Cyber criminals are reportedly turning to Twitter to target their latest victims.
They are launching attacks hidden in "tweets" and tiny URL addresses, according to internet security group McAfee.
It claims that the accounts of celebrities such as Britney Spears, politicians including President Barack Obama and even Twitter itself have been hacked on multiple occasions.
More than 14 million computers have been hacked into this quarter, says McAfee, a 16 percent increase over last quarter's rise — meaning an average of 150,000 are infected every day.
Twitter's growth in popularity has made it a new target for the cyber criminals.
Facebook and MySpace, meanwhile, remain strong attack targets for web hackers.
"Cyber criminals are like traditional criminals in that they want to make money," McAfee's security analyst Greg Day told Sky News Online.
