DeepSec 2020 Talk: Scaling A Bug Bounty Program – Catalin Curelaru

Sanna/ October 8, 2020/ Conference

Hacking, hackers and bug bounties are really getting constant headlines into the mainstream news. In the past few years we have seen an impressive growth in Bug Bounty Programs and at this point we really need to ask: Is a Bug Bounty Program a new layer to secure applications? Implementing a Bug Bounty Program can be challenging and requires some understanding of the nuances of how to make it successful or not. Actually, running a successful bug bounty program starts far before it is launched officially. What are the prerequisites and why can we consider a bug bounty program as a layer for your Application Security Program? How do you measure if you are successful or not and what are the KPIs? When are you ready to start such a program? Based on the

DeepSec 2020 Press Release: Digital information security has human weaknesses – DeepINTEL Security Intelligence Conference discusses strategic IT security in Vienna.

Sanna/ October 7, 2020/ DeepIntel

In the last few decades, everyday professional and private life has been increasingly permeated by modern technologies and networked communication. In addition to many conveniences, this has also created difficult challenges for information security. Therefore more and more complex technical solutions are celebrated at many security conferences. The problem with the problems that are to be solved in this way: The human factor and its weak points, which can do totally without digitization. The DeepINTEL conference therefore deals with the interrelationships and strategic background of information security in order to minimize threats and improve protection in the long term. Errors in the System are part of the Foundation Reports of data leaks and spectacular break-ins appear in the news again and again. Unfortunately, only the results are shown.

Translated Article: Urgent Warning of Back Doors in Citrix Systems

Sanna/ October 6, 2020/ Stories

Dringende Warnung vor Hintertüren in Citrix-Systemen by Erich Moechel for fm4.ORF.at An unknown number of these VPN gateways, which protect important networks in Austria such as electronic official traffic, ministries, supermarket chains, etc., are infected with malware. Ransomware blackmailers are now attacking one network after another. After the huge security gap in Citrix dial-up systems (“Shitrix”) at the beginning of the year, the consequences are now coming to light. The German security consultants HiSolutions have recently discovered a number of encryption attacks that were carried out through back doors installed at the time. Large company and authority networks are affected, which, like the electronic file traffic of the Republic (ELAK), were open for weeks over the turn of the year. Almost all of these “VPN gateways” were backed up by software updates much too

DeepSec 2020 Talk: RedTeamOps – Mert Can Coskuner, Caglar Cakici

Sanna/ October 3, 2020/ Conference

Red team operations involve many skills, the operation requires a lot of monitoring, consolidating and caution. In order to perform red team operations faster and stealthier, without thinking about the infrastructure, every team has its’ own habits and standards. However, there is a problem with those habits and standards: There are tons of tools but no operation management, No aggregation between these tools, When OPSEC fails due to problems above or any other reason, it’s essential to possess the capability of maintaining robust infrastructure which can be recreated if discovered, and more importantly, without any issues upon deployment. In this talk, infrastructure challenges we face as a red teamer will be discussed. Along with challenges, a solution will be proposed based on DevOps practices such as: Design your infrastructure based on the standards and

DeepSec 2020 Talk: Efficient Post-quantum Digital Signature – Maksim Iavich (DeepSec Scholar 2020)

Sanna/ September 25, 2020/ Conference

Active work is being done to create and develop quantum computers. Traditional digital signature systems, which are used in practice, are vulnerable to quantum computers attacks. The security of these systems is based on the problem of factoring large numbers and calculating discrete logarithms. Scientists are working on the development of alternatives to RSA, which are protected from attacks by quantum computer. One of the alternatives are hash based digital signature schemes. Merkle digital signature scheme is the very promising alternative to the classical digital signature schemes. It must be emphasized, that the scheme has efficiency problems and can not be used in practice. Major improvements of the scheme lead to security vulnerabilities. I will show that Merkle uses hash functions many times. I will offer the improved implementation of the hash function. I

DeepSec2020 Press Release: Industrial control systems put to the test. DeepSec conference organizes forum for the protection of Industrial Control Systems (ICS)

