significantly over the past year.
Symantec has released its July 2010 MessageLabs Intelligence report, which finds that the percentage of spam containing shortened hyperlinks has increased significantly over the past year. At its peak in April 2010, 18 percent of all spam contained shortened URLs, almost double the previous year's peak in July 2009 when 9.3 percent of spam contained shortened hyperlinks.
"As far as spammers are concerned, any tactics that make it harder to block their spam emails are going to be exploited," says company senior analyst Paul Wood. "When spammers include a shortened URL in spam messages, these shortened hyperlinks contain reputable and legitimate domains, making it harder for traditional anti-spam filters to identify the messages as spam based on the reputation of the domains found in the spam emails."
