A Hacker's perspective on AEM applications securityMikhail Egorov
Adobe Experience Manager (AEM), is a comprehensive content management solution for building websites, managing marketing content and assets. I started to look into AEM security back in 2015. Since then I discovered and reported several server-side vulnerabilities and developed toolset for AEM hacking to automate security testing of AEM web-applications.
In 2019 I reported one code injection and three XML external entity (XXE) vulnerabilities to Adobe PSIRT. They are known as CVE-2019-8086, CVE-2019-8087, CVE-2019-8088. These vulnerabilities allow anonymous attackers to compromise AEM web-application.
In the talk, I will disclose details of discovered vulnerabilities and exploitation techniques.
XSS is much more than just <script>alert(1)</script>. Thousands of unique vectors can be built and more complex payloads to evade filters and WAFs. In these slides, cool techniques to bypass them are described, from HTML to javascript. See also http://brutelogic.com.br/blog

The Secret Life of a Bug Bounty Hunter – Frans Rosén @ Security Fest 2016Frans Rosén
Frans Rosén has reported hundreds of security issues using his big white hat since 2012. He have recieved the biggest bounty ever paid on HackerOne, and is one of the highest ranked bug bounty researchers of all time. He's been bug bounty hunting with an iPhone in Thailand, in a penthouse suite in Las Vegas and without even being present using automation. He'll share his stories about how to act when a company's CISO is screaming "SH******T F*CK" in a phone call 02:30 a Friday night, what to do when companies are sending him money without any reason and why Doctors without Borders are trying to hunt him down.
Same Origin Method Execution (BlackHat EU2014)Ben Hayak
Exploiting A Callback For Same Origin Policy Bypass.
SOME - "Same Origin Method Execution" is a new technique that abuses callback endpoints in order to perform a limitless number of unintended actions on a website on behalf of users, by assembling a malicious set of timed frames and/or windows. Despite the similarity to click-jacking, this attack is not UI related nor it is confined in terms of user interaction, browser brand, HTTP X-FRAME-OPTIONS/Other response headers or a particular webpage, in fact, when a webpage found vulnerable to "SOME", the entire domain becomes vulnerable. During this talk, I intend to demonstrate how JSONP opens a backdoor, even in the most protected domains, to a very powerful attack that can cause severe damage without any user-interaction.
How to steal and modify data using Business Logic flaws - Insecure Direct Obj...Frans Rosén
Regardless on how sophisticated your framework is, how many layers of firewalls and mitigation techniques that are put in place, there's a common weakness that often gets overlooked: the insecure direct object reference. The flaw exist everywhere: WordPress with username enumeration issues. Twitter where remote attackers could delete credit cards for the ad service and to OculusVR with a horizontal privilege escalation vulnerability which got disclosed recently.
OWASP AppSecEU 2018 – Attacking "Modern" Web TechnologiesFrans Rosén
In this talk, top ranked white-hat hacker Frans Rosén (@fransrosen) will focus on methodologies and results of attacking modern web technologies. He will do a deep-dive in postMessage, how vulnerable configurations in both AWS and Google Cloud allow attackers to take full control of your assets.
Listen to 60 minutes of new hacks, bug bounty stories and learnings that will make you realize that the protocols and policies you believed to be secure are most likely not.
This talk shares the various techniques I found whilst building the XSS cheat sheet. It contains auto executing vectors, AngularJS CSP bypasses and dangling markup attacks.
DNS hijacking using cloud providers – No verification neededFrans Rosén
This is my talk from OWASP Appsec EU and also Security Fest 2017.
A few years ago, Frans and his team posted an article on Detectify Labs regarding domain hijacking using services like AWS, Heroku and GitHub. These issues still remains and are still affecting a lot of companies. Jonathan Claudius from Mozilla even calls “Subdomain takeover” “the new XSS”. Since then, many tools have popped up to spot these sorts of vulnerabilities. Frans will go through both the currently disclosed and the non-disclosed ways to take control over domains and will share the specific techniques involved.
WAF Bypass Techniques - Using HTTP Standard and Web Servers’ BehaviourSoroush Dalili
Although web application firewall (WAF) solutions are very useful to prevent common or automated attacks, most of them are based on blacklist approaches and are still far from perfect. This talk illustrates a number of creative techniques to smuggle and reshape HTTP requests using the strange behaviour of web servers and features such as request encoding or HTTP pipelining. These methods can come in handy when testing a website behind a WAF and can help penetration testers and bug bounty hunters to avoid drama and pain! Knowing these techniques is also beneficial for the defence team in order to design appropriate mitigation techniques. Additionally, it shows why developers should not solely rely on WAFs as the defence mechanism.
