DeepSec 2020 Talk: Security of Home Automation Systems – A Status Quo Analysis For Austrian Households – Edith Huber, Albert Treytl

Sanna/ September 28, 2020/ Conference/ 0 comments

Home Automation System (HAS) are a growing market, which is very diverse ranging  from consumer electronics like TVs, mobile phones and gaming consoles via WLAN connected sensors, power plugs or lightbulbs to building automation devices for HVAC systems or access solutions. Beside “classical” network technologies IoT technologies gain increasing spread and importance. This paper presents results of a representative survey analysing the security awareness and perception as well as susceptibility to cybercrime of HAS users in Austria. The aim of this survey is to investigate the spread of the device types, cybercrime attacks and security risks. These results are compared with technical vulnerabilities of such devices to identify relevant security risks and countermeasures. Additionally, a concept to protect sensor values directly in the analogue circuit is presented as an outlook to ongoing research. We asked Edith and Albert a few more questions about their talk.   Please tell us the top facts about your talk. The most common HAS are Smart TV, voice assistants and surveillance cameras, but many other applications are on the rise. Respondents of the survey say

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

Sanna/ September 25, 2020/ Conference/ 0 comments

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/ 0 comments

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

DeepSec2020 Talk: The Art Of The Breach – Robert Sell

Sanna/ September 16, 2020/ Conference/ 0 comments

The Art of the Breach is designed to be a journey for anyone interested in physical security. Robert takes the audience on a trip from the public sidewalk outside a target organization all the way through to the executive filing cabinet in the President’s office. While many physical security talks focus strictly on the information security aspect of breaching, Robert will combine this with techniques used by first responders to enter a building. While social engineering and lock picking will be discussed, Robert will also outline the third option of forced entry. During this adventure, Robert discusses everything from successful reconnaissance to ensuring an easy exit afterwards. Robert spends time at each step to go over the various options for moving forward. Some of these options are easy and straightforward while others require preparations

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

Sanna/ September 14, 2020/ Conference/ 0 comments

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/ 0 comments

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/ 0 comments

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/ 0 comments

[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

DeepSec 2020 Talk: Security Model Of Endpoint Devices – Martin Kacer

Sanna/ September 1, 2020/ Conference/ 0 comments

Have you ever asked these questions? You are using the latest mobile and using your laptop with the latest and patched OS, running antivirus: Do you need to worry about security? Isn’t there still something broken in the entire security and permission model? Why can the desktop application, that is not an internet browser, access and communicate by using any IP address? Why can the application access your whole filesystem and collect the files from there? Why can an android app with internet permission communicate using any arbitrary IP, even a private one? Why can the app communicate by using different domains? Isn’t the app market ecosystem creating a friendly environment for botnets? This talk will shed some light on these issues and propose some mitigation strategy. We have asked Martin a few more

Press Release: Intensive Courses for crisis-proof Digitisation taking place in Vienna

Sanna/ August 28, 2020/ Conference, Press/ 0 comments

DeepSec security conference focuses thematically in depth on critical dangers for IT. As is well known, the digital world never sleeps. The last few months have shown that society and the economy are more dependent than ever on globally networked technology. The worldwide spread of SARS-CoV-2 has given telecommunications an enormous boost. The home office, already known before, teleconferencing systems and internet applications had to stand in for physical meetings and enable the exchange of information. As the use of these technologies increased sharply, security problems were of course discovered. Zoom is a prominent example. However, only the tip of the iceberg was analysed. Many vulnerabilities are still waiting to be discovered around the world. Anyone who demands more digitisation is actually talking about information security. Precisely for this reason, the DeepSec Security Conference

Press Release: Digital Infrastructure should integrate Malware

Sanna/ July 22, 2020/ Conference, Press, Security/ 0 comments

The German government wants to force Internet providers to install malicious software and intercept network traffic. Since the 1990s, there has been a constant struggle between authorities and security experts. One side wants to make digital infrastructure, especially data transport and communication, as secure as possible for business and society. The other side constantly strives for back doors to intercept data and correspondence. The fight for access to secure data transmissions, originally titled “Crypto Wars” is entering the next round. The German federal government has created a draft law that is intended to legally force Internet providers and companies with related activities to distribute malware and manipulate network traffic. In future, the installation of apps on smartphones or automatic software updates can compromise computer systems. This destroys the basis of digitalisation – with far-reaching

Translated Article: EU Council of Ministers discusses Back Doors in Encryption again

Sanna/ July 21, 2020/ Security, Stories/ 0 comments

EU-Ministerrat diskutiert wieder Hintertüren in Verschlüsselung by Erich Moechel for fm4.ORF.at Gilles de Kerchove, EU’s anti-terror coordinator, is once again working against secure encryption per se. Since these new demands by law enforcement officials on the EU Council of Ministers are nowhere openly accessible, this confidential Council document is published in full by FM4. The corona virus pandemic has led to a surge in teleworking worldwide. Instead of behind firewalls in secure corporate networks, millions of employees worldwide work from insecure home offices. The only real protection is the end-to-end encryption (E2E) of the data traffic. In the middle of this scenario, the “Five Eyes” secret service alliance is starting the next phase of its global campaign against secure encryption. Again, police law enforcement is used as a vehicle. After the United States, the European protagonist
