Security analysts can move past traditional Indicators of Compromise from threat intel like domains, hashes, URLs, and IP addresses.

Following in the footsteps of an attacker and uncovering their digital footprints, this episode will uncover an attacker’s techniques used and how they went from zero to full domain admin compromise, which resulted in a nasty ransomware incident. It will also cover general lessons learned from Ransomware Incident Response.