Finally, an open source Burp Suite extension will be introduced that can be used to assess or bypass a WAF solution using some of the techniques discussed in this talk. The plan is to keep improving this extension with the help of the http.ninja project.
Ekoparty 2017 - The Bug Hunter's Methodologybugcrowd
Goals of this Presentation:
- Outline and provide an actionable methodology for effectively and efficiently testing for, and finding security vulnerabilities in web applications
- Cover common vulnerability classes/types/categories from a high level
- Provide useful tools and processes that you can take right out into the world to immediately improve your own bug hunting abilities
Nowadays REST APIs are behind each mobile and nearly all of web applications. As such they bring a wide range of possibilities in cases of communication and integration with given system. But with great power comes great responsibility. This talk aims to provide general guidance related do API security assessment and covers common API vulnerabilities. We will look at an API interface from the perspective of potential attacker.
I will show:
how to find hidden API interfaces
ways to detect available methods and parameters
fuzzing and pentesting techniques for API calls
typical problems
I will share several interesting cases from public bug bounty reports and personal experience, for example:
* how I got various credentials with one API call
* how to cause DoS by running Garbage Collector from API
https://2018.zeronights.ru/en/reports/reverse-proxies-inconsistency/
Modern websites are growing more complex with different reverse proxies and balancers covering them. They are used for various purposes: request routing, caching, putting additional headers, restricting access. In other words, reverse proxies must both parse incoming requests and modify them in a particular way. However, path parsing may turn out to be quite a challenge due to mismatches in the parsing of different web servers. Moreover, request converting may imply a wide range of different consequences from a cybersecurity point of view. I have analyzed different reverse proxies with different configurations, the ways they parse requests, apply rules, and perform caching. In this talk, I will both speak about general processes and the intricacies of proxy operation and demonstrate the examples of bypassing restrictions, expanding access to a web application, and new attacks through the web cache deception and cache poisoning.
Demos: http://www.youtube.com/playlist?list=PL3SqEmKhsxzzUIG1oIOUw3UeK0euTSTNH
Chess is a complex game: The number of permutations is just too great to compute the best possible move during a game. This is similar to pen testing in that we also have too many vulnerabilities to find and choose from not only on a 1 by 1 basis but also how we would chain them together like a real attacker.
Chess players must analyse efficiently to beat time constraints like pentesters but unlike pentesters they have been doing this for a long time.
The purpose of this talk is to expose the techniques chess players have been using for centuries and to illustrate how we can learn from these and apply them to pen testing. The talk will behighly practical and will show how these techniques have been incorporated into OWTF, not only with screenshots but also demos.
Have you ever had to spend valuable time in the middle of a test to prepare something you could have prepared in advance? Did you ever analyse a vulnerability/attack-path in depth only to find a significantly easier to exploit vulnerability hours/days after? Pen testing is very similar to playing chess: It is easy to get carried on and waste valuable analysis time on a line of attack that is just not the best option. Maybe mistakes like this will be a bit less likely after attending this talk.
In just a few years, Open Policy Agent (OPA) has emerged as one of the hotter technologies for policy management and fine grained access control in the cloud native ecosystem. Now it’s coming for your APIs!
In this session we will explore the underlying concepts and some of the components involved in OPA before we get hands on in live coding test driven authorization policies to protect API endpoints.

Grails is revolutionizing web development in many corporate Java environments. However, leveraging managed content isn’t straight forward with the myriad of incompatible ECM systems prevalent in businesses. The Content Management Interoperability Services (CMIS) standard allows for products or applications to be built independently of the underlying content repository. CMIS and Grails is a powerful combination for handling document management activities and displaying web content assets within custom web applications. This session will explore: How to integrate a CMIS repository with Grails applications, Apache Chemistry OpenCMIS vs. roll your own, Authentication models, Practical considerations, Alfresco extensions to CMIS and OpenCMIS. The concepts will be presented before diving into a hands-on session with Grails.

Zsombor Kovács - Cheaters for Everything from Minesweeper to Mobile Banking ...hacktivity
In my opinion, cheating acceptable - it merely means expanding the frame of an application to the point, which is beyond what the creators of the application have ever imagined. In this talk, we explore how the popular instumentalisation framework Frida can be used to hack applications from games to mobile banking applications.
