    "description": "SocksTrace is a Linux-based proxy leak detector and traffic proxifier built on seccomp-notify. By intercepting network syscalls directly in the kernel, it provides runtime-agnostic visibility and enforcement that works even for statically linked binaries and modern browsers.\r\n\r\nThe talk showcases real WebRTC-related proxy leaks discovered using SocksTrace, explains shortcomings of traditional tools, and demonstrates transparent SOCKSification, DNS enforcement, and safe handling of applications that launch their own Tor instances. We conclude with practical use cases and future directions for syscall-level network containment.",
