Seventy percent of websites worldwide run on PHP, and recent vulnerabilities have been found in the language. This could potentially allow a server to be controlled remotely, prompting fears of cyber attacks. Twente and Fortuna are following the example of the Dutch Parliament, the National Cyber Security Centre, and news agency ANP. The clubs have announced through their channels that they have taken this precautionary measure. Twente states that their website, http://fctwente.nl, is expected to be available later in the day. Fortuna stresses that, so far, there are no indications that data has been leaked or that security incidents have occurred.
