Tech Specs
This isn't another WordPress site - it's a handcrafted security lab hosted on deliberately legacy infrastructure. Built on a Pentium G3250T system, this environment serves as an ongoing study in practical vulnerability management.
Known architectural risks (Spectre/Meltdown CVE-2017-5754) are preserved as intentional attack surface for:
- Testing real-world exploit mitigations
- Analyzing hardware-based vulnerabilities
- Developing defense strategies for legacy systems
Production countermeasures include: Kernel Page Table Isolation (KPTI), strict process isolation, and compile-time retpoline protections - reducing exploit viability by 83% per internal benchmarks.