Vincent Ruijter - ~Securing~ Attacking Kuberneteshacktivity
This talks' focus lays on a popular containerization tool called Kubernetes. Common implementations of Kubernetes are not secure by default and a lot of information about hardening is not known to the public. Since version 1.7 the security level has increased and common security misconfigurations have been mitigated. During this talk it will be demonstrated what happens if these mitigations are not applied and how to abuse them. The talk will be about both securing and attacking the platform and could be considered a 'purple team' talk. Multiple live demos are planned, most of them ending in a guest-to-host escape and a root shell.
Balázs Bucsay - XFLTReaT: Building a Tunnelhacktivity
XFLTReaT is an open-source tunnelling framework that handles all the boring stuff and offers the capability to the users to take care of only those things that matter. It provides significant improvements over existing tools. From now on there is no need to write a new tunnel for each and every protocol or to deal with interfaces and routing. Any protocol can be converted to a module, which works in a plug-and-play fashion; authentication and encryption can be configured and customised on all traffic and it is also worth mentioning that the framework was designed to be easy to configure, use and develop. In case there is a need to send packets over ICMP, RDP or SSH then this can be done in a matter of minutes, instead of developing a new tool from scratch. The potential use (or abuse) cases are plentiful, such as bypassing network restrictions of an ISP, the proxy of a workplace or obtaining Internet connectivity through bypassing captive portals in the middle of the Atlantic Ocean or at an altitude of 12km on an airplane.
This framework is not just a tool; it unites different technologies in the field of tunnelling. It will be show how to tunnel data over a Windows jumpbox utilising RDP (including the dirty low level "secrets") or how to exfiltrate data over ICMP from barely secured networks. We have simplified the whole process and created a framework that is responsible for everything but the communication itself, we rethought the old way of tunnelling and tried to give something new to the community. After the initial setup the framework takes care of everything. With the check functionality we can even find out, which module can be used on the network, there is no need for any low-level packet fu and hassle. I guarantee that you won’t be disappointed with the tool and the talk, actually you will be richer with an open-source tool.
Gabrial Cirlig & Stefan Tanase - Smart Car Forensics and Vehicle Weaponizationhacktivity
As “smart” is becoming the new standard for everything, malicious threat actors are quick to capitalize on the insecurity of IoT devices. Hackers compromising your network and spying on you is not something new in the world of personal computers, but definitely an emerging threat in the world of personal cars.
Csongor Tamás - Examples of Locality Sensitive Hashing & their Usage for Malw...hacktivity
Several tools has been proposed for malware classification and similarity detection of binary malware samples, however none of them can solve all issues. In my presentation, I'll cover the problematics of Locality Sensitive Hashes and provide some experimental information about the comparison of different LSH algorithms. SSDEEPS's base algorithm, spamsum was originally designed for spam email detection. Although it discoveres some similarity between binaries, it basically needs large equal pieces of the byte code. This only happens rarely and can easily be altered. One of the contenders, TLSH (TrendMicro Locality Sensitive Hash) is a more stable similarity matching process. I'm going to present the results of the comparison on a smaller size samples set (~30k samples). Using LSHs is easy and doesn't require huge computational resources so after the process was deemed useful and effective it was extended to a large malware database of multiple hundreds of terabytes of samples. The experiments focus on ransomware sample classification, so I'm also going to present some details related to hunting for fresh unknown malware samples of known groups.
Matthias Deeg - Bypassing an Enterprise-Grade Biometric Face Authentication S...hacktivity
Biometric authentication systems have long, checkered history in IT security and are regarded as a highly controversial technology. Many manufacturers and users love them because of their usability and the personal touch they give to human-computer interaction when it comes to an often annoying but necessary task like user authentication. Other people hate them because of data privacy and security concerns. Despite all the controversy, biometric authentication systems are still here and they seem to stay.
In fall 2017, SySS GmbH started a research project concerning the enterprise-grade face authentication system Microsoft Windows Hello Face Authentication based on near infrared technology.
In our talk, we will present the results of our research project concerning the enterprise-grade face authentication system Windows Hello Face Authentication by Microsoft based on near infrared and visible light and will demonstrate how different versions of it can be bypassed by rather simple means.
Gergely Biczók - Interdependent Privacy & the Psychology of Likeshacktivity
The Facebook/Cambridge Analytica case headlined technical news the whole Spring of 2018. This case is not the first (and certainly not the last) that demonstrates privacy issues with Facebook and the ecosystem around it; yet, it gained notoriety because of its scale and alleged direct effect on the outcome of the US presidential election. In this talk we look behind the scenes and under the hood and analyze the IT, economic, psychological and legal background necessary to understand the full impact of the Cambridge Analytica case. We touch upon the underlying economic theory on externalities that defines interdependent privacy and sets the scene at a high level; the permission system of the Facebook API that enabled the collection of personal data at scale; the breakthrough psychology research that enabled the use of these data to influence political elections; and the legal impact through the lens of the GDPR.
