No PoCs? No problem. How to hunt for F5 exploitation even when details are sparse
Endpoint detection and response (EDR) tools, and the analysts using them, have become incredibly effective. They have become so good, in fact, that we're now seeing a clear shift in adversary behavior: attackers are being pushed off the endpoint and onto places where EDR cannot run.
