OSI/TCP-IP models, packet structures, binary subnetting, ARP spoofing mechanics, DNS resolution hierarchy, and live Wireshark packet inspection.
Filesystem hierarchy, process management (`/proc`), SUID/SGID permissions, systemd services, automated Bash tooling, and regex stream filtering.
NTFS permissions, Registry forensics, SAM/LSASS process security, Windows Event Logs, and offensive/defensive PowerShell scripting.
OWASP Top 10 deep dive: SQLi, Blind XSS, SSRF, IDORs, broken access control, JWT tampering, and automated API fuzzing with Burp Suite.
Reconnaissance, service scanning, Kerberoasting, AS-REP Roasting, Pass-the-Hash, BloodHound attack path auditing, and domain dominance.
Log aggregation, correlation rules, Sigma detection logic, Splunk SPL queries, Suricata IDS/IPS alerting, and proactive threat hunting.
Disk imaging, RAM memory dumps with Volatility, MFT/Prefetch/Shimcache artifact recovery, lateral movement reconstruction, and containment.
AWS/Azure IAM privilege escalation, S3 bucket misconfigurations, Docker container breakouts, Kubernetes RBAC hardening, and CI/CD secret scanning.
Static disassembly with Ghidra, dynamic stepping with x64dbg, PE header structure analysis, anti-debugging bypasses, and sandbox detonation.
LLM prompt injection, jailbreaking, agentic data exfiltration, MITRE ATT&CK framework mapping, and Cyber Threat Intelligence (CTI) feeds.
Reading notes without breaking code is useless. These are the verified, hands-on platforms where you build muscle memory.
Bandit and Natas war-games. The non-negotiable rite of passage for mastering the Linux command line, pipes, and raw SSH mechanics.

Reading theory creates illusions of competence. Reproduce every vulnerability in an isolated virtual machine.
You cannot properly defend what you cannot exploit, and you cannot stealthily exploit what you cannot detect.
Professional security engineers write clean, reproducible technical reports with verifiable proof of concepts.