Sanna/ September 17, 2020/ Press

When one talks about digitization, one usually means networked control and measurement systems. The associated technical term Industrial Control Systems (ICS) covers a wide area and extends into Industry 4.0, in which information security plays a very important role. The right design and secure code thus become part of critical infrastructure. This year’s DeepSec security conference offers a forum for the first time – the ICS Village – in which developers and security experts can exchange ideas and experience. The stated goal is to design control systems securely, to implement them robustly, to test them properly, and to protect these systems appropriately. Servant spirits of the infrastructure Control systems and automated process control normally lead an invisible existence. Production lines, building management, lighting control, traffic systems, industrial plants or power supply are indispensable parts

DeepSec 2020 Talk: Abusing Azure Active Directory: Who Would You Like To Be Today? – Dr. Nestori Syynimaa

Sanna/ September 14, 2020/ Conference

This will be one of the few online talks held at DeepSec. Dr. Nestori Syynimaa covers the wonderful world of Azure AD and third-party code. Azure AD is used by Microsoft Office 365 and over 2900 third-party apps. Although Azure AD is commonly regarded as secure, there are serious vulnerabilities regarding identity federation, pass-through authentication, and seamless single-sign-on. In this session, using AADInternals PowerShell module, I’ll demonstrate the exploitation of these vulnerabilities to create backdoors, impersonate users, and bypass MFA. The purpose of this session is to raise awareness of the importance of the principle of least privilege and the role of on-prem security to cloud security. We asked Dr. Nestori Syynimaa a few more questions about his talk. Please tell us the most important facts about your talk. Azure AD acts as an

DeepSec 2020 Talk: Caught in the Middle with You: Examining the Implications of Adversary Midpoint Collection – Joe Slowik

Sanna/ September 9, 2020/ Conference

Information security typically focuses on endpoint exploitation and manipulation. Endpoints are where our tools reside (EDR, log sources, and similar artifacts), and where we are most comfortable operating as these are the systems we interact with on a daily basis. However, adversaries increasingly migrate attacks to cover “midpoint” techniques (DNS manipulation, router exploitation, and traffic shaping mechanisms) to circumvent both endpoint and network defenses. Such actions shift operations to either devices we are unfamiliar with – routers, VPN concentrators, and similar devices – or systems and services completely outside our control – ISP equipment and fundamental Internet functionality. Although media stories highlighting such attacks exist, most threat analysis provides little information on the implications of such attacks or defensive strategies to meet them. By analyzing revelations emerging from various NSA-related leaks, followed by consideration

DeepSec 2020 Talk: EPP/EDR – Unhooking Their Protections – Daniel Feichter

Sanna/ September 4, 2020/ Conference

More and more we see in our penetration tests, that companies do not just rely on the traditional endpoint protection (EPP). Instead they began to add an additional EDR to the existing EPP or they use an EPP/EDR combination from different vendors like Microsoft, CrowdStrike, Endgame etc. Compared to EPP, an EDR is not designed for the prevention of malware, but for detection, response and hunting. EDR systems have a high process visibility at the endpoint. This makes it possible to conduct malware analysis based on the monitored behaviour. For that some EPP/EDR products under Windows rely on the technique API-Hooking. API-Hooking is a method to check executed code (via APIs) for malicious content by interception. For this purpose, the EPP/EDR software injects its own .dll into the address memory of a process. In

DeepSec 2020 U21 Talk: Protecting Mobile Devices from Malware Attacks with a Python IDS – Kamila Babayeva, Sebastian Garcia

Sanna/ September 2, 2020/ Conference

[Editorial note: We are proud to publish the articles about the U21 presentation slot for young researchers. The U21 track is a tradition of DeepSec. We aim to support (young) talents and give them a place on the stage to present their ideas and to gain experience.] Technology poses a risk of cyber attacks to all of us, but mobile devices are more at risk because there are no good detection applications for phones, and because they are the target of many novel attacks. We still don’t have a good idea of what our phones are doing in the network. To be better protected, mobile devices need better detection solutions from our community. In this talk I will present the development of Slips, a Python-based, free software IDS using machine learning to detect attacks
