Hack the Box - Forest

HTB Forest machine walkthrough. Forest started with Windows enumeration using SMB and LDAP queries that lead to leveraging a lingering service account with PRE_AUTH disabled for user access. Once on the machine, we were able to abuse the existing Active Directory entitlements to create a malicious user entry with the rights to perform a DCSync using Mimikatz to acquire the Administrator's hash, finally using it to execute a pass-the-hash escalation to Administrator.

Hack the Box - Postman

HTB Postman machine walkthrough. Postman was a quick, simple machine from HTB. We start off with a redis exploit for initial foothold, then pivot to user by using JTR to crack a backup SSH key before finally using an authenticated Webmin exploit to escalate ourselves to root.

Hack the Box - Bankrobber

Starting with a client side XSS exploit to get admin app credentials, then chaining it with a localhost code execution bypass we get a user priviledged shell. A suspicious app running locally as System then presented a ... delicate ... buffer overflow opporunity to pivot into System priviledges.

Hack the Box - Zetta

HTB Zetta machine walkthrough. Starting with an FTP FXP IPv6 leak, to an rsync brute-force for user access to the machine. Once on, chained custom syslog messages with a postgres SQL injection to pivot user access. Finally, a dubious password policy leads to using discovered credentials and adapting them to the root password for system level access.

Quantum Computing - Hello World

An introductary look into Quantum Computing including the mechanics, concepts and mathematics involved. The focus will then shift to a practical implementation of these concepts using simulated environments and the qiskit python framework.

Hack the Box - AI

HTB AI machine walkthrough. Initial portions were more frustrating than complicated, reminiscent of daily struggles dealing with various home assistants. Once foothold was established priviledged escalation to root involved abusing a java debugging process running locally.
