### AI overview

This article examines attacks against smart-card-enforced Active Directory networks. It explains that a physical smart card is not necessarily required for smart-card logon when the corresponding private key is available, describes certificate requirements and policy-related certificate abuse, and introduces PKINIT as public-key support for Kerberos pre-authentication.

### Source excerpt

Introduction Recently I was involved in an engagement where I was attacking smart card based Active Directory networks. The fact is though, you don't need a physical smart card at all to authenticate to Active Directory that enforces smart card logon. The attributes of the certificate determine if it can be used for smart card [...] The post Attacking Smart Card Based Active Directory Networks appeared first on Ethical Chaos.
