7MS #551: Interview with Matt Warner of Blumira

Today we welcome our pal Matthew Warner (CTO and co-founder of Blumira) back to the show for a third time (his first appearance was #507 and second was #529). I complained to Matt about how so many SIEM/SOC solutions don't catch early warning signs of evil things lurking in customer networks. Specifically, I whined about 7 specific, oft-missed attacks like port scanning, Kerberoasting, ASREPRoasting, password spraying and more. (Shameless self-promotion opportunity: I will be discussing these attacks on an upcoming livestream on December 29). Matt dives into each of these attacks and shares some fantastic insights into what they look like from a defensive perspective, and also offers practical strategies and tools for detecting them! Note: during the discussion, Matt points out a lot of important Active Directory groups to keep an eye on from a membership point of view. Those groups include: ASAAdmins Account Operators Administrators Administrators Backup Operators Cert Publishers Certificate Service DCOM DHCP Administrators Debugger Users DnsAdmins Domain Admins Enterprise Admins Enterprise Admins Event Log Readers ExchangeAdmins Group Policy Creator Owners Hyper-V Administrators IIS_IUSRS IT Compliance and Security Admins Incoming Forest Trust Builders MacAdmins Network Configuration Operators Schema Admins Server Operators ServerAdmins SourceFireAdmins WinRMRemoteWMIUsers WorkstationAdmins vCenterAdmins
