Threat hunting is proactively looking for attackers your alerts missed. Here's the hypothesis-driven loop and how a good hunt becomes a permanent detection.
Read guideDNS is almost always allowed out - so attackers smuggle data and C2 through it. Here's how DNS tunneling works and the metrics that catch it.
Read guideCommand-and-control implants 'phone home' on a schedule. Learn to spot beaconing by its rhythm - even when the traffic is encrypted and jittered.
Read guideExfiltration is the goal of most intrusions. Learn the channels attackers use to move data out and the signals that catch it before the breach is complete.
