Fast food giant Burger King faced a social media nightmare yesterday after its Twitter account was hacked and its name changed to (main rival) McDonald’s.

“BURGER KING USA official Twitter account. Just got sold to McDonalds because the whopper flopped =[ FREEDOM IS FAILURE” read the account’s new bio, atop of a header picture displaying McDonald’s products.

Then ensued a string of anti-Burger King retweets and shout outs to well-known figures within the hacking community, leading many to believe that individuals affiliated with hacking collective Anonymous were responsible for the incident.

Burger King has since regained control of the account, light-heartedly tweeting: “Interesting day here at BURGER KING®, but we’re back! Welcome to our new followers. Hope you all stick around!”

The episode highlights the need for increased account security on Twitter, which currently consists of a single password log in system. Earlier this month the site revealed its plans to introduce ‘two-factor authentication’, which would require new log ins to enter a code sent separately to a mobile phone, thus preventing hacks such as this.
