Spammers are known to be crowd chasers. And so it goes that social networking forums, sports events, and major news-generating events always seem to catch the spammers’ attention. In line with this trait, spammers are now targeting global expos. With around 70 to 100 million visitors expected to turn up at the Shanghai World Expo 2010 this year, spammers couldn't have asked for a better time to make their presence felt. Spammers are using the Shanghai expo in their subject lines and email messages to deliver fake promotions, sell products, and offer various services. Symantec has been monitoring several different variations of spam types in the campaign. Sample 1: Spammers include an expo event subject line to attract hits. In the body, there is a meds promotion URL right in the center and a bogus MSN subscription note at the bottom.
