The hoax which saw Twitter's shares spike on Tuesday might have looked convincing to some, but web experts told CNBC that such a ploy is actually fairly simple to pull off.
Shares in the social media company jumped after a (fake) story suggesting that Twitter had received a $31 billion takeover bid was published on a (fake) Bloomberg website -- Bloomberg.market rather than Bloomberg.com.
A Bloomberg spokesperson quickly moved to confirm the story was fake on Tuesday, and was not affiliated with the financial news company's site.
But Fintan Lambe, managing director of Popcorn Web Design Limited, explained that a hoax like this was actually "very simple." It requires only a small amount of website-design knowledge because the source code – the coding behind a website – is openly available.
"If you can see a website, you can steal it," Lambe told CNBC by phone. "All they would have had to do is open the Bloomberg website and cut and paste the code," thereby creating a replica website, he added.
