DeepSec 2016 Talk: Obfuscated Financial Fraud Android Malware: Detection And Behavior Tracking – Inseung Yang

In Korea in particular, hackers have distributed sophisticated and complex financial fraud android malware through various means of distribution, such as SMS phishing, Google play, compromised web servers and home routers (IoT). In some cases, both smartphone and PC users are targeted simultaneously.

Inseung Yang and his team collect mobile android malware via an automated analysis system, detect obfuscations and malicious packer apps. In his presentation Inseung Yang will describe trends of malicious android apps and obfuscated mobile malware in Korea. He’ll explain the policy methods for Korean mobile banking and the attack methods used by hackers, f.ex. the stealing of certifications, fake banking apps that require the  security numbers issued to users when they open their accounts, Automatic Response Service(ARS) phishing attacks in conjunction with Call Forwarding, and the requesting of the One Time Password(OTP) number.

But Inseung will not only talk about recent trends of obfuscated malicious android apps in Korea, he’ll also explain various mobile protection techniques to prevent you from obfuscation, packing and anti-debugging and other methods used to obstruct the detection and analysis of malware.

DeepSec 2016 Keynote: Security in my Rear-View Mirror – Marcus J. Ranum

Everything that’s old is new again, and if you work in security long enough, you’ll see the same ideas re-invented and marketed as the new new thing. Or, you see solutions in search of a problem, dusted off and re-marketed in a new niche.

At this year’s DeepSec conference the keynote will be given by Marcus Ranum, who set up the first email server for whitehouse.gov. He will reflect upon over 30 years of IT security and make a few wild guesses for where this all may wind up. Spoiler alert: Security will not be a “solved” problem.

Marcus answered a few questions beforehand:

Please tell us the Top 5 facts about your talk.

  • I’ll be talking about how the security market evolves from here.
  • I’ll be talking about the relationship between security and management
  • It’s going to be depressing.
  • I have been working in security since the mid/late 1980s and I don’t think we have made any progress at all
  • I don’t think we will make much progress in the near-term future, either.

Is there something you want everyone to know?

It’s all about management cost.

DeepSec 2016 Talk: Systematic Fuzzing and Testing of TLS Libraries – Juraj Somorovsky

In his talk Juraj Somorovsky presents TLS-Attacker, a novel framework for evaluating the security of TLS libraries. Using a simple interface, TLS-Attacker allows security engineers to create custom TLS message flows and arbitrarily modify TLS message contents in order to test the behavior of their TLS libraries. Based on TLS-Attacker, he and his team first developed a two-stage TLS fuzzing approach. This approach automatically searches for cryptographic failures and boundary violation vulnerabilities. It allowed him to find unusual padding oracle vulnerabilities and overflows/overreads in widely used TLS libraries, including OpenSSL, Botan, and MatrixSSL.

Juraj’s findings encouraged the use of comprehensive test suites for the evaluation of TLS libraries, including positive as well as negative tests. He and his team used TLS-Attacker to create such a test suite framework, which finds further problems in TLS libraries.

TLS-Attacker is an open source tool, and is currently being deployed for internal tests in Botan and MatrixSSL. We asked Juraj Somorovsky some questions about his matter of interest.

Please tell us the top 5 facts about your talk.

  • It gives an overview of the recent attacks on TLS (Transport Layer Security).
  • It presents an open source framework for the evaluation of TLS libraries, which can be used by security researchers or developers: TLS-Attacker.
  • It shows how to use TLS-Attacker to test and fuzz TLS libraries, or how to create custom proof-of-concept attacks.
  • It presents vulnerabilities found with TLS-Attacker, including padding oracles in OpenSSL, Botan and MatrixSSL.
  • It shows a video from South Park.

How did you come up with it? Was there something like an initial spark that set your mind on creating this talk?

In the recent years we could observe many vulnerabilities in important TLS implementations. We saw attacks targeting improper encryption algorithms and configurations, complex state machine attacks, or buffer overflows and overreads. This motivated us to create a tool that allows security researchers to easily implement proof-of-concept attacks, or execute fuzzing and find such attacks automatically.

