So, why is a shortened URL in a spam email so much of a threat? Well, as MessageLabs warns, the website in the URL you’re directed to may not, in fact, be what you think it is, and may just be a trick to lead you right into trouble. The shortened URL, it seems, allows spammers to hide the real web address they’re sending you to. MessageLabs’ Paul Wood says there are literally dozens of websites that offer URL shortening services and spammers have realised that using these services “eliminates the need to solve a CAPTCHA or register an account.” Wood also says that, with many social networking sites providing character restrictions on status updates and messages, the use of free URL redirection services which turn lengthy web addresses into shortened URLs is increasing in popularity with spammers for multiple reasons. He points out, for instance, that the newly shortened URLs help cybercriminals disguise the true destination of where their victims will click through to, posing further risks of entering websites used to conducting drive-by malware attacks as well as spam. “Donbot, the botnet responsible for sending approximately five billion spam messages every day, is one of the main culprits for using this technique. Links of any size all need to be treated with caution,” warns Wood. |
