Earlier this year, cybersecurity researchers discovered a vulnerability in PHP, an open-source coding language used in roughly 70% of the world's websites, that had been lying dormant for a long time, and if exploited, could have led to disaster. And the researchers only understood the extent of this bug through the use of frontier AI models. Today, we talk to two staffers at Calif (CEO Thai Duong and engineer Bruce Dang), the cybersecurity firm that was among the first to discover the PHP vulnerability. Their firm partners with the major AI labs and neoclouds, and they help these companies test models and look for vulnerabilities in their infrastructure. Duong and Dang tell us how Calif uncovered the PHP hack, what the firm exactly sells, and what the future of cybersecurity looks like in the age of AI.
