Adversaries may create self-signed code signing certificates that can be used during targeting.
Detect it with
Consider analyzing self-signed code signing certificates for features that may be associated with the adversary and/or their developers, such as the thumbprint, algorithm used, validity period, and common name.
Why it matters on shift

What to look for next
After resource development, the next tactic is usually Initial Access. Search your telemetry for the transition before closing the ticket.
