Jay Harris - Putting Flutter in the Gutter: how to reverse engineer flutter applications

Talk recording coming soon

In the ever-evolving landscape of mobile application development, Flutter has emerged as a powerful framework, enabling developers to create cross-platform applications with a single codebase. However, with innovation comes the need for robust security measures. This talk aims to delve into the realm of reverse engineering and security assessment specific to Flutter mobile applications. Reverse engineering, the process of dissecting and understanding the inner workings of an application, is a double-edged sword. While developers leverage it for debugging and optimization, adversaries exploit it to identify vulnerabilities and potential security weaknesses. In this presentation, we will explore various reverse engineering techniques tailored to Flutter apps, shedding light on the underlying architecture and highlighting potential attack vectors.

Assembly and Disassembly, an OWASP guide to application security - 15 January 2024


In this session we discussed application security and the basics of assembly.


Stuart Crawford - AppSec in the Enterprise: in-flight testing and Shifting Left

Talk recording

In a world where web-based applications are ubiquitous, penetration testing is well-established as a way of verifying those applications are secure, but how do we stop finding ourselves falling into an endless cycle of 'deploy, test, fix'? The answer is by paying closer attention to security in the development lifecycle, and I'll provide an example of how we're doing this at one of, if not the largest Independent Software Vendors in the UK

About Stuart Crawford
Stuart is Appsec program manager at one of the largest SaaS companies in the UK

Tom Blue - Basic Assembly and Memory

Talk recording

This talk would be an overview of how basic assembly and memory works, the structure of programs compiled in C and how to follow the logic of disassembled programs. I’ll show how to use tools such as ghidra to decompile code and to make the reverse engineering process more efficient and cover things such as buffer overflows, patching code and return oriented programming.

About Tom Blue
Tom is a second year student studying computer science.

Breaking Yourselves, But In The Best Way Possible - 21 September 2023


In this session we'll be discussing various ways to improve your offensive security testing. Using these offensive security techniques, your teams will find new ways to break applications, and test your defenses.


Dr Katie Paxton-Fear: Go Hack Yourself: API hacking for beginners

Talk recording

Over the past few years, we've really seen API hacking take off as a field of its own, diverging from typical web app security, but yet parallel to it. Often we point to the amorphous blob that is web security and go: "here you go, now you can be a hacker too", with top 10 lists, write-ups, conference talks and whitepapers smiling as we do. This creates a major challenge for developers who want to test their APIs for security or just people who want to get into API hacking, how on earth do you wade through all the general web security to get to the meat of API hacking, what do you even need to know? This talk is going to break down API hacking from a developer point of view, teaching you everything you need to know about API hacking, from the bugs you can find and to the impact you can cause, to how you can easily test your own work or review your peers. So what are you waiting for join me and go hack yourself!

About Dr Katie Paxton-Fear
A lecturer in Cyber Security at Manchester Metropolitan University and a cyber security researcher, but she's far more well known for her hobby. In her free time, she's a hacker, specialising in API hacking teaching others through her YouTube videos. A former developer turned hacker, she used to make RESTful APIs and now she breaks them. She found her first API vulnerability in 2019 which affected Uber and since then she has been hacking APIs ever since, creating hours of content to help others follow in her footsteps. With her PhD in cyber security and machine learning, she loves to introduce a data-driven approach to hacking combining new tools with manual testing to ensure an impactful bug report every time.

Gerald Benischke - Application DoS vulnerabilities

Talk recording

This AppSec-focussed talk demonstrates how denial of service attacks can be carried out without throwing lots and lots of traffic at a system and effectively stop services. This uses a couple of vulnerabilities in the play framework as an example and describes the impact. This approach can be likened to using precision guided missiles rather than the carpet bombing of DDoS attacks. I will explore the role that convenience for developers in frameworks combined with unexpected payloads and how this can be exploited. I also draw on how the service mesh can amplify this attack such that multiple instances can be killed with a single request. Furthermore, we look at how Web Application Firewalls (WAFs) offer no protection against this type of attack. Lastly, I will look at what can be done to protect applications against this type of attack.

About Gerald Benischke
I tend to describe myself as both an Agile Fundamentalist and an AppSec Snooper. What does this mean? On the one hand my software development experience has led me to think that the principles of the agile manifesto form the basis of good practices. It boils down to lots of common sense, small steps, learning along the way, not writing code that nobody will want or need and taking processes and procedures with a pinch of salt.

Talk recording

This talk will explain what a SBOM (Software Bill of Material) is, how and when they should be produced / some of the challenges that need to be overcome, and demonstrate how they should form part of a DevSecOPs lifecycle. I will try and supplement the talk with some demonstrations using a number of open source applications.

Proactive Security - How do you prevent vulnerabilities? - 7 March 2023


In this session we'll be discussing Proactive Security. Meaning, how do you empower and enable engineering teams to own their own security to prevent the release of vulnerable code... What would secure coding practices look like, what is security by design, what security testing can teams do during the test & release process. More importantly, what can we put in place to really make the security teams work for their money.

The CTF itself will be a jeopardy style challenge aimed at a range of technical capabilities, with some low or non tech challenges. So, if you're a developer, software tester, system architect, infosec professional, or just have an interest in security sign up. We'll be running teams of 4, so you can either enter a full team or we can help you put one together on the day! Manchester Grey Hats will be running a series of short workshops on the same topics as the CTF on October 24th, so keep an eye on their Meetup page!