Why do you think this is an important topic?

TLS is arguably the most important cryptographic protocol. We use it every day in our browser to login on our favourite web sites or to execute secure payments. Its security evaluation is therefore of a huge importance.

Is there something you want everybody to know – some good advice for our readers maybe?

This talk is for everybody who is interested in TLS and secure crypto protocols. As a security researcher or pentester you will learn how to execute specific attacks like padding oracles. As a security developer you will learn how to evaluate the security of your TLS servers.

A prediction about the future – what do you think will be the next innovations or future downfalls when it comes to particularly your field of expertise / the topic of your talk?

The new TLS 1.3 standard is being developed. This standard will be integrated into new TLS libraries, including further novel TLS features and extensions. These new implementations will lead to novel security bugs and problems. We hope that with a careful systematic TLS fuzzing and testing new security problems can be eliminated.

DeepSec2016 Talk: Smart Sheriff, Dumb Idea: The Wild West of Government Assisted Parenting – Abraham Aranguren & Fabian Fäßler

Would you want to let your kids discover the darker corners of the Internet without protection? Wouldn’t it be handy to know what they do online, to be alerted when they search for dangerous keywords and to be able to control what websites they can visit and even when they play games?

Worry no longer, the South Korean government got you covered. Simply install the “Smart Sheriff” app on your and your kids’ phones. Smart Sheriff is the first parental-control mobile app that has been made a legally required, obligatory install in an entire country! Yay, monitoring!

Well, something shady yet mandatory like this cannot come about without an external pentest. And even better, one that wasn’t solicited by the maintainer but initiated by the OTF and CitizenLab and executed by the Cure53 team! In this talk, two of the Cure53 testers involved in the first and, who would have guessed, second penetration test against the “Smart Sheriff” app, will share their findings. Maybe everything went allright, maybe the million kids forced to have this app run on their devices are safe. Maybe. But if so would there be a talk about it?

We all know, mandated surveillance apps to protect children are a great idea, and outsourcing to the lowest bidder, always delivers the best results. Right?

Going over the first and second pentest results we will share our impressions about the “security” of this ecosystem and show examples about the “comprehensive” vendor response, addressing “all” the findings impeccably. This talk is a great example of how security research concerning a serious political decision and mandatory measures might achieve nothing at all – or of how a simple pentest together with excellent activist work may spark a political discussion and more.

DeepSec 2016: Social Engineering remains the most dangerous Threat to Companies – DeepSec offers a Workshop on the Defence of social Manipulation as part of IT

If you follow the news on information security, you see superlative after superlative. Millions of passwords were stolen. Hundreds of thousands of cameras suddenly became tools for blackmail. Countless data got copied unauthorized. Often, after a few paragraphs, your read about technical solutions that should put a stop to these burglaries. Therefore one forgets that nowadays hermetically locked doors can be easily opened just by a telephone call or an e-mail message. According to a publication of the British Federation of Small Businesses, almost 50% of attacks are social engineering attacks, which means attacks through social manipulation.Thus, investments in technical defense measures remain completely ineffective.

Mere security awareness does not help anymore

In the past approaches to defend against attacks on the weak spot human being have focused on awareness trainings. But in our modern business world awareness is not enough. The knowledge of the dangers of social engineering aka social manipulation is already available. Countermeasures must now become much more concrete. Employees must be able to understand, recognize and independently avert the methods of their adversaries. This competency can not be achieved only through security awareness. Let’s use the analogy of fire-fighting to underline this point:

The knowledge about a possible fire in the workplace is of little help if nobody is able or allowed to use a fire extinguisher in the event of a crisis. All classic trainings focusing on the defense against social engineering only deal with the topic up to a certain point. Unfortunately, what has to be done after the fire spot has been discovered is often no matter of discussion. But exactly at this point, training has to become tangible, otherwise it does not contribute to the protection of a company.

