one of the companies whose researchers uncovered the vulnerabilities &#8211; described the flaws as the &#8220;most severe&#8221; ever detected by AI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">OpenAI, whose technology was used to find the flaws, called the discovery &#8220;one of the most impactful security issues in recent memory&#8221;.<br>What is the flaw?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most people may not have heard of PHP, but they probably interact with it daily.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Short for PHP: Hypertext Preprocessor, it powers a vast number of platforms, including online shops, Wikipedia and WordPress \u2013 the content management system behind many websites like blogs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When you visit a website like Wikipedia, PHP is the code that collects information you need and presents it in a way you can read on the web, Paul Spain, chief executive of Gorilla Cyber Security, told the BBC.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But due to a flaw that could allow attackers to take control of affected web servers without authentication and steal sensitive data, everything built on PHP was left exposed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AI could make such attacks easier and faster, Spain said, estimating that the flaw could affect &#8220;millions and millions&#8221; of websites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It would be &#8220;disastrous&#8221; if hackers or countries weaponised the flaw and seized private data from websites, said cyber-security researcher Jill Slay from the University of Adelaide.<br>What websites have been affected?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The alert has disrupted services globally, from gaming platforms to government portals and online forums.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That includes Wikimedia &#8211; the organisation behind the online encyclopaedia Wikipedia &#8211; which took down a number of its systems as a precautionary measure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sites and pages have been taken offline by the Finnish government, Edinburgh council and the BBC, with the Netherlands&#8217; cyber-security agency also pulling its website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A number of Scotland&#8217;s public organisations, including councils and health boards, have also taken their websites offline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some experts warn the vulnerability could leave poorly maintained websites, particularly those belonging to smaller organisations with limited security resources, at greater risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More attempts to exploit these flaws are likely in the coming weeks since the technical details are now being made public, cyber-security researcher Salil Kanhere from UNSW Sydney said.<br>What happened after the flaws were exposed?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Developers of the PHP platform on Wednesday rolled out patches to fix the vulnerabilities that had been lurking in their software for years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;All PHP users are strongly encouraged to update immediately,&#8221; the company said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Authorities and security organisations around the world have echoed those warnings to website operators to secure their platforms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The US National Security Agency told all organisations that use PHP to take their systems offline if they were unable to patch them immediately, adding that the flaw could provide a &#8220;direct path&#8221; to exploit a system&#8217;s database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;These risks are serious enough to require immediate patching across United States Government departments and agencies,&#8221; the agency said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The UK&#8217;s National Cyber Security Centre gave similar advice and told organisations to check for &#8220;backdoors installed by an attacker&#8221;.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its counterparts in the EU, Singapore and Australia have also issued similar alerts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Japanese Prime Minister Sanae Takaichi urged people to check if their publicly available websites ran on PHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;We have an urgent request for everyone to take action tonight,&#8221; Takaichi wrote on X.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;If it is difficult to apply the fix patch promptly, temporarily suspending websites and similar measures can be considered an effective way to reduce risk,&#8221; she said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tech companies are also racing to secure their systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">E-commerce giant Amazon said it was targeted in multiple attempts days before the public disclosure of the PHP issue. It is unknown how the potential attackers knew about the vulnerability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How is AI finding weak spots?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The vulnerabilities were found by researchers at the security firms Calif and Wiz.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The researchers used advanced AI tools that are able to analyse code and find flaws much faster than humans or older systems can.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Modern software is incredibly complex, and some vulnerabilities can remain undetected for years,&#8221; Kanhere said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The underlying bugs weren&#8217;t new; what changed was our ability to find them,&#8221; Kanhere said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Details of the discovery leaked online this week, forcing the PHP platform&#8217;s developers to rush out its announcement of the security flaw and its huge scale.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The incident &#8220;highlights how AI can uncover security flaws&#8221; but also how it can &#8220;help attackers rapidly develop offensive tools and exploits,&#8221; OpenAI said in a blog post.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ChatGPT-maker said it had released a program to check if the PHP platform is secure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Many of these flaws stem from the way software were built in the past, which were built for functionality and not with security in mind,&#8221; said Ryan Ko, at the University of Queensland&#8217;s Cyber Research Centre.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What can people do to safeguard themselves?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Website owners are being urged to secure their websites with the latest version of PHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The PHP software patch is a small, routine fix for most tech teams, Spain said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The US National Security Agency has urged &#8220;heightened awareness&#8221; in the coming weeks and to closely monitor updates from software vendors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Vigilance in applying patches related to those systems is paramount,&#8221; it said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The onus lies mainly on website operators, but users should stay alert for any security advice issued by affected services, such as requests to change passwords, Kanhere said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">He warned people to be alert to any phishing messages exploiting the publicity around the incident too.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.bbc.co.uk\/news\/articles\/cmly0lg3w5x2o\" target=\"_blank\" rel=\"noopener noreferrer\">More &gt;&gt;&gt;<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For more than a decade, serious flaws had gone undetected in the technology underpinning much of the internet.
