Press Release: Current Threats in Cellular Networks – DeepSec Security Conference offers Security Training in dealing with Current Cellular Technology

Sanna/ May 26, 2021/ Press, Training

In the past 40 years, cellular technology has achieved a veritable triumph. Availability, stability and data rates have increased significantly compared to the origins of 1G / 2G networks. The enthusiasm for security research in this area is not quite as enthusiastic. There are still weak points and tradeoffs in information security. At the first DeepSec conference in 2007, the weaknesses of A5 encryption were revealed. This year’s conference therefore again offers a two-day workshop on the security of current cellular technology. Basis of the communication society Many of the conveniences of modern life are inconceivable without cellular networks. The internet is almost always available. Communication is very easy even outside of cities, during leisure activities or when going for a walk, reception is of course required. The evolution of the technological generations up

Press Release: Low-tech Attacks. Critical Infrastructure poorly secured – Attacks against Colonial Pipeline used Standard Access Tools

Sanna/ May 20, 2021/ Press, Training

In May, the operator of the US Colonial Pipeline was the victim of a ransomware attack. After such reports, calls for better security and additional measures are always loud. In fact, analyzes of these attacks often reveal deficiencies in basic security. Often it is not even necessary to use complicated and sophisticated tools to attack critical infrastructure. Attackers like to use standard tools that are available everywhere so as not to attract attention. The lack of basic security makes it possible. Custom camouflage When defending your own systems and networks, it is necessary to know exactly what the infrastructure is like. Organized groups that attack companies research exactly what is being used at the target before the attack. According to this planning phase, only tools are used that are plausible to the victim and

Murder Board Blog Series: Chapter 4 – Trojan Horses or: State Hacking

Sanna/ May 17, 2021/ Internet, Security, Stories

Feeding Pigeons in the Park—Espionage Knowledge is power. Knowing nothing makes one envious when looking at the model of modern information societies. The natural application of networks that transport information is espionage. So the Internet early made acquaintance with it. The aspect of smuggling messages in and out of an area is obvious. It also involves breaking through security measures to gain access to protected information. Whereby large parts of our own information are much less protected than we would like or even be aware of. The e-mails mentioned above are always in plain text and therefore are visible to everyone. An unknown number of third parties read them on the way from sender to recipient and assess this information. And all the information we have in accounts on US platforms (photos, more or

Murder Board Blog Series: Chapter 3 – Serial Hackers: Organized Crime or Grand Theft Data

Sanna/ May 7, 2021/ Internet, Security, Stories

Motivations and Motifs of the “Cosa Data” Elevate data to a valuable commodity and it gets automatically traded, hoarded, stolen and counterfeited. We can use digital processes both legally and illegally, just like the economy in the physical world. However, cyber crime is about much more than data. Accounts with certain privileges also represent value because they act as a multiplier. For example, a simple e-mail account with stored contacts (address book or even the contact data in existing e-mails). This has several properties at once: Identity, trust and an archive of messages. The archive can be searched directly for valuable data. The identity can be used for fraud with the help of the trust of the contacts to get further access to more accounts and data. Motivation is—on balance—always something like a benefit

Murder Board Blog Series: Chapter 1 – Traces

Sanna/ April 23, 2021/ Stories

The Time Factor Traces are the “metadata” of an act, a course of action, a communication or even a presence or having been there. They show us that something happened, but often also how something happened. We consider traces always in retrospect, because they have to be there first in order to be considered. The time interval between the emergence of traces and their observation can vary. In 2017, for example, researchers investigated how Ötzi, a mummy from the ice of the Ötztal Alps, came to his death about 5,300 years ago and thus solved a murder with a slight time delay. But some traces also disappear. Not only the well-known traces in the sand … Also we can’t detect e.g. knockout drops in the victim’s blood already 24 hours after they drank them.

DeepSec 2021: A lack of software security paralyzes the economy in times of crisis – visit DeepSec 2021 to train your developers

Sanna/ April 20, 2021/ Development, Press, Training

In every crisis, one’s own infrastructure and logistics are put to serious tests. The COVID-19 pandemic illustrates this particularly drastically through the many structural failures in the past 12 months. They try to solve biological problems with smartphones, favor dead-end technologies such as blockchain, discover the lack of network expansion in recent decades and then panic and publish software applications that are only subjected to serious tests after they have been published. All these quick fixes are snapshots of a lack of sustainability. But the economy is dependent on stable solutions based on many years of experience, especially now. In November 2021, the DeepSec conference would like to give support to everyone who works with software through trainings and the transfer of experience from security researchers.

Translated Article: EU-US Summit Against Secure Encryption

Sanna/ March 31, 2021/ Legal, Stories

Gipfel EU-USA gegen sichere Verschlüsselung by Erich Moechel for fm4.ORF.at The agenda of the virtual meeting at a high-ranking official level in two weeks features pretty much all data protection-related topics that are currently controversial in Europe. Joe Biden’s appearance before the EU Council of Ministers will be followed by a two-day video conference on April 14th at the top level of officials in the field of justice and homeland security between the EU and the USA. Practically all currently controversial issues around data protection are on the agenda, from cross-border data access for law enforcement officers to joint action against secure encryption. This is also the case with the “fight against child abuse”, which is once again being instrumentalized for these general surveillance projects.