Social engineering, the poor relation of information security

The serious implications of attacks against the psyche of employees are strongly underestimated. While technical solutions, due to their inscrutable complexity, seem to be highly effective, the studies of habits, communication styles, absences, internal company celebrations, daily lunches or after-work activities seem almost banal. But each piece of seemingly banal information is a building block in the attacker’s plan. This is easier said than done, but you must build counter-measures as a complete campaign. Many companies have guidelines for dealing with strangers and sensitive information. Their IT departments are also inaugurated.

But one has to connect the individual parts to form a network to protect the weak points of human communication in office life, otherwise the best fire protection system will not suffice. Do not consider your personnel as a potential risk, but as an vital part of your security architecture. Everyone can fall victim to social engineering attacks; there is no shame in that. It is therefore crucial to offer ways to your employees to report weaknesses anonymously. If all shall pull together, the threshold for co-operation must be as low as possible, especially when it comes to security.

Hands-on workshop with practical exercises, based on examples from the real world

One of the focus points of the 10th DeepSec In-Depth Security Conference will be social engineering and how to defend yourself against it. The conference program includes not only lectures on the subject but also a training conducted by two experts in this field. In a two-day workshop, Cyni Winegard and Bethany Ward will present real-world scenarios and enact them with their participants. The course aims not only to create awareness, but to use practical examples and role playing for participants to gain experiences that can be incorporated into their own habits. All examples will be tailored to the abilities of the participants – and to the weaknesses of their professional environment.

When it comes to defense, it has to acknowledge and withstand the ability of your opponents. The workshops Penetration Testing Humans helps to create a real defense of the human psyche. The trainers bring their experiences from many years of safety tests and confront the participants with real dialogues and actions from successful attacks.

IT-SeCX 2016: Talk about Relationship between Software Development and IT Security

The IT-SeCX 2016 event takes place on 4 November at the St. Pölten University of Applied Sciences LLC. It’s a night of security talks, held by various speakers from the industry, academic world, and other institutions. We will give a presentation exploring the relationship between the fine art of software development and the dark art of information security. We all know about bugs, glitches, error conditions, and flat failures of software design. There are links between the development cycle and the work of information security experts (or sysadmins who always have to deal with things that break). If you deal with any of these professions mentioned, you should drop by and attend the talk.

DeepSec2016 Talk: Of Mice and Keyboards: On the Security of Modern Wireless Desktop Sets – Gerhard Klostermeier

Wireless desktop sets have become more popular and more widespread in the last couple of years. From an attacker’s perspective, these radio-based devices represent an attractive target both allowing to take control of a computer system and to gain knowledge of sensitive data like passwords. Wireless transmissions offer attackers a big advantage: you don’t have to be around to attack something or someone. Plus the victims often don’t know what it happening.

At DeepSec 2016 Gerhard Klostermeier will present the results of research on the matter of wireless mouse/keyboard attacks. Furthermore you he will demonstrate ways in which modern wireless desktop sets of several manufacturers can be attacked by practically exploiting different security vulnerabilities.

We recommend this talk to anyone still using old-fashioned input devices for creating content.

DeepSec 2016 Talk: Assessing the Hacking Capabilities of Institutional and Non-institutional Players – Stefan Schumacher

Cyberwar, Cyberterror and Cybercrime have been buzzwords for several years now. Given the correct context, using cyber has merits. However Cyber-Headlines are full with Cyber-Reports about Cyber-Incidents, Cyber-Hacking and Cyber-Cyber in general. However, that whole discussion does not only suffer from sensationalism of journalists and bloggers, there are also some fundamental problems, says Stefan Schumacher. We are still lacking useful definitions for modern IT security threats and we still have to think about the assessment of capabilities in the IT field.Besides institutional actors like states and their military and intelligence community we also have to assess the capabilities of non-institutional actors like terrorist groups or organised crime.

