Never Ending Security

It starts all here

Florida State University’s Offensive Computer Security Spring 2013 – CIS4930 & CIS5930

The primary incentive for an attacker to exploit a vulnerability, or series of vulnerabilities is to achieve a return on an investment (his/her time usually). This return need not be strictly monetary—an attacker may be interested in obtaining access to data, identities, or some other commodity that is valuable to them. The field of penetration testing involves authorized auditing and exploitation of systems to assess actual system security in order to protect against attackers. This requires thorough knowledge of vulnerabilities and how to exploit them. Thus, this course provides an introductory but comprehensive coverage of the fundamental methodologies, skills, legal issues, and tools used in white hat

[No video was recorded for this lecture due to technical difficulties]

This lecture finishes up the networking overview from last time.


Lecture 12: Web application Hacking 101

Its a bit shorter than other videos as the class time was taken up going over homework beforehand. This lecture addresses some of the big picture with the topics covered so far, and moves into web application security topics.


Week 7 (Web Application Hacking)

Week 8 (Web Application Hacking / Exploit dev)

Lecture 15: Web Application Hacking 104 & Exploit Development 104

This class was two lectures in one. In the web application 104 lecture we cover topics like WAF, and IDS and how to evade them – which leads into the exploit development 104 lecture. In the exploit dev 104 section we cover topics like networking shellcode, polymorphic shellcode / encoders, and the methodology for defeating IDS/WAF


Lecture 16: Midterm review & Exploit Development 105 (ROP)

This lecture’s first half is a review of topics for the midterm. The second half introduces Return Oriented Programming.


Week 9: (Special Topics)

Lecture 17: The Modern History of Cyber Warfare

This lecture covers just a small sample of the major events one might consider part of the history of cyber warfare. The lecture discusses some of the potential tactical and strategic differences between traditional warfare and cyber warfare – as well as the policy and perspective hurdles we face today. This lecture happened shortly after the ground-breaking APT1 report from Mandiant.


Lecture 18: Social Engineering

The first portion of this video is a continuation of the previous lecture on cyber warfare. Afterwards, this lecture offers a new spin on social engineering – by staring with fundamental psychological flaws in the human brain, and discussing how they can be exploited…


Week 10 (Metaspl0it):

Lecture 19: Metasploit

This lecture covers the metasploit framework, its interfaces, basic usage, and some of its utilities, along with a brief discussion of the social-engineering toolkit (SET)…



No video for this class…

The midterm was at this point, covering lectures 1-16.

Week 11 (Post Exploitation and Forensics):

Lecture 20: Meterpreter and Post Exploitation

This lecture starts by finishing the SET discussion from last time, covers Windows access-tokens, then delves into meterpreter and post exploitation…


Lecture 21: Volatility and Incident Response:

This lecture covers an overview of Incident Response and delves into Volatility and memory analysis..


Week 12 (Physical Security):

Midterm / Homework recap (no lecture)

No video for this class…

The lecture was sacrified for administrative things like reviewing the midterm, homeworks, and term project expectations.


Lecture 22: Physical Security Workshop: Lockpicking, USB mischief, and BacNET/SCADA system security
