DeepSec 2018 Talk: Uncovering Vulnerabilities in Secure Coding Guidelines – Fernando Arnaboldi

Sanna/ October 3, 2018/ Conference, Security

Several government-related and private organizations provide guidance on how to improve the security of existing software as well as best practices for developing new code. These organizations include the Computer Emergency Readiness Team (CERT) Secure Coding Standards, Common Weakness Enumeration (CWE), Open Web Application Security Project (OWASP), and National Institute of Standards and Technology (NIST) Software Assurance Metrics. Fernando’s talk will expose multiple underlying exploitable vulnerabilities in the secure code that follows the recommendations from each of these organizations. Even though these guidelines were created to improve software security, they may also inject side vulnerabilities due to a lack of proper analysis. Within secure code snippets, reviewed by many and considered trustworthy by all, are issues that attackers could exploit to escape secure directories, abuse insecure hashing and encryption practices, or even expose applications

DeepSec 2018 Talk: Security as a Community Healthcare: Helping Small Non-Profit Organisations Stay Secure – Eva Blum-Dumontet

Sanna/ October 2, 2018/ Conference, Security

This talk will look at the way Privacy International has relied on its experience from working with a network of small NGOs across the Global South to shape its approach to security and develop Thornsec, an automated way to deploy, test, and audit internal and external services for an organisation. Privacy International works with a network of over twenty organisations located in Latin America, Africa, Asia and the Middle-East. Together we research and document threats and abuses to privacy from governments and corporations and advocate for better privacy protection both from a technological and a legal standpoint. Being at the forefront of the fight against surveillance means that the partners of privacy International are sometimes exposed to oppressive political regimes. They experience a wide range of threats from office burglary, physical surveillance by intelligence

DeepSec 2018 Talk: Global Deep Scans – Measuring Vulnerability Levels across Organizations, Industries, and Countries – Luca Melette & Fabian Bräunlein

Sanna/ September 25, 2018/ Conference, Internet, Security

Metrics are plentiful, but they are hard to come by when it comes to meaningful numbers. This is why we were amazed by the submission of Luca Melette and Fabian Bräunlein. Why? This is why: “We introduce global deep scans that provide insights into the security hygiene of all organizations exposed to the Internet. Our presentation discusses vulnerability levels across different groups of organizations and points out differences in the underlying maintenance processes. We find that different industries have a lot to learn from each other and provide the necessary measurements to start these dialogues.” We asked Luca and Fabian a few more questions about their talk. Please tell us the top 5 facts about your talk. 1. Come 2. Watch 3. Our 4. Talk 5. You’ll see results from a global vulnerability scan

DeepSec 2018 Talk: Injecting Security Controls into Software Applications – Katy Anton

Sanna/ September 20, 2018/ Conference, Security

“SQL Injection was first mentioned in a 1998 article in Phrack Magazine. Twenty years later, injection is still a common occurrence in software applications (No.1 in latest OWASP Top 10 2017). For the last 20 years, we have been focusing on vulnerabilities from an attacker’s point of view and SQL injection is still King. Something else must be done.”, says Katy Anton. “What if there is another way to look at software vulnerabilities? Can vulnerabilities be decomposed into security controls familiar to developers? Which security controls are an absolute must-have, and which additional security measures do you need to take into account? These are hard questions as evidenced by the numerous insecure applications we still have today. Attend this talk to explore security vulnerabilities from a different angle. As part of this talk, we

DeepSec 2018 Talk: New Attack Vectors for the Mobile Core Networks – Dr. Silke Holtmanns / Isha Singh

Sanna/ September 19, 2018/ Conference

DeepSec has a long tradition of tackling the security of mobile networks and devices alike. The first DeepSec conference featured a presentation about the A5/1 crack. Later one we offered trainings covering mobile network security and weaknesses. So we are proud to announce Isha Singh’s and Silke Holtmanns’ talk about new attack vectors. Here is a brief summary: “Roaming or being called from abroad is being something we take for granted.”, says Silke Holtmanns. “Technically it implies that large networks communicate with each other across geographical and political boundaries. Those communication and the network behind is not well known and understood by most cellular users. This network, its background, security and usage will be explained. We will highlight the attack vectors for 2G, 3G and 4G networks and give an outlook on 5G. We