Translated Article: Further Wrangling in the Council of Ministers over Competences for Europol

Sanna/ March 30, 2021/ Discussion, High Entropy, Legal, Stories

Weiter Gerangel im Ministerrat um Kompetenzen für Europol by Erich Moechel for fm4.ORF.at A majority led by Germany and France does not even want to give Europol the power to initiate transnational investigations itself in the event of a major cyber attack. On Monday the EU Council of Ministers decided on an approach for a new cybersecurity strategy. A network of “Security Operation Centers” across Europe will form an early warning system against attacks, and a new “Joint Cyber Unit” will be responsible for crisis management. In addition, they want to promote strong encryption methods together – but with back doors for law enforcement officers. Whether this collection of buzzwords will actually become an EU-wide implemented strategy is very much in question. The ongoing discussions in the Council of Ministers about the planned new powers of

E-Privacy-Verordnung erlaubt Vorratsdaten und Nachschlüssel by Erich Moechel for fm4.ORF.at The most important EU regulation for the protection of privacy contains a license for data processing of all kinds without the consent of the user and allows political parties to spread spam mail. For four years the e-privacy regulation has been stuck in the EU Council of Ministers, but under the Portuguese presidency, it was possible to agree on a version for the first time. However, this version of the “Ordinance on the Respect of Privacy and the Protection of Personal Data” has been designed in such a way that Germany’s top data protection officer, Ulrich Kelber, sees “several red lines crossed at the same time”. In addition to the reference to data retention, which was rejected by the EU Court of Justice for the third

EU-Entschlüsselungspläne offenbar „beschlossene Sache“ by Erich Moechel for fm4.ORF.at Even without an official mandate from the Council for such a regulation, the Commission has already started to anchor a decryption requirement in other regulation projects. Chronicle of the second Cyberwars from 2014 to today, Part II. You can find part one here. The controversial resolution of the Council of Ministers against secure encryption was anchored in the new draft guidelines for “high-class cyber security” of December 16. Since resolutions are not binding per se, this indicates a “Fait Accompli”, an informally already decided matter. From data retention (until 2006) to the currently adopted regulation against online terrorist propaganda (start in 2016) , all major EU surveillance projects have started in this way. So much more than the public information available so far should have already

Translated Article: EU Directive for “High-Class Cybersecurity” with Duplicate Keys

Sanna/ December 29, 2020/ Conference, Security, Stories

EU-Richtlinie für „hochklassige Cybersicherheit“ mit Nachschlüsseln by Erich Moechel for fm4.ORF.at. The key message of the Council of Ministers’ resolution against secure encryption has already arrived in a first draft directive. For this reason here’s a historical outline of the new Crypto Wars since 2014. The resolution of the EU Council of Ministers against secure encryption, which resulted in so much criticism, has already appeared in a first draft directive. A corresponding passage can be found in the new draft directive on “Measures for high-quality cybersecurity in the Union”. The date of December 16 of the document shows that it was already drawn up before the Council resolution was passed (on December 19). Here, too, it is claimed that secure end-to-end encryption remains intact if duplicate keys are generated for third parties. Meanwhile the EU

ROOTs 2020: A survey on practical adversarial examples for malware classifiers – Daniel Park

Sanna/ November 18, 2020/ ROOTS

Machine learning based models have proven to be effective in a variety of problem spaces, especially in malware detection and classification. However, with the discovery of deep learning models’ vulnerability to adversarial perturbations, a new attack has been developed against these models. The first attacks based on adversarial example research focused on generating feature vectors, but more recent research shows it is possible to generate evasive malware samples. In this talk, I will discuss several attacks that have been developed against machine learning based malware classifiers that leverage adversarial perturbations to develop an adversarial malware example. Adversarial malware examples differ from adversarial examples in the natural image domain in that they must retain the original malicious program logic in addition to evading detection or classification. Adversarial machine learning has become increasingly popular and is

ROOTs 2020: Exploiting Interfaces of Secure Encrypted Virtual Machines – Martin Radev

Sanna/ November 18, 2020/ ROOTS

Cloud computing is a convenient model for processing data remotely. However, users must trust their cloud provider with the confidentiality and integrity of the stored and processed data. To increase the protection of virtual machines, AMD introduced SEV, a hardware feature which aims to protect code and data in a virtual machine. This allows to store and process sensitive data in cloud environments without the need to trust the cloud provider or the underlying software. However, the virtual machine still depends on the hypervisor for performing certain activities, such as the emulation of special CPU instructions, or the emulation of devices. Yet, most code that runs in virtual machines was not written with an attacker model which considers the hypervisor as malicious. In this work, we introduce a new class of attacks in which
