Stratagems #18: Leo Tracked an AI Signal to Derek. Both Were Looking for the Same Enemy.
Short summary
This is a serialized techno-thriller chapter where Leo, probing an old ACL-linked IP range, discovers an unexpected node sending data to an ACL collector endpoint. Derek, a test engineer monitoring a healthcare sandbox, simultaneously detects Leo's probe and recognizes it as a non-ACL actor using architect-level techniques. The two adversaries circle each other through network probes, silence traps, and ICMP signals, each trying to confirm the other's identity without revealing their own.
- •Leo detects an external node leaking ACL metadata signatures during an HTTPS probe to a collector endpoint
- •Derek spots the same probe on his sandbox and sets a silence trap to observe the intruder's behavior
- •Both characters realize the other is not ACL and is investigating the same hidden adversary
