Thinking Like an Adversary: Using ATT&CK to Build a Threat Hunt Scope
Effective threat hunting starts before you open the SIEM. This covers how to think through attacker decision-making, map realistic technique selections to your specific environment, build a coverage gap analysis against MITRE ATT&CK, and convert the gaps into a prioritised, testable hunt plan.

Kernel-Level EDR Tampering: How Attackers Remove Your Visibility at the Source
Beyond BYOVD, attackers have multiple methods to tamper with EDR at the kernel level: callback removal, minifilter bypass, ETW provider patching, and kernel object manipulation. Each requires different detection approaches. This covers all of them.

Supply Chain Attacks and Trusted Binary Abuse: When Your Own Software is the Threat
Supply chain attacks compromise software before it reaches you. Trusted binary abuse exploits legitimately signed executables to deliver malicious payloads. Both are among the hardest techniques to detect because the initial indicator is valid software doing what it is supposed to do.

Golden Tickets, Silver Tickets, and Diamond Tickets: Forged Kerberos and How to Detect Them
A Golden Ticket forged with the krbtgt hash grants unlimited access to every service in the domain for 10 years. Silver Tickets are service-specific but require no DC contact at all. Diamond Tickets are a newer variant designed to evade Golden Ticket detection. This covers detection for all three.

Memory-Only Malware: Hunting Threats That Never Touch Disk
Fileless malware executes entirely in memory, leaving no binary for file-based scanning to find. PowerShell cradles, .NET reflection loading, shellcode injection, and process hollowing are all fileless techniques. This is how to detect execution that never touches disk.
