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

EU-Kontrollausschuss blockt Verordnung zur Chat-Überwachung by Erich Moechel for fm4.orf.at [We have translated this article, because we have criticised client side scanning and introducing backdoors to circumvent encryption in past articles. Erich Möchel has an update on the current EU initiative to make encryption useless.]. A leaked report from the Commission’s control committee shows that officials from the Commission’s interior department have not presented a legally compliant draft in two years. The publication of the ordinance on the automated monitoring of chats, which was announced at the end of March, has already been postponed again. This ordinance, ostensibly aimed at combating child abuse, is now 18 months behind schedule. A recent leak now shows the reason for this series of postponements. The officials responsible for the Commission’s draft could not come up with a text

Translated Article: Internet Traffic in Russia will be Rerouted

Sanna/ March 17, 2022/ Stories

Der Internetverkehr Russlands wird umgeroutet by Erich Moechel for fm4.orf.at With Lumen and Cogent, the leading transit carrier and the number three are just exiting the Russian market. Apparently, this doesn’t happen voluntarily and, above all, not as quickly as announced. After the media sector and the stock exchange, the western sanctions are now hitting the Russian IT industry with full force. With Cogent and Lumen, two of the top five international Internet carriers are in the process of cutting off their major customers in Russia one after the other. Market leader Rostelecom, all mobile phone companies and the Internet group Yandex are losing their strongest connections to the world. On Friday, the London Internet Exchange announced that Rostelecom traffic would no longer be routed. All of this is a first in the history of

DeepSec 2021 Talk: Analyzing Radicalization on the Internet – Method and Results of the COMRAD-Project – Dr. Andreas Enzminger & Dr. Jürgen Grimm

Sanna/ November 17, 2021/ Conference, Internet

Incitement, radicalization, and terror are the buzzwords that currently concern us the most. Right-wing and left-wing extremist groups or religious fundamentalists act as fire accelerators for extremist tendencies, even leading to the use of political violence. In this way, they can also endanger the value-based foundations of democracy in the medium and long term. Although much discussed, the role of the media, especially social media, in radicalization within society remains conceptually and empirically unclear. While there are several case analyses based on violent events, systematic studies have yet to be conducted. To fill this gap, the COMRAD project is dedicated to researching radicalization tendencies in cyberspace, focusing on psychosocial, ideological, and communicative conditioning factors. The focus is on the “open space” of politically left-wing, right-wing, or Islamic Facebook groups, in which recruitment strategies and

DeepSec2021 Talk: QKD-based Security for 5G and Next Generation Networks – Sergiy Gnatyuk, PhD. DSc.

Sanna/ November 16, 2021/ Conference, Security

Modern information and communication technologies (ICT) implementation in all spheres of human activity, as well as the increasing number and power of cyber-attacks on them make the cyber security of the developed digital state vulnerable and weak. Cyber-attacks become targeted (so-called APT-attacks) and attackers carefully prepare them, analyzing the identified vulnerabilities and all possible ways of attack. The security and defense capabilities of the state are considered in an additional fifth domain titled cyberspace (after land, air, water and space). World`s leading states develop strategies to protect cyberspace, create cyber troops, develop and test cyber weapons. A significant number of cyber-attacks today are aimed at critical infrastructures and government organizations. Traditional security methods (in particular, cryptographic algorithms) do not fully protect against all currently known attacks, they are potentially vulnerable to attacks based on

DeepSec2021 Talk: On Breaking Virtual Shareholder Meetings: How Secure is Corporate Germany? – Andreas Mayer

Sanna/ October 29, 2021/ Conference

The Covid-19 pandemic has had a major impact on annual general meetings (AGMs) of shareholders worldwide. Due to existing gathering restrictions the vast majority of AGMs shifted from physical to online voting events. Therefore, purely virtual AGMs emerged to the new normal where shareholders approve critical company decisions. But how secure are those virtual events really? In this talk, I will present a systematic large-scale study on the security of 623 virtual AGMs held by German companies in 2020 including corporations listed in stock indices such as DAX and MDAX. In 72% of all virtual AGMs analyzed, at least one of the three CIA triad security goals was compromised. Join my talk and I will take you on an enthralling journey through the nitty gritty details and pitfalls that lead to the severe vulnerabilities

DeepSec 2021 Press Release: Organized Espionage on Digital Devices. DeepSec Conference Warns: Searching for “Forbidden” Data on Clients Compromises Information Security.

Sanna/ October 25, 2021/ DeepIntel, Press

A basic principle of information security is access control. We are all used to the fact that data is only available to people and systems with the right authorizations. The discussion about the search for prohibited image files on Apple systems sparked the discussion about the so-called Client-Side Scanning (CSS) technology. Searching for specific content past access restrictions has always been an appealing shortcut. It is now clear that CSS leads to serious problems that endanger the basis of information security and do not bring the hoped-for benefits. Instead, there are additional security loopholes. Search of end devices Lately, the EU Commission and law enforcement authorities have repeatedly addressed the issue of circumventing secure encryption. In mathematical terms, we cannot carry strong encryption out without stored duplicate keys or deliberately weakening the technologies used.

DeepSec 2021 Talk: Building a Cybersecurity Workforce: Challenges for Organizations – Matthieu J. Guitton

Sanna/ October 23, 2021/ Conference

The shift of human activities from offline to online spaces has major impacts on organizations – either public or corporate – in terms of security, therefore creating a constantly growing need for cybersecurity experts. Although for small companies, expertise can come from external providers, large organizations need to build their own cybersecurity workforce. The limited number of higher education formations result for companies in tension in the employment market, and in the recruitment of people whose expertise is not primarily on cybersecurity. Furthermore, cybersecurity often focuses on technical aspects, and does not always deal enough with the human factor – while the human factor is critical for companies and other large organizations. This presentation will explore the challenges related to building a workforce in cybersecurity from the point of view of organizations. We will
