nieuwsblad.be“Nog aanvallen op komst” na lek in programmeertaal PHPEn toen was er chaos. Zodra woensdag bleek dat er “kritieke kwetsbaarheden” waren gevonden in de veelgebruikte programmeertaal PHP, werden tal van websites en slimme toepassingen offline gehaald. Een oplossing is intussen voorhanden, al wil dat niet zeggen dat die al overal werd toegepast. “Gegarandeerd zullen er aanvallen komen.”

The #PHP flaw is patched, but not everywhere yet. Prof. Bart Preneel warns that #AI is exposing vulnerabilities much faster: “It may well be that we’ll have something like this every week for the next two years.” #CyberSecurity #PHP2Shell www.nieuwsblad.be/economie/tec...
