DeepINTEL 2022 has started – Conference on Security Intelligence

René Pfeiffer/ November 16, 2022/ Conference, DeepIntel

We often abuse the term big picture as an analogy for a better perspective on things. With security intelligence, this is true. The DeepINTEL conference covers the strategic aspects of IT security, analyses the capabilities of potential (and actual) adversaries, and helps to bridge the gap between individual experiences of security researchers and targets. DeepINTEL 2022 has started. Topic-wise advanced persistent threats, the current geopolitical situation, psychological warfare with digital means, and techniques of malicious software in attacks are the primary focus. Selected aspects will be published in articles on this blog after the conference, because the DeepINTEL is a TLP:AMBER event.

Reminder for virtual Training: Exploiting Race Conditions

René Pfeiffer/ November 15, 2022/ Security, Training

A race condition attack is one of the most dangerous and underestimated attacks on modern web applications. It’s related to concurrency and multi-threading. Because 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. Watch this free video and feel the taste of Dawid Czagan’s live online training ”Black Belt Pentesting / Bug Hunting Millionaire: Mastering Web Attacks with Full-Stack Exploitation”- Because of our hybrid configuration of DeepSec for trainings and the conference, the Mastering Web Attacks with Full-Stack Exploitation

DeepSec 2022 Talk: Industrial-Security vs. IT-Security – What Can We Learn From Each Other? – Michael Walser

Sanna/ November 11, 2022/ Conference

In the age of digitalisation, classic IT and industry are moving ever closer together. Devices are being networked and more and more smart devices are flooding the production hall. However, IT security is often disregarded in the process. Every device in the network can be compromised and requires an adapted strategy. Experience from 30 years of IT security gives the industry an orientation – but does not solve its problems. The challenges are often completely different, and the situation often requires completely different approaches. We try an approach and show experiences from the work with our customers and partners and give food for thought on what an IT security strategy for industry can look like and what both worlds can learn from each other. We asked Michael Walser a few more questions about his

DeepSec 2022 Talk: Cyber Maturity Doesn’t Just Happen. True Tales Of A Cyber Maturity Concept – Uğur Can Atasoy

Sanna/ November 10, 2022/ Conference

Having a proper(!) security posture is more challenging than ever. Implementing the bare necessities for usability and security is scalable (literally), but the reality is always full of surprises. Dozens of assets, services, tools, requirements, workforce, risks and threats. How to keep the balance between usability, security and reputation while being honest with yourself? Many enterprises suffer from “keywords” and “trends” and have to pretend to be “proactive” by implementing the “latest” trends and approaches instead of solving the problems on “bits” that need “change”. When you look at enterprise-level security incidents, you can quickly notice that they have the latest tools, technologies and services, implemented the “Zero Trust Security” model, achieved base standards and compliance requirements, and hired the experts. Literally, they are prepared for almost all possible risks and threats, but they

DeepSec 2022 Talk: Communicative Incident Response – Hauke Gierow, Paul Gärtner

Sanna/ November 10, 2022/ Conference

Crisis communication is probably the hardest part of communication to get right – and the most important. Combine this with a successful attack attempt on a company’s network that completely shatters operation and you have all the ingredients for disaster. But especially in situations like this, it is imperative to stay calm and remain in contact with the outside world. In this talk, we will relay best practices for crisis communication and how they specifically apply to IR situations. We will show the best and the worst attempts to manage a crisis – and show that situations like this can reposition a company and build trust rather than loosing it. We asked Hauke Gierow and Paul Gärtner a few more questions about their talk. Please tell us the top 5 facts about your talk.

DeepSec 2022 Keynote: Complexity killed the Cat

René Pfeiffer/ November 8, 2022/ Conference

Complex systems is not a term indicating that you have stopped to understand something. The colloquial phrase „it’s complicated“ is often used as a joke. Complex systems have their own science. Information technology has managed to make our daily life easier. Applications manage vast amount of data, communication protocols transport countless numbers of messages, systems just work, and everything is fine. The problem is that code usually grows and never shrinks. This has implication for software development and for information security. The keynote will take you on a tour through complex systems, complexity, the limits of growth, and how the consequences can be managed in a sane way. The presentation will also try to remind you to ask questions, think twice about selecting appropriate metrics, and how to apply this approach to the tools

