In yet another high profile social media attack earlier this week, hackers took over Selena Gomez's Instagram account to post nude pictures of Justin Bieber, her former boyfriend, to her 125 million followers.  Five days on, Instagram has now admitted that a bug in its application programming interface was to blame.  Even more worryingly, the bug is also believed to have given the hackers access to private phone numbers and email addresses.

It seems this was a targeted attack on high profile celebrity users of the social media site, but remains a reminder to all social media users to take steps to secure their accounts.  Strong and unique passwords are the minimum, with two factor authentication and up to date security software recommended by computer experts to keep private information secure.