DeepSec 2018 Talk: Pure In-Memory (Shell)Code Injection in Linux Userland – reenz0h

Sanna/ September 18, 2018/ Conference, Security

A lot of research has been conducted in recent years on performing code injection in the Windows operating system without touching the disk. The same cannot be said about *NIX (and Linux specifically). Imagine yourself sitting in front of a blinking cursor, using a shell on a freshly compromised Linux server, and you want to move forward without leaving any trace behind. You need to run additional tools, but you don’t want to upload anything to the machine. Or, you simply cannot run anything because the noexec option is set on mounted partitions. What options remain? This talk will show how to bypass execution restrictions and run code on the machine, using only tools available on the system. It’s a bit challenging in an everything-is-a-file OS, but doable if you think outside the box

DeepSec 2018 Talk: Without a Trace – Cybercrime, Who are the Offenders? – Edith Huber & Bettina Pospisil

Sanna/ September 14, 2018/ Conference, Security

Cybercrime is a worldwide and diverse phenomenon, which needs multidisciplinary and global prevention and intervention strategies. Regarding the situation in Austria, no evidence-based scientific analysis exists that depicts the bright field of Cybercrime. Therefore an interdisciplinary research group investigated the phenomenon cybercrime regarding the questions – Edith Huber and Bettina Prospisil will present their findings at DeepSec 2018. We asked them a few questions about their talk: Please tell us the top 5 facts about your talk. We will talk about cybercrime, offender profiling, the typical modus operandi and successful methods to apprehend offenders. How did you come up with it? Was there something like an initial spark that set your mind on creating this talk? Cybercrime is a worldwide and diverse phenomenon, which needs multidisciplinary and global prevention and intervention strategies. Regarding the situation

DeepSec 2018 Talk: Left of Boom – Brian Contos

Sanna/ September 13, 2018/ Conference, Discussion, Security

By Brian Contos, CISO of Verodin: “The idea for my presentation “Left of Boom” was based on conversations I was having with some of my co-workers at Verodin. Many people on our team are former military and some served in Iraq and Afghanistan where they engaged in anti-IED (Improvised Explosive Device) missions. During these conversations I first heard the term, Left of Boom, and the more we discussed it, the more I found similarities with cybersecurity. Left of Boom was made popular in 2007 in reference to the U.S. military combating improvised IED used by insurgents in Afghanistan and Iraq. The U.S. military spent billions of dollars developing technology and tactics to prevent and detect IEDs before detonation, with a goal of disrupting the bomb chain. This is an analog to cybersecurity as we

DeepSec 2018 Talk: Cracking HiTag2 Crypto – Weaponising Academic Attacks for Breaking and Entering – Kevin Sheldrake

Sanna/ September 6, 2018/ Conference, Security

HiTag2 is an Radio-Frequency Identification (RFID) technology operating at 125KHz. It is distinguished from many others in the same field by its use of 2-way communications for authentication and its use of encryption to protect the data transmissions – the majority of RFID technologies at 125KHz feature no authentication or encryption at all. As a result it has been widely used to provide secure building access and has also been used as the technology that implements car immobilisers. In 2012, academic researchers Roel Verdult, Flavio D. Garcia and Josep Balasch published the seminal paper, ‘Gone in 360 Seconds: Hijacking with Hitag2’ that presented three attacks on the encryption system used in HiTag2; in 2016 Garcia et al presented a further attack in ‘Lock It and Still Lose It’. They implemented their attacks on the Proxmark 3 device

DeepSec 2018 Talk: Defense Informs Offense Improves Defense – How to Compromise an ICS Network and How to Defend It – Joe Slowik

