Jagadeesh Parameswaran, Microsoft Rahul Sachan, Microsoft Windows Defender Advanced Threat Protection (WDATP) gives defenders unparalleled visibility into the enterprise. And Azure Advanced Threat Protection (AATP) gives the power to monitor attacks on the Domain Controllers and user identities. Come spend an hour with us as we pull back the covers and go through detailed examples of real attacks that we saw as we defended the Microsoft corporate environment using WDATP & AATP.

- 21. Horizontal Bruteforce: • a small set of passwords across many users Vertical Bruteforce: • a large set of passwords on just a few users
- 22. Not secure

- 24. COMPLEX
- 26. A real attack by an adversary A service / application that leverages LDAP Simple Binds rather LDAPS
- 39. Changed passwords of the compromised users Checked WDATP events in the victim machines to identify any suspicious process executions later the attack Asked them to use Strong Passwords to prevent Bruteforce attacks Checked any suspicious login for the user accounts using MCAS to identify any possible compromise / access of Exchange Online / SharePoint Online Data
- 44. Attacker was contacted to identify the necessary reasons for the attack This was done for experimental purposes by the attacker – as a Script kiddie Attacker was educated NOT to use any malicious activities using Tools or Scripts from the Microsoft CORP domain joined machines
- 48. LDAP Simple Bind Bruteforce attacks are simple, but are difficult to track Using AATP & WDATP, BF attack can be quickly detected Complex, Strong passwords help to prevent Bruteforce attacks

- 67. In less than two hours of successfully achieving access to the permanent domain admin account, Attacker used its hash to replicate the directory to their machine: Desktop-xxxx …. a non domain joined box…… a rogue Domain Controller …
- 71. Compromised account + Non DJ machine + Mimikatz can bring troubles to the AD AATP provides visibility to the attack targeting AD environment Rich time lines of WDATP helps to pinpoint anomalies of Domain joined machines
