Symantec researchers are warning that spammers have created their own services to shorten URLs.
"So far, some 87 URL shortening sites have been set up by spammers, said Nick Johnston, a senior software engineer at Symantec," writes Computerworld's Jeremy Kirk.
"Johnston said it is quite easy to block the shortened links, since many follow a consistent pattern, such as 3xy.info, and seem only to be used for spam," Kirk writes. "Since the shortening services don't appear be used legitimately, there's 'no risk of false positives by blocking them outright,' Johnston said."