Sanna/ September 5, 2018/ Conference, Security

Industrial control system (ICS) attacks have an aura of sophistication, high barriers to entry, and significant investment in time and resources. Yet when looking at the situation – especially recent attacks – from a defender’s perspective, nothing could be further from the truth. Initial attack, lateral movement, and entrenchment within an ICS network requires – and probably operates best – via variations of ‘pen tester 101’ actions combined with some knowledge of the environment and living off the land. Only after initial access is achieved and final targets are identified do adversaries need to enhance their knowledge of ICS-specific environments to deliver disruptive (or destructive) impacts resulting in a potentially large pool of adversaries capable of conducting operations. Examining concrete ICS attack examples allows us to explore just what is needed to breach and

DeepSec 2018 Talk: Can not See the Wood for the Trees – Too Many Security Standards for Automation Industry – Frank Ackermann

Sanna/ September 4, 2018/ Conference, Discussion, Security

“Plant operators and manufacturers are currently faced with many challenges in the field of automation.”, says Frank Ackermann. “Issues such as digitization, Industry 4.0, legal requirements or complex business processes that connect IT and OT are paramount. Related security problems and risks need to be addressed promptly and lastingly. Existing and newly created industry security standards (such as 62443, 61508 and 61511, 27001, …) are designed to help to improve security. But do the different approaches of these standards fit together? Are managers of the companies and manufacturers supported or rather confused by them? The presentation provides an overview of the key security industry standards, discusses the dependency and coverage of the standards, and aims to encourage discussion about if the standards optimize general security in industrial control systems.” We asked Frank a few

DeepSec 2018 Talk: Who Watches the Watcher? Detecting Hypervisor Introspection from Unprivileged Guests – Tomasz Tuzel

Sanna/ September 3, 2018/ Conference, Development, Security

Over the last decade we have seen a rapid rise in virtualization-based tools in which a hypervisor is used to gain insight into the runtime execution of a system. With these advances in introspection techniques, it is no longer a question of whether a hypervisor can be used to peek inside or even manipulate the VMs it executes. Thus, how can we trust that a hypervisor deployed by a cloud provider will respect the privacy of their customers? While there are hardware-based protection mechanisms with the goal of guaranteeing data privacy even in the presence of such an “introspecting” hypervisor, there are currently no tools that can check whether the hypervisor is introspecting when it shouldn’t. We have developed a software package that analyzes instructions and memory accesses on an unprivileged guest system which

DeepSec 2018 Talk: Open Source Network Monitoring – Paula de la Hoz Garrido

Sanna/ August 31, 2018/ Conference, Security

“I’d like to offer an introduction into Network System Monitoring using different open tools available in Linux.”, says Paula. “The talk is a technical approach to identify the best sniffing points in a network and how to orchestrate a full analysis of the content to secure the network, as well as showing ideas of collaborative and distributed hacking. Also, for a better performance, the talk includes a brief guide into configuring a Raspberry Pi for creating a simple Network Capture Probe. The main point of the talk is to show how open source tools are a nice option for this kind of security assessment.” We asked Paula a few more questions about her topic of expertise: Please tell us the top 5 facts about your talk.

DeepSec 2018 Talk: Building your Own WAF as a Service and Forgetting about False Positives – Juan Berner

Sanna/ August 30, 2018/ Conference, Internet, Security

When a Web Application Firewall (WAF) is presented as a defensive solution to web application attacks, there is usually a decision to be made: Will this be placed inline (and risk affecting users due to outages or latency) or will it be placed out of band (not affecting users but not protecting them either). In his talk Juan Berner will cover a different approach you can take when deciding how to use any WAF at your disposal, which is to try and get the best of both worlds, making the WAF work in passive mode out of band detecting attacks and in active mode by selectively routing traffic through your WAF to decide if it should block the request or allow it. To achieve this you will have to abstract the WAF around a
