Top Active Directory Attacks: Understand, then Prevent and Detect

Talkat RSAC 2021 · 2021-05-17..05-20· [security]
slides:none on file

Covers concrete AD failures and fixes: email phishing causes 90%+ breaches, internal access plus privileges lets attackers win fast (example: 65 minutes to domain-wide ransomware), common vectors include password spraying and credential stuffing, exposed file shares and MFPs, DNS fallback/LLMNR abuse, and Kerberos attacks (krbtgt golden tickets, silver tickets, Kerberoastable accounts). Shows tools and steps: enumerate subnets with PowerShell, scan with Eyewitness, crackable-service finds via Rubeus, search secrets with Snaffler, and defenses like Azure AD Password Protection, SMB signing and managed service accounts.
