Sophos researcher Graham Cluley warned Tuesday that messages are also spreading virally exploiting the vulnerability without the consent of users (Related: Social media risks: The basics).

Thousands of Twitter accounts have posted messages exploiting the flaw. Victims include Sarah Brown, wife of the former British Prime Minister, said Cluley, who said Brown's Twitter page "has been messed with in an attempt to redirect visitors to a hardcore porn site based in Japan."

"It looks like many users are currently using the flaw for fun and games, but there is obviously the potential for cybercriminals to redirect users to third-party websites containing malicious code, or for spam advertising pop-ups to be displayed," Cluley said in a blog post.

"Hopefully Twitter will shut down this loophole as soon as possible," he noted.
