DeepSec 2022 Talk: Post-quantum Verkle Signature Scheme – Maksim Iavich

Sanna/ August 26, 2022/ Conference

We expect mass production of quantum computers in the near future. Quantum computers can easily break cryptographic schemes that are used in practice. Thus, classical encryption systems become vulnerable to attacks using quantum computers. There are research efforts to find encryption schemes that are resistant to attacks using quantum computers. Digital signatures are an important technology in securing the Internet and other IT infrastructures. A digital signature provides the authenticity, integrity, and identification of data. We use digital signatures in identification and authentication protocols. So, these secure digital signature algorithms are crucial in terms of IT security. Today, in practice, digital signature algorithms such as RSA, DSA, ECDSA are used. However, they are not quantum stable, as their safety relies on large composite integers, complex factorization and the computation of discrete logarithms. We asked

DeepSec 2022 Talk: GitHub Actions Security Landscape – Ronen Slavin

Sanna/ August 25, 2022/ Conference

GitHub Actions, the recent (from 2018) CI/CD addition to the popular source control system, is becoming an increasingly popular DevOps tool mainly due to its rich marketplace and simple integration. As part of our research of the GitHub Actions security landscape, we discovered that in writing a perfectly secure GitHub Actions workflow, several pitfalls could cause severe security consequences. For example, many developers would use event input data to improve their workflow process. However, this data could be controlled by an attacker, and potentially compromise the build process. Unless the developers are proficient in the depths of GitHub best-practices documents, these workflows would have mistakes. Such mistakes are costly – and could cause a potential supply chain risk to the product. During the talk, we’ll walk you through our journey on how we found

DeepSec and DeepINTEL 2022 Schedule – Reviews almost done

René Pfeiffer/ August 15, 2022/ Conference, Training

The yearly review of submissions is the hardest task of the year. Thanks a lot for your contributions. DeepSec would need to be a full week to accommodate all submitted material. Thanks a lot! We are still stuck in the final reviews, so it will take a week or two to fill all the slots. You may have noticed that the schedule on our website is already alive and kicking. There will be some more rearrangements regarding the presentation slots. The DeepINTEL schedule is available on request since DeepINTEL is a TLP:AMBER event. We have some interesting insights into current campaigns and the capabilities of selected adversaries for you. Effective defence needs well-prepared data and reconnaissance. So we highly recommend attending DeepINTEL 2022. Looking forward to see you in Vienna!

Press Release: Spy Tools must not become Standard Software

Sanna/ August 3, 2022/ Press

DeepSec security conference warns of the growing market for spy tools. Information technology has gained a new acronym: Private-Sector Offensive Actor (PSOA). PSOA means something like a private-sector offensive opponent. The specific case of a PSOA has also reached Austria because of research by Microsoft®. An Austrian company is accused of being involved in digital attacks on Microsoft® customers in Europe and Central America. The case illustrates that spyware continues to be developed and used as a dangerous threat to information security. The DeepSec security conference taking place in November repeatedly warns against such technology and will deal specifically with the details of industrial espionage. Threatening security as a business model Bypassing security measures is a lucrative business model. Companies are active in this field all over the world. Some buy knowledge of security

Translated Article: German Cyber Security Strategy without Security

Sanna/ July 27, 2022/ Stories

Deutsche Cybersicherheitsstrategie ohne Sicherheit by Erich Moechel for fm4.ORF.at The new German Interior Minister Nancy Faeser (SPD) is continuing the cyber course of her predecessor Horst Seehofer (CDU), which according to independent experts has been completely misguided. The professional world “is not amused”. Parallel to the finalization of the new EU directive on cyber security (NIS2), Germany’s new cyber security strategy was presented in Berlin. The European directive, which was negotiated unusually quickly, was welcomed almost unanimously by experts. The new German cyber security strategy, on the other hand, has been consistently criticized by experts since its publication. As a closer look shows, it is neither new nor a security strategy. First and foremost, new powers are being distributed to police authorities and secret services. Trojans instead of cyber security As the table of contents already

DeepSec 2022 Training: Exploiting Race Conditions – Dawid Czagan

Sanna/ July 25, 2022/ Training

A race condition attack is one of the most dangerous and underestimated attacks on modern web applications. It’s related to concurrency and multithreading. As a result of this attack an attacker, who has $1000 in his bank account, can transfer more than $1000 from his bank account. This is just one example, but it clearly shows how dangerous this attack is. In a free video Dawid Czagan (DeepSec instructor) will show you step by step how this attack works and will tell you how to prevent this attack from happening.

DeepSec 2022 Training: Bypassing Content Security Policy via ajax.googleapis.com – Dawid Czagan

Sanna/ July 21, 2022/ Training

Content Security Policy (CSP) is the number one defensive technology in modern web applications. Many developers add ajax.googleapis.com to CSP definitions, because they use libraries from this very popular CDN in their web applications. The problem is that it completely bypasses the CSP and obviously you don’t want that to happen. In a free video, Dawid Czagan (DeepSec instructor) will show you step by step how your CSP can be bypassed by hackers.

Press Release: Ransomware Attacks Are No Force Majeure

Sanna/ July 7, 2022/ Press

DeepSec security conference reminds you of basic IT protection and secure system architecture. Malware attacks that encrypt data of victims seem to have increased recently. In fact, these ransomware attacks are only part of an evolution among the attackers. Attack software moves with the times. An important reason for the accumulation is the standstill in defense. This year’s DeepSec security conference offers exchange with experts and high-quality further training for protecting your own IT. Basic Misunderstandings Comparing the reports of incidents involving ransomware attacks, one might conclude that these are inevitable natural events. Of course, that’s not the case. If one sticks to the biological analogy of the virus, a favorable combination of prerequisites for the infestation of ransomware results. In the beginning, there is always a deception in the form of a fake