Unlike the assessment of classic military strength (eg. fighting power or Kriegsstärkenachweise), assessing the capabilities and powers of actors in the IT field is much more complicated and complex.In his talk Stefan will introduce the first tools, methods and statistics to compare hacking capabilites and assess the »cyber fighting power« of different actors. He will look into the capabilities of state actors and their agencies as well as the capabilities of their economies and how well they can be translated into IT security.

Additionally, Stefan Schumacher will try to assess the capabilities of independent groups like organised cyber crime, terrorists and hacking groups. Their capabilities are much harder to assess, so he will look also into their history, culture and ethics to find answers. Finally, Stefan will introduce some tools from IO psychology that can be used to assess the technical capabilities of organisations and the motives and motivations of their members.

stefan-schumacherStefan Schumacher is the president of the Magdeburg Institute for Security Research and editor of the Magdeburg Journal for Security Research in Magdeburg/Germany. He started his hacking career before the fall of the Berlin Wall, on a small East German computer with 1.75 MHz and a Datasette drive.
Ever since he liked to explore technical and social systems, with a focus on security and how to exploit them. He was a NetBSD developer for some years and  involved in several other Open Source projects and events. He studied Educational Science and Psychology, has done a lot of unique research about the Psychology of Security with a focus on Social Engineering, User Training and Didactics of Security/Cryptography. Currently he’s leading the research project Psychology of Security,focusing on fundamental qualitative and quantitative research about the perception and construction of security. He presents the results of his research regularly at international conferences like AusCert Australia, Chaos Communication Congress, Chaos Communciation Camp, DeepSec Vienna, DeepIntel Salzburg, Positive Hack Days Moscow or LinuxDays Luxembourg and in security related journals and books.

DeepSec 2016 Talk: Why Companies Must Control Their Data in the Era of IoT – and How To – Kurt Kammerer

In his talk Kurt Kammerer addresses any company’s dilemma: The need for data sharing in the era of IoT while at the same time controlling access and ownership. In order to succeed in business, it is imperative to make data available to customers, suppliers and business partners. However, the explosion and the proclaimed free flow of data can turn against an organisation and threaten its very existence, if not professionally controlled. We asked Mr. Kammerer a few questions beforehand.

Please tell us the top 5 facts about your talk.

  1. The relevance of “data” increases by the day and “data” is imperative to compete. Therefore, it is an asset companies must control.
  2. Data ownership is increasingly being challenged in the era of cloud/IoT (who created the data and who actually owns it?)
  3. Not exercising enough control over your data will dilute your business model.
  4. Data privacy and data ownership are cornerstones for any IoT use case
  5. IoT will control you (rather than the other way round) unless you take data governance, ownership and control seriously.

How did you come up with it? Was there something like an initial spark that set your mind on creating this talk?

My talk addresses the major “data dilemma” that enterprises have to face:

  • On the one hand, data has emerged as the strongest competitive asset that a company has. Limiting access to such data is vital for the survival of any company.
  • On the other hand, only if you share and publish data within your commercial ecosystem, you can have commercial success.

Reconciling these contradictory requirements in daily business life requires full dedication, skill and discipline from all stakeholders of an organisation or ecosystem. At the same time, consumers must be aware of this in order to make informed decisions about with whom they want to share which data.

Why do you think this is an important topic?

In the era of IoT, data is king!

Is there something you want everybody to know – some good advice for our readers maybe?

Whoever is in control of your data, will be able to control your destiny.

A prediction about the future – What do you think will be the next innovations or future downfalls when it comes to particularly your field of expertise / the topic of your talk?

Being in control means being in control of your critical data, and not all data available. We will see gigantic “big data” initiatives fail due to the daunting and cumbersome task to identify “the needles in the haystack” if the haystack experiences explosive growth. In contrast, we will see “smart data” solutions succeed that do not bet on sheer processing power, but also take relevance into account. Therefore, keeping your “haystack” at a size that fits your barn by filtering out the noise will remain critically important.

