Polyverse changes the economics of hacking by making safe, economical changes to code patterns hackers need to exploit. For example, reordering functions in memory defeats many of the most devastating fileless and zero-day attacks. We implement these changes by tweaking or extending compilers, linkers, loaders, intermediate passes, and other parts of the execution environment.
Core to Polymorphic Linux are modifications to GCC, LLVM and other compiler tool chains. Compilers make many choices. For example, register assignment often has a choice of registers, and instruction schedulers often have a choice of instructions to schedule next. Typical compilers use fixed and thus hackable patterns, but ours break ties randomly at every compilation. By recompiling Linux for every customer, no two clients run the same executables, which foils hacks built on ROP gadgets.
We are expanding our toolset across platforms, compilers, architectures and implementations (e.g., plug-ins). As a Senior Compiler Engineer, you'll be responsible for implementation from concept/design to testing/performance to productization/support.
Here are a couple of examples of past projects:
You will also be working closely with the build farm and serving team. Polyverse runs the largest build farm in the world, constantly building unique copies of Alpine, CentOS, Fedora, Red Hat and Ubuntu.
