This talk gives a short introduction into buffer overflows, how to exploit them and which counter measures are used in openSUSE Linux to make exploitation harder.
We'll cover stack canaries, fortify source, address space layout randomization and NX. We'll see how they work and how they can be circumvented in a live demo of a working exploit that manages to circumvent these security measures.
A quick tutorial on what debuggers are and how to use them. We present a debugging example using GDB. At the end of this tutorial, you will be able to work your way through a crash and analyze the cause of the error responsible for the crash.
Thoughts On Learning A New Programming LanguagePatricia Aas
How should we teach a new language to folks that already know how to program?
How do we use what we already know to leapfrog the learning process?
Based on my personal experience and snippets of natural language theory, we will try to explore the cheats and pitfalls when learning a new programming language, but also dig into how we can make it easier.
An introduction to exploit development.
I gave this talk at Hack the North 2014, and most of this information is pulled out of classics like Smashing the Stack for Fun and Profit, so there shouldn't be anything novel in here.
This presentation is designed to provide a basic overview of the following: System Organization, Memory Organization, Stack Organization (For Function Calls), A Vulnerable C Program, Exploiting Buffer Overflow

In this research, it concludes that while the readiness of teachers in Caloocan City to implement the MATATAG Curriculum is generally positive, targeted efforts in professional development, resource distribution, support networks, and comprehensive preparation can address the existing gaps and ensure successful curriculum implementation.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Thinking of getting a dog? Be aware that breeds like Pit Bulls, Rottweilers, and German Shepherds can be loyal and dangerous. Proper training and socialization are crucial to preventing aggressive behaviors. Ensure safety by understanding their needs and always supervising interactions. Stay safe, and enjoy your furry friends!

How to Build a Module in Odoo 17 Using the Scaffold MethodCeline George
Odoo provides an option for creating a module by using a single line command. By using this command the user can make a whole structure of a module. It is very easy for a beginner to make a module. There is no need to make each file manually. This slide will show how to create a module using the scaffold method.
4. OUTLINE
➤ main() is not the really main
➤ OllyDBG:Baby First (Exam)
➤ Return-oriented Programming
➤ Overflow: Revo Wolf(Exam)
➤ Fuzzing
➤ Make a fuzzer in C++
➤ How to fuzzing with Z3
16. REALLY MAIN
➤ Label “_start” is really main.
➤ CRTStartUp is loaded in label “_start”.
(To init RTC/new/delete/arg…etc)
➤ Find programmer’s main (normal c plus compile)
➤ Find the address calling GetCommandLine
➤ Find the address calling exit() or cexit()
➤ Programmer’s main function is between them.
51. BUFFER OVERFLOW
➤ We just can see , cannot modify the application.
➤ For Exploit?
➤ Overflow local variables. (EBP+N are good friend to us)
➤ Do something for get control EIP/RIP.
81. “ Fuzz testing or fuzzing is a software testing technique,
often automated or semi-automated, that involves
providing invalid, unexpected, or random data to the
inputs of a computer program. The program is then
monitored for exceptions such as crashes, or failing
built-in code assertions or for finding potential memory
leaks. Fuzzing is commonly used to test for security
problems in software or computer systems. It is a form
of random testing which has been used for testing
hardware or software.
From Wikipedia
WHAT IS
FUZZING?
82. When we need to
fuzz?A. Prove that something is always true
B. Fuzzing for something unexpected
C.Fuckinnnnnnnnnnnnng Crypto
D.A lot of choice, find one is correct
108. Z3 BEGIN
➤Get and Install Python2.7
✴ Z3.py script environment
✴ www.python.org
➤You can use python basically
➤Get Z3.py for Windows
✴ Prove tool
✴ github.com/Z3Prover/z3/wiki/Using-Z3Py-on-Windows
111. FUZZING(Z3)
BitVec(“Name” , BitCount)
For example:
1.char a => a = BitVec(“a”, 8)
2.short b => b = BitVec(“b”, 16)
3.int c => c = BitVec(“C”, 32) => Int(“c”)
4.bool e => e = BitVec(‘e’, 8)
112. FUZZING(Z3)
Solve(All rules ), Z3 will auto fuzz all variables,
and find a result(JUST ONE RESULT!).
Then, print all results of variables.
113. FUZZING(Z3)
If you have a looooot of rules,
you can use Solver().
Solver.add() can remember
all rules you requested.
114. FUZZING(Z3)
If you want to check current
whether rules can come true,
you just use: Solver.check()
117. FUZZING(Z3)
Finally, if you get “sat”,
you can use: Solver.model()
It will save a result in it.
Use model[Variable Name],
and get the answer by String
