In the cloud, researchers revealed a more subtle but equally dangerous vulnerability. Cloud providers use memory deduplication to improve efficiency, sharing identical memory pages among multiple virtual machines running on the same host. But the researchers discovered that an attacker could use the page faults caused by writing to these shared pages as a side‑channel to detect the randomized base addresses of libraries in neighboring VMs—effectively breaking Address Space Layout Randomization (ASLR) for cloud tenants. The attack, dubbed “Silently Breaking ASLR in the Cloud,” demonstrated that even the most fundamental protections could be undermined by the cloud’s own optimizations.
The Black Hat Arsenal, a showcase of cutting-edge security tools and techniques, featured several innovative projects, including a presentation on the exploitation of USB devices. The Pwnie Awards, often referred to as the "security Oscars," recognized notable achievements in security research, with awards going to researchers who discovered critical vulnerabilities in popular software. blackhat.2015

The film's opening sequence is a masterclass in visual metaphor. Instead of a cartoonish digital grid, Mann’s camera plunges into the physical architecture of a computer. We travel through the circuit boards, fiber-optic cables, and pulsating server stacks, watching the glowing pulses of electricity that represent data. This sequence bridges the gap between the invisible code and the tangible physical destruction it causes, predating real-world anxieties about infrastructure hacking that dominate today's news cycles.
