DeepSec 2023 Talk: KENOUGH: More Than Just a Pretty Interface – Daniel Kroiss & Stefan Prinz

Sanna/ October 9, 2023/ Conference/ 0 comments

The vast majority of organizations on our planet are SMEs who do not have the capability to leverage professional Threat Intelligence Tools or even have Threat Intelligence Teams. They continuously struggle to prioritize their efforts fixing security problems but are typically not focusing on the right stuff. Not all threat actors are equally likely to penetrate your organization. Therefore, not all TTPs are equally likely to be leveraged against you. MITRE ATT&CK is the de facto standard in researching current TTPs and figuring out how to detect and prevent them from happening. We created a small but powerful tool based on MITRE ATT&CK to easily figuring out connections between Threat Actors, malware, TTPs and their relevance to your industry to help you figure out what to focus on. The tool is specifically built for

DeepSec 2023 Talk: Post-quantum digital signatures using Verkle tree and AI in post-quantum cryptography – Maksim Iavich

Sanna/ October 3, 2023/ Conference/ 0 comments

Recent advancements in quantum computing research have made significant progress. If we achieve a functional quantum computer, it has the potential to undermine the security of current public key cryptosystems, which are widely integrated into commercial products. Although there have been proposed solutions to counter quantum attacks, these solutions currently grapple with security and efficiency concerns in everyday use. This talk focuses on exploring hash-based digital signature techniques, particularly those rooted in Merkle tree structures. The research deeply investigates the viability of Verkle trees and vector commitments, introducing pioneering concepts within this field. At DeepSec I will present a novel post-quantum digital signature, using modern technologies, such as Verkle tree. I will talk about the working methology of making the signature post-quantum secure. I will describe the attack on post-quantum digital signatures using machine

DeepSec 2023 Talk: The Evolution of Linux Binary Exploitation: From Outdated Techniques to Sophisticated Modern Attacks – Ofri Ouzan & Yotam Perkal

Sanna/ September 28, 2023/ Conference

In the ever-evolving realm of cybersecurity, the cat-and-mouse game between attackers and defenders continues to intensify. To safeguard critical systems against malicious exploitation, the hardening of binary files has emerged as a fundamental security measure. However, no security measure remains impervious to threats, and binary hardening techniques face ongoing challenges. This talk aims to shed light on the significance of binary hardening as a countermeasure against growing vulnerabilities. Through a comprehensive examination, we explore both traditional and contemporary binary exploitation techniques, providing real-world insights into modern exploiting methodologies that bypass protective mechanisms implemented through binary hardening. Our research addresses the lack of accurate and complete sources of information on binary hardening, emphasizing the importance of understanding ELF file structure and attacker avoidance strategies. By encouraging vigilance among developers and defenders, we aim to raise

DeepSec 2023 Talk: RansomAWARE in 2023 – Steph Shample

Sanna/ September 26, 2023/ Conference

Ransomware’s explosion has been sustained for years. As tech changes, so too do the actor TTPs. It’s imperative to explore the 2023 mindset of ransomware actors: they are going after “target rich, cyber poor” industries that will make them money by selling data, exploiting the victims they hit as well as the partners and third party services linked to the victims. While double-, triple-, and quadruple- extortion practices are still around, actors are also adapting/changing their encryption processes to better emulate protective services such as anti-virus and file scanning software to blend in and provide no red flags to technical and cyber practitioners. This allows for a long-term, stealth presence in networks, which facilitates lateral movement to collect as much information as possible. We asked Steph a few more questions about her talk. Please

DeepSec 2023 Talk: I Just Wanted to Learn the Water Temperature… – Imre Rad

Sanna/ September 25, 2023/ Conference

The story started as a hobby project: I was about to retrieve the current temperature of a non-smart water heater in my apartment. To not void the warranty, I was looking for a non-intrusive solution that purely relies on off-the-shelf smart home gadgets only. Understanding the undocumented APIs of these IoT devices required reverse engineering the corresponding official mobile applications and eavesdropping on the network communication between them and the cloud management services. Researching this uncovered design flaws in the pairing protocol and vulnerabilities in the implementation that allowed attackers to steal victim sessions and to impersonate these devices for a life-time. We asked Imre a few more questions about his talk. Please tell us the top 5 facts about your talk. Recognizing digits on a still picture is far from easy (regardless the

DeepSec 2023 Talk: I’m Ok, You’re Ok, We’re Ok: Living with AD(H)D in Infosec – Klaus Agnoletti

Sanna/ September 22, 2023/ Conference

[This is a different topic than information security. Klaus’ presentation was included in the DeepSec 2023 schedule, because it deals with the way some of us are dealing with the individual thought processes. The work environment doesn’t fit for everyone.] I was diagnosed with AD(H)D almost three years ago, aged 44. Getting the diagnosis and being able to get proper medicine meant the world to me; suddenly I understood all those symptoms and I could function remarkably better. Better understanding also meant that I got more insight to why it was becoming increasingly harder for me to get and keep a job. So something had to happen. I’ve been an InfoSec professional for almost 20 years but after my diagnosis I moved to community marketing which basically meant doing the spare-time thing I love

DeepSec 2023 Press Release: Digitalisation Requires More Than Just Technology – DeepSec Conference Combines Digitalisation With IT Security Trainings

Sanna/ September 20, 2023/ Conference, Press

Digitalisation is a great opportunity and has arrived in all areas of society. However, there is more to it than using digital data and computer systems. Processes and ways of working need to be adapted. In addition, information security must be considered throughout, from design to implementation. The DeepSec conference again has extensive training on this topic in its programme. Digitalisation generates opportunities and markets The basic idea of digitalised processes in companies and administration is simplification through the use of IT infrastructure. Data is more easily available. Documents can be searched and found more easily. This also means that more information is available in digital form. The opportunities and markets generated by this are not all legal. In 2022, data from one billion Chinese nationals was copied. In 2018, the Indian government reported

DeepSec 2023 Talk: WEFF : p2p Communication without Third Party – Nikolaos Tsapakis

Sanna/ September 19, 2023/ Conference

References in public available literature pertaining to a completely serverless connection method between two peers behind routers implementing NAT are scarce. In this talk, we are describing a more generic method for NAT traversal that requires no intermediate server and relies on a multiple port testing method which resembles a brute force attack. We have created a proof of concept for verifying and showing our results. This talk relates to p2p communication without the need for a third party (intermediate server or other) for initiating the communication. We asked Nikolaos a few more questions about his presentation. Please tell us the top 5 facts about your talk. Privacy Decentralized communications Secure communications Easy to implement Fun to use How did you come up with it? Was there something like an initial spark that set

DeepSec 2023 Talk: Skynet wants your Passwords! The Role of AI in Automating Social Engineering – Alexander Hurbean & Wolfgang Ettlinger

Sanna/ September 18, 2023/ Conference

We techies love solving problems with cool technology, to where we attempt to implement the economy in code. Although important in general, we know that, for example, blockchain, cryptography, and Secure Software Development Life Cycle (SSDLC) are irrelevant when the user enters their credentials on a phishing site. From an attacker’s point of view, though, we see that modern technologies such as artificial intelligence are immensely beneficial to attack one of the weakest links in security – humans. We will explore how modern technologies, for instance DeepFakes, Deep Neural Networks (DNNs), and Transformers, can be misused by bad actors. We will explore some interesting ideas for attacks, discuss their practical feasibility and show implementations of some of these attacks. We will also look at approaches to detect and defend against AI-powered attacks. We asked
