What's the scale of the PHP cyber security flaw?

More than 50,000 UK organisations are being warned that they are vulnerable after a researcher using AI discovered a "critical security issue" in a globally-used programming language. Earlier on Thursday, a minister said more than thirty government services are offline and four are partially unavailable while work is being carried out to address the potential risk. National Cyber Security Centre (NCSC) experts are working with OpenAI, whose technology was used to discover the vulnerabilities, and partners around the globe to address potential problems, a No 10 spokeswoman said. • Subscribe
