Incident teardowns, detection engineering, reverse engineering and network forensics. Filtered to credential-access.
A burst of Kerberos service ticket requests from one workstation, every one of them legitimate as far as the domain controller is concerned. Find what makes the cluster abnormal, separate it from a legacy application, and say what the log cannot tell you.
An LSASS dump taken with a DLL that ships in System32, called by ordinal so the obvious rule misses it. Work out which process touched LSASS, which access mask matters, and whose credentials you now have to assume are gone.
A password spray that stayed under the lockout threshold and never produced a failed-logon event on the server it was aimed at. Find where the failures were recorded, identify the account that fell, and explain why the dashboard showed nothing.
A constructed intrusion written as a DFIR report. You get the same artifacts an analyst gets on day one, in the order they arrive, and you build the timeline yourself. The company is fictional; the techniques, event IDs and analytic reasoning are not.