DeepSec 2016 Talk: Insider Threat: Profiling, Intent and Motivations of White Collar Offenders – Ulrike Hugl

Malicious insider threat is not only a security- or technical-oriented issue, mainly it’s a behavioural one, says Prof. Ulrike Hugl. Insiders are so-called ‘trusted’ or privileged employees, very often with legitimate access to the organization’s systems, and they are hard to catch. Furthermore, it is difficult to find appropriate predictive factors and prevention and detection measures.

In fact, based on new technical developments and opportunities, data theft has become much easier these days: Mobile trends like BYOD, the increased ability to work from home, access to the organization’s systems when on the road, cloud services with related security vulnerabilities for example, as well as more and more malware opportunities have increased the potential of related attacks. Other main security obstacles and trigger factors inside and outside an organization may be, to name a few, a companies poor market performance and fear of job loss, internal (security-related) budget constraints, the complexity of the internal (IT) environment, competing priorities, a lack of top-level direction and leadership, as well as a lack of awareness training, … the list goes on and on.
Anyway, current studies in the field show that malicious insider threat is an increasing crucial issue for companies and governmental institutions. Beside the mentioned dependence on ICT, new attack forms and collaborations with third parties (for example social engineers and/or hackers) are on the rise.

In her talk Professor Hugl will focus on the current state of insider threat,on motivational and behavioural aspects as well as on current profiles of malicious insiders based on the newest available data. The emphasis on characteristics of malicious insiders is crucial, but one should also be aware of the fact that in many cases of attacks boundaries between insiders and outsiders are blurred. Her talk will close with some starting points for organizational insider threat prevention management. We asked Prof.  Hugl some questions beforehand.

Please tell us the top 5 facts about your talk.

  • Insider threat seems to be a hidden risk within organizations.
  • Nevertheless, current studies show that companies estimate they are at risk.
  • When it comes to Insider threat various motivational issues and (sometimes) also neutralization strategies play a crucial role on the personal level; on the organizational level we have to consider opportunity factors, the ‘tone at the top’ and its misuse, which negativly supports sub cultures.
  • New technological developments are triggering organizational vulnerabilities 
  • And: Boundaries of insiders and outsiders are becoming blurred in many cases of current attacks.

 How did you come up with it? Was there something like an initial spark that set your mind on creating this talk?

An initial point was my work at the University of St. Gallen. There, I think it was about in 2002, first initiatives in the field of Internet of Things(IoT)-applications and related IoT-research labs came up. At that early state of research, in my impression, the focus of thoughts was mainly on the technological side and what’s achievable in developing new business models with sustainable profit. To me IoT was more than impressing, but also triggering many open questions: What does IoT mean for business, for individuals, for society? How will it change our world? My impression was that most researchers did not really think about aspects like privacy-by-design for consumers/users or even information security-related aspects for organizations. For me this was the starting point for research in the field of new or (potentially) upcoming technologies, related aspects of data protection and (potential) impacts on the whole field of organizational information security.

Why insider threat? First, it’s related to organizational information security. Second, it’s a very interesting topic because diverse fields are involved: from technology, personnel management (like trainings, leadership, and behavior of peers), the organizational structure (f.ex. internal whistleblowing systems, counterespionage departments, coordination and control), the external environment of an organization (market development, etc.), to interesting theories and research results from criminology and others disciplines. All in all, and that’s a big point, a human’s behavior is hard to predict. Humans do have their characteristics, their personal environment and their own specific situation inside the organization – and such issues can play a triggering role in conducting misuse.
To summarize, insider threat is – depending on your point of view and the topic you are looking on – blurring the boundaries between various scientific disciplines. Therefore, for me, dealing with this topic is fascinating!

 Why do you think this is an important topic?

As just mentioned, to protect an organization’s intellectual property and crucial assets, diverse factors have to be considered: personal, organizational, and behavioral factors or indicators to find useful starting points for the prevention and detection of malicious acting of so-called ‘trusted employees’. Current studies show a clear tendency: Insider threat continues to pose the most crucial threat to organizations everywhere. In 2015, more than the half or even up to 60 percent of all attacks were carried out by malicious insiders. And, as many cases show, such offenders may cause substantial reputational or financial losses.

