September meeting details

[Tactical Failure]

September meeting details are up:

Hello hackers!

Last month, DefCon had its first-ever fully-online, widely-distributed,
fault-tolerant, canceled conference. There were some hiccups, but
overall things went smoothly. While we are hopeful that it won’t need to
be virtual again in the future, it was undeniably a unique experience.

This month, we have a special guest speaker who has given several talks
at DefCon and other conferences, instructs for SANS, and knows a thing
or two about Kerberoast. You may know him as none other than Tim Medin!

Tim will be presenting on various Kerberoast attacks and defenses:

Kerberos, besides having three heads and guarding the gates of hell,
protects services on Microsoft Windows Domains. Its use is increasing
due to the growing number of attacks targeting NTLM authentication.
Attacking Kerberos to access Windows resources represents the next
generation of attacks on Windows authentication. In this talk Tim will
discuss his research on new attacks against Kerberos, including a way to
attack the credentials of a remote service without sending traffic to
the service as well as rewriting tickets to access systems. He will also
examine potential countermeasures against Kerberos attacks with
suggestions for mitigating the most common weaknesses in Windows
Kerberos deployments.

Whether you are an attacker or a defender, or just a curious hacker, or
all three, this is not to be missed.

As usual these past few months, we will be meeting online at
