A working library of security explainers. Each topic starts with what the failure mode is in plain language, why it matters for your business, and what an attacker actually does. The technical detail follows for readers who want to go deeper.
Penetration Testing
The fundamentals. What a pentest is, how it differs from other security activities, the methodology stages, and what a useful report contains.
Active Directory Security
Active Directory controls who can log in to what across a Windows network, which makes it the prize in almost every enterprise breach. How AD actually gets attacked, from enumeration to full domain control.
Privilege Escalation
How an attacker turns a small foothold into full control of a machine: root on Linux, SYSTEM on Windows. The real paths and how to find them.
Lateral Movement and Pivoting
How one compromised machine becomes many: reusing credentials and remote-execution tools to spread across the network, and tunneling through a foothold to reach internal systems.
Containers and Kubernetes
How one weak pod becomes a cluster takeover: container escapes, the Docker runtime risks, and the Kubernetes attack surface.
Credential Access and Dumping
How attackers steal the passwords, hashes, and tickets that move them across a network, from memory, registry hives, disk, and the wire.
Persistence and Backdoors
How attackers keep access after the first compromise, surviving reboots and password resets via registry keys, scheduled tasks, services, web shells, and rogue accounts.
AI Security
Attacks against LLM-backed applications: prompt injection, RAG poisoning, jailbreaking, model extraction, agentic-system risks, training poisoning, and the OWASP LLM Top 10 (2025).

Application Security
How web applications get compromised, and the architectural decisions that prevent it. The most common flaw classes still drive most modern breaches.
Smart Contract Security
On-chain code is public, immutable, and holds real money, so a single bug can be drained in one transaction. How audits work and the web3 vulnerabilities they catch.
Cloud Security
How cloud environments actually get compromised in 2026: not by zero-days in the cloud provider, but by misconfigured IAM, instance metadata abuse, leaky storage, and pivot paths through Kubernetes.
API Security
Modern applications are mostly APIs with a thin user interface on top. The attack surface moved with them.
Mobile App Security
How iOS and Android apps get compromised, what the OWASP mobile standards ask for, and the techniques testers use to get past on-device protections.