 Is there something you want everybody to know – Some good advice for our readers maybe?

It’s hard to think of your staff as a potential ‘threat’. Nevertheless, we have to learn that not all our employees have only good intentions. These days we know about diverse starting points, which enable us more and more to ‘walk in an offender’s shoes’. Furthermore, we know about various individual motivational factors as well as organizational and environmental triggers for fraud and misconduct.

I am looking forward to give you an impression of the current state of research and threat potential in the field, but also perhaps some new thoughts and ideas to implement some measures inside your organization.

A prediction about the future – what do you think will be the next innovations or future downfalls when it comes to particularly your field of expertise / the topic of your talk?

From the organizational point of view, in the field of insider threat, the crucial challenge is to find a balance between trust and suspicion when building up related counter-measures. This is sometimes hard and seems like ‘crying for the moon’. But, we all know things are in progress and will further develop.

Another last aspect: Some research is done in all mentioned scientific fields, but more effort is needed to deal with it in a more systematic way and we need much more researchers dealing with this topic. In economic and social sciences, the topic is not really known and far from ‘mainstream’. Within these disciplines traditional research is currently mainly still focused on established and traditional fields of expertise, often with a narrow research focus. However, insider threat and related issues like economic crime and industrial espionage should also be taken into account and being established inside traditional research institutions. They should be treated as very relevant issues for further theoretical innovation and specific managerial implications.

Her research mainly focuses on new technologies and their impact on information security and data protection of organizations, as well as on occupational/corporate crime (especially insider threat) and industrial espionage issues.

DeepSec2016 Workshop: IoT Hacking: Linux Embedded, Bluetooth Smart, KNX Home Automation – Slawomir Jasek

“The ongoing rise of the machines leaves no doubt – we have to face them”, says Slawomir Jasek, and adds: “It is hard not to agree with one of the greatest military strategists Sun Tzu: “If you know your enemies and know yourself, you will not be put at risk even in a hundred battles”. Right now it is about time to fill that gap in your skills by confronting the devices, learning their flaws, catalog ways to defeat them, and – above all – develop means to reduce the risk and regain control.” Slawomir’s training consists of several modules:

1. Linux embedded
Linux embedded is probably the most popular OS, especially in SOHO equipment like routers, cameras, smart plugs, alarms, bulbs, home automation, and even wireless rifles. Based on several examples, you will learn about the most common flaws (auth bypass, command injection, path traversal, backdoor services…). We will open a wireless doorlock remotely, hack cameras and take control over other devices. You will also interact with representative specimens which took part in recent DDoS events.

2. Bluetooth Low Energy
One of the most sought after IoT technologies. Learn how it works, about risks and possible attacks. Using among others new BLE MITM proxy tool developed by the author, we will hack various devices: 5 different smart locks, mobile Point of Sale, authentication token, beacons, anti-thief protection and others.

3. KNX home automation
Learn how to take control over the most common home automation system: EIB/KNX.
Following the introduction on the system basics, we will hack the provided demo installation, abusing common misconfiguration weaknesses – in a similar way a luxury hotel in China was hacked a few years back.

Do you want to know more? We asked Slawomir a few more questions about his workshop.

Please tell us the top 5 facts about your talk.

  • The training consists of several unique cutting-edge topics.
  • Focused on practical exercises we will hack multiple real devices.
  • All participants will receive a Raspberry Pi and 2 BT4 dongles – A beginner’s hardware lab for BLE.
  • It will be possible to further practice BLE hacking at home, with a specially designed Bluetooth Smart HackmeLock, a vulnerable hardware lock,  software- simulated, consisting of a mobile application.
  • Regardless if you are a beginner or a skilled pentester, you will learn something new and have a good time.

How did you come up with it? Was there something like an initial spark that set your mind on creating this Workshop?

