Hack the Box - Tabby

HTB Tabby machine walkthrough. Tabby starts off with careful recon enumeration leveraging local file inclusion to harvest credentials then using those credentials to establish a foothold through Apache manager script usage. User escalation then came through a backup zip file encrypted with the user's system password, gathered by using zip2john. Lastly root privesc was achieved by leveraging LXD system container manager as the regular user was part of the lxd control group. Overall this was a fun box to get back into the swing of things after a couple month hiatus and I learned a few tips and tricks.

Org-in-a-Box - Kerberos & NFS

Second post covering my personal project of an organization in a box. Based on the initial architecture this article goes over partially setting up the first two authentication servers in the project leveraging MIT Kerberos and NFSv4. These hosts will serve as the core base for the rest of the Org-in-a-Box project and a subsequent post will cover the LDAP and DBIS configuration on these hosts.
