DeepSec 2021 Presentation: Don’t get Hacked, get AMiner! Smart Log Data Analytics for Incident Detection – Florian Skopik, Markus Wurzenberger, Max Landauer

Sanna/ September 13, 2021/ Conference, Security/ 0 comments

“Prevention is ideal, but detection is a must”. Active monitoring and intrusion detection systems (IDS) are the backbone of every effective cyber security framework. Whenever carefully planned, implemented and executed preventive security measures fail, IDS are a vital part of the last line of defence. IDS are an essential measure to detect the first steps of an attempted intrusion in a timely manner. This is a prerequisite to avoid further harm. It is commonly agreed that active monitoring of networks and systems and the application of IDS are a vital part of the state of the art. Usually, findings of IDS, as well as major events from monitoring, are forwarded to, managed and analyzed with SIEM solutions. These security information and event management solutions provide a detailed view on the status of an infrastructure

Translated Article: New ETSI Standard for Reporting Security Vulnerabilities

Sanna/ September 9, 2021/ Stories/ 0 comments

Neuer ETSI-Standard zur Meldung von Sicherheitslücken by Erich Moechel for fm4.ORF.at The European Standards Institute for Telecommunications ETSI, previously known more for the standardization of back doors for surveillance authorities than for IT security, is now concerned with finding non-standardized security vulnerabilities. Late but still, the discovery of ever new, critical security gaps in IT equipment in industry has finally woken up the European Standards Institute for Telecommunications (ETSI). The public review period for an ETSI specification, which is intended to standardize the reporting process of security vulnerabilities by third parties, runs until September 15. Since the introduction of LTE (4G), the standards of the IT world have increasingly applied to the formerly proprietary networks of the telecoms. This specification takes this into account by standardizing important IT security processes for the world of telecommunications. However,

DeepSec 2021 Talk: Web Cache Tunneling – Justin Ohneiser

Sanna/ August 31, 2021/ Conference/ 0 comments

By using cache poisoning to store arbitrary data, we can use public web caches as open ephemeral storage to facilitate anonymous and evasive communication between network clients. We asked Justin a few more questions about his talk. Please tell us the top facts about your talk. Public web caches, when improperly configured, can be used as open ephemeral storage. Combined with a synchronization technique, this ephemeral storage can be used to tunnel arbitrary data between network clients. Tunneling data in this manner requires no listening service, as all endpoints behave as clients to the web cache server, allowing trivial use of anonymizing protocols. The conditions for this technique are present on several extremely popular websites, and the use of this technique by malware could make network detection nearly impossible. How did you come up

DeepSec 2021 Talk: Those Among Us – The Insider Threat facing Organizations – Robert Sell

Sanna/ August 27, 2021/ Conference/ 0 comments

Organizations spend a considerable amount of time and money protecting themselves from external threats while practically ignoring the significant threats from within. Cybercrime has an estimated cost of $2 trillion in 2019 with an average cost per data breach of $3.9 million. This global cost is expected to grow to $6 trillion annually by 2021.  In 2018, 34% of those data breaches involved internal factors and this trend continues to grow. This hard on the outside but soft in the middle approach by Information Security departments leaves organizations susceptible to a variety of insider threats that could be avoided. In this talk, I will present the extent of the issue, the types of insider threats to expect and how organizations can mitigate these risks. We asked Robert a few more questions about his talk.

DeepSec 2021 Talk: Hunting for LoLs (a ML Living of the Land Classifier) – Tiberiu Boros, Andrei Cotaie

Sanna/ August 25, 2021/ Conference/ 0 comments

Living of the Land is not a brand-new concept. The knowledge and resources have been out there for several years now. Still, LoL is one of the preferred approaches when we are speaking about highly skilled attackers or security professionals. There are two main reasons for this: Experts tend not to reinvent the wheel Attackers like to keep a low profile/footprint (no random binaries/scripts on the disk) This talk focuses on detecting attacker activity/Living of the Land commands using Machine Learning, for both Linux and Windows systems. Most of the AV vendors do not treat the command itself (from a syntax and vocabulary perspective) as an attack vector. And most of the log-based alerts are static, have a limited specter and are hard to update. Furthermore, classic LoL detection mechanisms are noisy and somewhat

DeepSec 2021 Training: How to Break and Secure Single Sign-On (OAuth and OpenID Connect) – Karsten Meyer zu Selhausen

Sanna/ August 23, 2021/ Training/ 0 comments

Implementing single sign-on has huge benefits in general. It allows to design the registration and login process for users to be as simple as possible, and enables applications to be connected to social networks. Although OAuth and OpenID Connect are established as today’s common standards, serious attacks on them have been discovered within recent years. These attacks exploit the complexity of the underlying standards and implementation flaws, and allow attackers to authenticate themselves as arbitrary users or to access confidential user data. By doing so, attackers can potentially read, manipulate, or delete data of arbitrary users across these applications. Due to the critical role that single sign-on fulfills in applications nowadays, it is important to understand and address pitfalls when using OAuth and OpenID Connect. However, automatic security scanners are not able to properly

Scuttlebutt – Summer in the city, reviews, and more security content

René Pfeiffer/ August 22, 2021/ Scuttlebutt/ 0 comments

Dear readers, gossip has been a bit rare in the past weeks. This was because of the intense summer heat here in Vienna. The opposite of the chill factor made working in the hot city extremely difficult. Additionally, we tackled dealing with backend archaeology. A part of our internal application for managing the call for papers, the reviews, and the schedule celebrates its 10th birthday. I like code that runs smoothly despite platform updates, but now is the time for some changes. And no, we do not expose the code to the Internet. You can stop looking for it. 😉 We just finished the major part of reviews of the submissions. It always takes a while, given that we start with the final review in August. Contacting people during Summer adds extra round trip

Thanks for your submission! We are working on final reviews.

René Pfeiffer/ August 2, 2021/ Conference/ 0 comments

In the past months we kept blogging about various issues in information security and news regarding our event in November. The Summer months are hard on the process of following news with articles. A lot of things happen, and software still has security-relevant bugs. It’s just that fewer people (than usual) care. We care, and therefore we will complete the reviews of your submissions. The preliminary schedule will be published soon. Thanks for taking your time! We appreciate your contributions. You have made the reviews very hard, as every year. 😉 If you still have some ideas, feel free to submit them!

DeepSec 2021 Press Release: Surveillance as Organized Crime – DeepSec Conference Criticizes Pegasus Spy Software as a legal Vacuum

Sanna/ July 30, 2021/ Conference, DeepIntel, Press/ 0 comments

The information published by the Pegasus Project consortium on the systematic abuse of this monitoring software for smartphones clearly shows that rampant surveillance can hardly be distinguished from organized crime. Security experts are increasingly warning against the hoarding of unknown security vulnerabilities by companies that develop espionage products. Information security for society, authorities and the economy are incompatible with the existence of such tools. In addition, they represent a threat to the national security of every country. We can only maintain a real locational advantage for Europe through consistent IT security. Battle for Communication Content Since the first discussions about the availability of strong encryption for private individuals and companies, the security of digital communication has been hotly contested. In the 1990s, the US government wanted to enshrine access to messages and calls from
