The last few months have been busy in the best ways. Work has been nonstop, family life has been full, and I have not had as much time to write as I normally do.

I did carve out some time to dig into Microsoft’s GigaWiper research and the new Sentinel Repositories preview. That turned into a hands-on detection engineering lab with five Defender XDR detections, GitHub Actions validation, safe endpoint testing, and three custom alerts correlated into one incident.

The most interesting part was that not everything worked perfectly. The native deployment path failed in my environment, so I documented what worked, what did not, and what the evidence actually proved.

It felt good to get back into the weeds and finally publish something new.
