Websites across world hit by millions of attempts to exploit PHP code flaw

Websites around the world have been hit by millions of attempts to exploit a recently discovered vulnerability in their code, cybersecurity companies have said, as the US National Security Agency warned the flaw could allow attackers to take control of web servers, steal data and disrupt services.

The problem in the PHP programming language, which underpins about 70% of the world’s websites, emerged on Wednesday causing governments and companies to pull their websites off the internet before they could be attacked and so they could patch the fault.
