Shellcode detection is critical in the identification of persistent threats. Attackers employ them in exploitation, post-exploitation toolkits and macro-based malware routinely to evade detection. Our research also shows that shellcode in the wild are evolving to defeat many of the static analysis techniques employed to detect them.
We will present a fast, platform agnostic approach (Windows/Linux) that been successful in detecting many real world shellcode compromises as part of the ASC Fileless attack feature (Process Investigator).
Our approach employs state machines, virtual stack/register representation and operand expression heuristics to identify suspicious machine code patterns in milliseconds.
We identify the basic heuristics that are commonly employed in shellcode. This allows us to be more robust against attackers that constantly evolve to thwart pure signature or byte stream sequence based approaches.
Each instruction is passed to a series of activation functions that look for platform specific patterns generally needed in Stage 1 shellcode. As we process the stream of instructions we scan for hashing loops, in-segment/out-segment calls/jumps, current instruction pointer determination, system calls, locating system data structures, anti-debugging and anti-hooking behaviors in the machine code. We then correlate these findings to give a maliciousness score.
We will deep dive into the concepts and demo obfuscated shellcodes.

A software bug is an error in a computer program that produces unexpected or incorrect results. Security bugs compromise authentication, authorization, data confidentiality, or integrity. Hackers find security bugs through reverse engineering code or fuzzing software to discover vulnerabilities. An exploit is a piece of code that activates a bug to run malicious code. Shellcode is typically used as the payload in an exploit to gain control of a compromised system. Cyber attacks can target individuals, networks, or remote systems. Advanced persistent threats (APTs) are sophisticated, well-funded hacking groups that persistently target specific entities over long periods using social engineering and zero-day exploits. APT attacks involve penetrating targets, spreading to other systems, aggregating data, and covert

DLLs are like EXEs but are not directly executable. They contain functions that can be called by EXEs or other DLLs and allow code to be shared among applications to reduce memory usage and disk space. DLLs use the same PE file format as EXEs and save resources by loading shared code only once into memory rather than in each application. However, DLL hijacking is possible if a malicious DLL with the same name is placed where an application looks first.

Project Management Course
Over the past few decades, organisations have discovered something incredible: the principles that lead to great success on large projects can be applied to projects of any size to achieve extraordinary success. As a result, many employees are expected to be familiar with project management techniques and how they apply them to projects.

Using ScyllaDB for Real-Time Write-Heavy WorkloadsScyllaDB
Keeping latencies low for highly concurrent, intensive data ingestion
ScyllaDB’s “sweet spot” is workloads over 50K operations per second that require predictably low (e.g., single-digit millisecond) latency. And its unique architecture makes it particularly valuable for the real-time write-heavy workloads such as those commonly found in IoT, logging systems, real-time analytics, and order processing.
Join ScyllaDB technical director Felipe Cardeneti Mendes and principal field engineer, Lubos Kosco to learn about:
- Common challenges that arise with real-time write-heavy workloads
- The tradeoffs teams face and tips for negotiating them
- ScyllaDB architectural elements that support real-time write-heavy workloads
- How your peers are using ScyllaDB with similar workloads
Selling software today doesn’t look anything like it did a few years ago. Especially software that runs inside a customer environment. Dreamfactory has used Anchore and Ask Sage to achieve compliance in a record time. Reducing attack surface to keep vulnerability counts low, and configuring automation to meet those compliance requirements. After achieving compliance, they are keeping up to date with Anchore Enterprise in their CI/CD pipelines.
The CEO of Ask Sage, Nic Chaillan, the CEO of Dreamfactory Terence Bennet, and Anchore’s VP of Security Josh Bressers are going to discuss these hard problems.
In this webinar we will cover:
- The standards Dreamfactory decided to use for their compliance efforts
- How Dreamfactory used Ask Sage to collect and write up their evidence
- How Dreamfactory used Anchore Enterprise to help achieve their compliance needs
- How Dreamfactory is using automation to stay in compliance continuously
- How reducing attack surface can lower vulnerability findings
- How you can apply these principles in your own environment
When you do security right, they won’t know you’ve done anything at all!
The Challenge of Interpretability in Generative AI Models.pdfSara Kroft
Navigating the intricacies of generative AI models reveals a pressing challenge: interpretability. Our blog delves into the complexities of understanding how these advanced models make decisions, shedding light on the mechanisms behind their outputs. Explore the latest research, practical implications, and ethical considerations, as we unravel the opaque processes that drive generative AI. Join us in this insightful journey to demystify the black box of artificial intelligence.
Dive into the complexities of generative AI with our blog on interpretability. Find out why making AI models understandable is key to trust and ethical use and discover current efforts to tackle this big challenge.

3. Agenda
• What we will cover - Fuzzing Buffer Overflow(EIP Overwrite)
ShellCode Execution Ownage
• What we will do - EIP overwrite, which will allow us to gain control of
program execution and redirect it to our shellcode
• How we will do – Exploiting stack based buffer overflow in the
Windows application MiniShare 1.4.1.
4. Fuzzing
• Fuzzing is a process of sending deliberately malformed data to a
program in order to generate failures, or errors in the application.
• When performed by those in the software exploitation community,
fuzzing usually focuses on discovery of bugs that can be exploited to
allow an attacker to run their own code, and along with binary and
source code analysis.
• Fuzzing is one of the primary ways in which exploitable software bugs
are discovered.
5. BufferOverflow
• A buffer overflow is a condition when a program attempts to put
more data in a buffer than it can hold or when a program attempts to
put data in a memory area past a buffer.
• The general idea is there is an application that accepts input from a
user without any bounds checking. This allows us to overwrite the
memory space “buffer” and hopefully overwrite the EIP register
which will allows us to redirect program execution to our shellcode.
6. Shellcode
• A shellcode is a small piece of code used as the payload in
the exploitation of a software vulnerability.
• It is called "shellcode" because it typically starts a command
shell from which the attacker can control the compromised
machine.
• Shellcode can either be local or remote. In our case, it is local and
not remote.
7. System Requirement
1. VM platform (Virtualbox, VMware, etc.)
2. Have a Windows 32-bit XP VM and a Kali Linux VM
3. OllyDbg Debugger.
4. Minishare 1.4.1 -

8. Assembly Basics
• Assembly language is considered a low level language that is a human
readable version of a computer’s architecture instruction set.
• Since we cannot learn assembly within a day just remember –
1) Instruction Pointer: EIP – Register that contains the memory
address of the next instruction to be executed by the program. EIP tells
the CPU what to do next.
2) Stack Pointer: ESP – Register pointing to the top of the stack
at any time
