Karen Gillan, the Scottish actress who plays the character of Amy Pond in BBC's "Doctor Who" TV series, has had her Twitter account compromised.
Almost a quarter of a million followers of the popular actress - who recently left the hit sci-fi show after being sent back in time by Weeping Angels - could be tricked into believing that she has found a way to lose weight that doesn't involve the Adipose.
Clicking on one of the links takes you to an all-too-familiar Acai Berry diet website, posing as a news story:
To fix a problem like this you don't need to reverse the polarity of the neutron flow, or even reach for your sonic screwdriver.
Simply change your Twitter password (ensuring that it's not easy to guess, and that you're not using it on multiple websites), and check what applications you have connected with your account (and revoke their access if required).
Furthermore, be careful that you only log into your Twitter account from a computer that is properly protected with up-to-date anti-virus software and security patches - in other words, maybe you shouldn't trust that computer in a hotel lobby or your friend's PC. Keylogging spyware can grab your password without you knowing, and pass it onto malicious hackers.
Karen Gillan isn't the only Doctor Who companion to have been involved in Twitter trouble. Jenna Louise-Coleman, who plays the mysterious Clara Oswin Oswald and replaced Gillan in the Christmas episode, was the subject of a sex video scam shortly after her appointment was announced.
It goes without saying that you shouldn't click on any links from Karen Gillan until her account is brought back under control.Follow @NakedSecurity
