Processes may own resources, but threads get work done. In this module you craft threads from scratch with NtCreateThreadEx, peek into their private stacks and TEBs, and gather live stats via NtQueryInformationThread. Pavel then unpacks the Native APIs for keeping threads in line: waits, APCs, and low-level synchronization, culminating in thread-pool discussion that showcases practical concurrency patterns. By the end you’ll be comfortable creating, inspecting, synchronizing, and fine-tuning threads-skills that power everything from stealth implants to high-throughput servers.
