An expert guide for building scalable, cloud-native enterprise applications using the latest Java 21+ features, including Virtual Threads and Pattern Matching. Deep mastery of the Spring Boot 3.x ecosystem, Spring Cloud, and microservices architecture. Covers full development lifecycle, from JVM performance tuning (GraalVM, ZGC) to robust testing (Testcontainers) and secure DevOps practices (Kubernetes, CI/CD).

A deep dive toolset for forensic investigation of advanced persistent threats (APT) at the firmware level. It analyzes UEFI variable modifications, SPI flash implants, Secure Boot bypass techniques, and unauthorized components within the EFI System Partition (ESP). Utilizes tools like chipsec, flashrom, and YARA for comprehensive integrity verification.

CHIPSEC is an open-source framework designed to assess the low-level security configuration of x86 platform firmware and hardware. It verifies critical security controls such as SPI flash write protection, BIOS locks, SMM/SMRR configuration, and Secure Boot variable integrity. Users can run automated tests, dump SPI flash memories for forensics, and detect potential firmware implants that persist below the operating system layer.

A comprehensive security auditing tool designed to detect UEFI Secure Boot bypasses and advanced bootkits (like BlackLotus and Bootkitty). It verifies the Secure Boot state, checks the freshness of the dbx revocation list, and hashes EFI boot binaries against known-bad sets. Use this skill for auditing enterprise fleets after major bootkit advisories or for hunting pre-OS persistence on compromised endpoints.

This skill provides a comprehensive workflow for verifying the integrity of a system's boot chain using TPM 2.0. It covers local validation by reading Platform Configuration Registers (PCRs) and replaying the event log, and remote attestation by generating and checking signed quotes. Use cases include enforcing Zero Trust device posture, detecting firmware tampering, or establishing secure secret baselines.

This guide covers essential security best practices for Spring Boot applications. Learn how to implement robust authentication (JWT, OAuth2), authorization using method security, secure input validation, prevent SQL injection, manage secrets, and configure vital security headers (CORS, CSRF). Essential for building production-ready, secure Java backend services.

This guide outlines the methodology for conducting hardware security research on embedded systems. It covers physical interface analysis (UART, JTAG, SWD), debug pad triage, secure boot evaluation, and offline firmware extraction. It emphasizes systematic, non-destructive testing protocols and responsible handling of physical devices.
