Also, the study noted that malicious e-mail senders were using the 2008 Olympics in Beijing as a way to deceive recipients. Over the past six months, MessageLabs intercepted 13 different Olympic-themed attacks, spanning various industries. Twelve of the 13 attacks were sent from an IP address in Asia Pacific.
MessageLabs also observed a 419 scam (also known as the Nigerian money offer or advance fee fraud) that attempted to utilize a Linked-In profile to give its scheme the guise of authenticity. This was the first time MessageLabs had blocked this kind of scam, in which a professional social networking site was incorporated.
