Twitter not as secure as other sites
The fast-growing microblogging site Twitter has fallen behind some other internet services in introducing tools to help secure the accounts of users, security experts say.
Weaknesses in Twitter's security became apparent on the July 4 Independence holiday as an unknown hacker took control of a Fox News Twitter account and sent out messages falsely claiming that President Barack Obama was dead.
While the hijacking of Twitter accounts is not new, the false Tweets about Obama generated headlines around the world. The Secret Service is investigating the matter. Fox News has said it is unsure how the attacker gained control of its account, but complained that it took Twitter more than five hours to return control of the account to Fox.
