PHP2Shell: The Internet Wasn't Broken. Something Underneath It Was.
There is something fascinating, and slightly unsettling, about the way the internet works. We tend to picture it as an enormous collection of independent systems, millions of websites spread across thousands of hosting providers and cloud platforms, built by countless developers using an almost endless combination of technologies. It feels distributed and resilient, and in many ways it is. Yet underneath all that diversity, a remarkable number of systems lean on the same few components, pieces of software that have quietly done their work for decades while we built ever more sophisticated things on top of them. Most days nobody gives them a thought. Then something happens that reminds us how much we depend on them.