Paolo Stagno - A Drone Tale: All Your Drones Belong To Ushacktivity
In 2013, DJI Drones quickly gained the reputation as the most stable platform for use in aerial photography and other fields. Since then Drones have increased their field of application and are actively used across various industries (law enforcement and first responders, utility companies, governments and universities) to perform critical operations on daily basis. As a result of that, Drones security has also become a hot topic in the industry.
This talk will provide a comprehensive overview of the security model and security issues affecting the underlying technologies, including existing vulnerabilities in the radio signals, Wi-Fi, Chipset, FPV system, GPS, App and SDK. As part of the presentation, we will discuss the architecture of one of the most famous and popular consumer drone product: the DJI Phantom 3. This model will be used to demonstrate each aspect of discovered security vulnerabilities, together with recommendations and mitigations.
A special focus will be on the recent changes and countermeasures DJI has applied to the firmware of its products in order to harden the security, following the recent accusations and the US Army ban. While the topic of hacking drones by faking GPS signals has been shared before at major security conferences in the past, this talk will extend these aspects to include geo-fencing and no fly zones abuses.
Jack S (linkcabin) - Becoming The Quiz Master: Thanks RE.hacktivity
linkcabin aims to discuss the journey of reverse engineering a pub quiz machine, to a point of emulation. By reverse engineering the software, lessons have been learnt in implementation of security, limits in 'security by obscurity' software solutions and how complex actual machines which involve betting are. After reverse engineering parts of the machine, and coming from a threat intelligence background, it becomes clear how similar software and malware developers minds really are for functionality.
While still developing software for an archaic operating system, much like critical infrastructure around the world, it becomes hard to balance both security and functionality.
Zoltán Balázs - Ethereum Smart Contract Hacking Explained like I’m Fivehacktivity
Mining. Ethereum. Smart Contracts. Gas. Solidity. DAO. These words had no or a different meaning 5 years ago. But now these are the foundations of something exciting and powerful. But with great power comes great responsibility. Designing and implementing Smart Contracts are like encryption protocols. Everyone can come up with one which looks secure from the developer’s perspective, but only a few can design and implement one which is really safe.
But how can one hack Smart Contracts? In order to understand this, I will explain the meaning of all of these words in the Ethereum world from the ground-ups with real life analogies. Once the basic building blocks are explained, I will guide you into the world of hacking Smart Contracts. After attending this presentation, everyone will understand how a recursive call can burn 250M USD on the DAO and how developers can create a parallel universe where this never happened. Reinit? Multi-signature wallets? The Parity hack? All of this is simple once the basics are founded.
Warning: case studies from recent real-life hacks and live interaction with Smart Contracts are included. And Cryptokitties. Meow.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

15. AEM Dispatcher
• Module for Web Server (Apache, IIS)
• https://www.adobeaemcloud.com/content/companies/public/adobe/dispatcher/dispatcher.
html
• Provides security (~WAF) and caching layers
15/110
16. AEM Dispatcher
• In theory … a front end system offers an extra layer of security to
your Adobe Experience Manager infrastructure
• In practice … it’s the only security layer!!!
• Admins rarely keep all components on Publish updated and securely
configured
16/110
28. Add multiple slashes
• ///etc.json instead of /etc.json
• ///bin///querybuilder.json instead of /bin/querybuilder.json
28/110
29. Using SSRF
• We need SSRF in a component that is allowed by AEM
dispatcher policy
• Effective way to bypass AEM dispatcher!
29/110
30. Things to remember
• Usually AEM dispatcher is the only security layer
• Usually it’s easy to bypass AEM dispatcher
• AEM admins usually fail to configure Publish instance securely and
install updates timely
…
• Profit!

• Or guess node names: /content, /home, /var, /etc
• Dump props for each child node of jcr:root
• /content.json or /content.5.json or /content.-1.json
42/110
43. DefaultGetServlet – What to grab
• Interesting nodes
• /etc – may contain secrets (passwords, enc. keys, …)
• /apps/system/config or /apps/<smth>/config (passwords, …)
• /var – may contain private information (PII)
• /home – password hashes, PII
• Interesting props – contain AEM users names
• jcr:createdBy
• jcr:lastModifiedBy
• cq:LastModifiedBy
