BYGH00ST | Solutions Architect & Cyber Security Specialist

Specializing in Hardware-Assisted Virtualization (Intel VT-x / KVM), eBPF Ring 0 Telemetry & Low-Level Forensics

Intel VT-x / AMD-V (VMX Root Mode): Bare-metal hypervisor execution, Extended Page Table (EPT) memory page integrity verification, and nested page table escape analysis.
KVM API & Micro-VM Sandboxing: Direct Linux KVM interfaces for independent VM/vCPU lifecycle management, hardware IOMMU isolation, and <5ms warm-VM ephemeral quarantine.
Low-Level Introspection: OS scheduler DKOM tracking, LSTAR MSR proxying for direct syscall interception, and RDTSC clock synchronization.

Linux Kernel Internals & LSM: Synchronous process execution interception via Linux Security Modules (LSM) and tamper-resistant eBPF security hooks (TC, XDP, LSM).
Line-Rate Packet Mitigation: Sub-microsecond L2/L3/L4 packet filtering at the NIC driver layer (eBPF/XDP) with zero-copy BPF ring buffers.
Hardware Execution Telemetry: CPU PMU 32-slot LBR (Last Branch Record) for hardware-level ROP/JOP exploitation detection.

Binary Parser & Emulation: Structural parsing of PE, ELF, and Mach-O binaries with CPU-level code emulation using Unicorn Engine & Capstone disassembler.
Telemetry Analysis: Real-time Windows ETW / ETWTI kernel event mapping directly into the MITRE ATT&CK matrix.
Signature & Memory Scanning: Dynamic and static memory inspection engines powered by YARA-X.

Zero-Allocation Raw Sockets: Packet crafting engines with manual TCP checksum/sequence verification and strict state-machine auditing.
TLS & Protocol Camouflage: Real-time JA3/JA3S/JA4 TLS fingerprint synthesis, RFC 8701 GREASE injection, and HTTP/2 HPACK compression auditing.
Identity Protocol Auditing: Enterprise authentication security boundary analysis across Active Directory, Kerberos, NTLM, and DNSSEC.

Android NDK (C++20): Hardware Abstraction Layer (HAL) security controls with zero-GC native memory safety.
Runtime Application Self-Protection (RASP): Anti-debugging, memory tampering countermeasures, dynamic hook detection, and hardware-backed DRM integration.
