Dagmar Heidecker works as a Principal Consultant for Microsoft's Compromise Recovery team. An essential part of this role is to quickly figure out whether PKI has been actively abused during an attack or has vulnerabilities or misconfigurations which might allow attackers to strike back. Working in this area for many years, she has analyzed many attacks against PKI, Active Directory, Azure and other types of infrastructures.
Dagmar's first point of connection with PKI was during writing her master thesis in the 1990s. Since then, PKI always has been part of her work.