DeepSec Press Release: Analysis IT Security – DeepSec conference offers rich education for digital defence

Sanna/ November 2, 2022/ Conference, Press

Defending one’s digital infrastructure has never been more important. The fundamental problem of many defensive structures is the lack of an overview. Penetration tests help little if you don’t know exactly how your systems are connected to the rest of the world. This year’s DeepSec security conference offers rich support and content to sustainably increase one’s own security. On board is our supporter, the company NVISO, focusing specially on companies and organisations in critical areas. Security landscape requires collaboration Modern information technology is based on complex and extensive architectures. How do you determine the state of your own security? Many companies are not familiar with the different approaches of testing methods. The term “penetration test” has already entered the minds of many, but what findings and facts are obtained during such tests is often

We have a Mastodon account – please come and follow us!

René Pfeiffer/ October 31, 2022/ Conference

The swinging moods of billionaires have hit Twitter. 230 million users have switched ownership and now follow the erratic decisions of a single person. „Mars first!”, or something. DeepSec is using Twitter as a channel to link to blog posts and to share information about ongoing events. This will not change for the moment. However, we have created a new Mastodon account to be on the safe side. The account name is already visible on our Twitter profile page. Please follow us, if you want to receive further news without interruption. DeepSec is fond of decentralised communication channels. While this means more effort to filter and selecting sources, it is true to the original character of the Internet. We also maintain our own mailing lists which cover press releases, random scuttlebutt behind the scenes,

DeepSec 2022 Talk: Fighting Fire with Fire – Detecting DNS-Tunneling with DNS – Artsiom Holub

Sanna/ October 28, 2022/ Conference

DNS tunneling used as a covert-channel method to bypass security policies has ballooned in the landscape of Ransomware attacks in recent years. This can be attributed to CobaltStrike post exploitation tools becoming modus operandi of cybercrime syndicates operating with ransomware. Most of the detections rely on packet inspection, which suffers from scalability performance when an extensive set of sockets should be monitored in real time. Aggregation-based monitoring avoids packet inspection, but has two drawbacks: silent intruders (generating small statistical variations of legitimate traffic) and quick statistical fingerprints generation (to obtain a detection tool really applicable in the field). Our approach uses statistical analysis coupled with behavioral characteristics applied directly in the DNS resolver. This presentation will cover examples of the malicious tools used by threat actors and detections designed to protect from such tools.

DeepSec 2022 Talk: Attacking Developer Environment Through Drive-by Localhost Attacks – Joseph Beeton

Sanna/ October 26, 2022/ Conference

There is a widespread belief that services that are only bound to localhost are not accessible from the outside world. Developers for convenience sake will run services they are developing configured in a less secure way compared to how they would (hopefully!) do in higher environments. By compromising websites developers use, just injecting JS into adverts served on those sites or just a phishing attack that gets the developer to open a web browser on a compromised page, it is possible to reach out via non pre-flighted http requests to those services bound to localhost, by exploiting common misconfigurations in Spring, or known vulnerabilities found by myself and others. I’ll demonstrate during the talk, it is possible to generate a RCE on the developer’s machine or other services on their private network. As developers

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

Sanna/ October 25, 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. Watch this free video and feel the taste of Dawid Czagan’s training ”Black Belt Pentesting / Bug Hunting Millionaire: Mastering Web Attacks with Full-Stack Exploitation” (DeepSec 2022; 15-16 November; https://deepsec.net/speaker.html#WSLOT564) Dawid Czagan (@dawidczagan) is an internationally recognized security researcher and trainer. He is listed among the top hackers at HackerOne. Dawid Czagan has found security vulnerabilities in Google, Yahoo, Mozilla, Microsoft, Twitter and other companies.

Reminder for your Training @DeepSec 2022: Token Hijacking via PDF File – Dawid Czagan

Sanna/ October 22, 2022/ Training

PDF files are everywhere and they can be used to hack your web application. Imagine that the attacker prepares a malicious PDF file which steals sensitive data from a user. The PDF file is uploaded to the web application, the user reads this PDF file, and finally sensitive data is exfiltrated from the user’s browser. It’s scary, isn’t it? In a free video Dawid Czagan (DeepSec instructor) will show you step by step how this attack works and how you can check if your web application is vulnerable to this attack.