I was always interested in taking control over surrounding devices. I got my Msc degree in Automatics and Robotics, and for a while I designed secure Linux embedded appliances for national agencies. That is why current vendors’ irresponsibility and insecurity level of most routers, cameras, home automation etc. constantly boggles me. I understand the market demands features produced at low cost, but I believe it is possible to integrate security into the development process. The world won’t change with a snap of one’s fingers, for now we will have to deal with what we have. So I decided to share my collection of hillariously vulnerable devices – the ease of exploitation should be an eye-opener – along with a few -not always straightforward – hacks on how to patch them on your own.

The “initial spark” that led me to more comprehensive Bluetooth Smart research was a local “hacking competition”: the goal was to steal a car protected by an BLE unlocking device. I pointed out several vulnerabilities in the mechanism, which allow you to take full control over it. For that I designed novel attack scenarios and tools, which I presented this year at BlackHat USA (more details: www.gattack.io).

And KNX home automation – I created my own super-smart home installation. Well, in the beginning it was far from perfect, especially for my non-smartphone wife, who could not switch the light on without my help. But I got to know the systems inside-out (including its Achilles’ heel), and recently also organized an online KNX hacking challenge.

Why do you think this is an important topic?

I think a quick scroll through the recent headlines will do as an sufficient answer. Of course the media often overestimate the real risk, but you just can’t ignore the fact anymore that the devices are increasingly surrounding us and are often used as a weapon against us.

Is there something you want everybody to know – some good advice for our readers maybe?

Did I mention the free Raspberry and other goodies already?

A prediction about the future – What do you think will be the next innovations or future downfalls when it comes to particularly your field of expertise / the topic of your workshop?

They rapidly grow in numbers, processing power and network bandwidth. Machines control more and more of our life. No doubt, they will strike again. Next time you better be ready.

DeepSec2016 Talk: Abusing LUKS to Hack the System – Interview with Ismael Ripoll & Hector Marco

Please tell us the top facts about your talk.

  • It discloses a vulnerability that affects Linux systems encrypted with Luks, and how it can be abused to escalate privileges: CVE-2016-4484
  • Includes a sketch of the boot sequence with a deeper insight into the initrd Linux process
  • A brief discussion about why complexity is the enemy of security: The whole system needs to be observed.
  • A practical real working demo attack will be presented.

How did you come up with it? Was there something like an initial spark that set your mind on creating this talk?

Well, this is a difficult question. Basically, it is an attitude in front of the computer. When we start a research line, we don’t stop digging until the ultimate doubt and question is addressed. After the GRUB 28 bug, we keep reviewing the rest of the Linux boot sequence.

Why do you think this is an important topic?

Although we will present how to abuse the system thought a cryptography service, the root of the problem is the “complexity”: The idea of complexity is not limited to difficult mathematical algorithms or advanced data structures, but also the combination of subsystems increases the overall complexity. The vulnerability that will be presented is a good example of how the addition of new features (in this case, security features) may weaken the system by creating new faults.

Is there something you want everybody to know – some good advice for our readers maybe?

Our talk will show that it is not necessary to use complex exploits or advanced USB hacking devices to hack the system. Knowledge is the only necessary tool. Do you remember the GRUB 28 bug? This time it is a little bit more complex but the result is… surprising.

A prediction for the future – What, do you think, will be the next innovations or future downfalls when it comes to particularly your field of expertise / the topic of your talk?

Thanks to the advances in mitigation techniques (ASLR, NX, SSP, CFI,etc..) and better software engineering methods, the number of exploitable faults may be reduced (as far as the programmers for the IoT do apply those technologies). A more dangerous type of vulnerabilities are those caused by the interaction of two or more systems which work correct when used separately.

On the other hand, cryptography will always be a hot topic. As far as crypto algorithms become outdated by the advances in computer power and crypto analyses, crypto suites must be updated. And new code means new bugs.

DeepSec 2016 Talk: I Thought I Saw a |-|4><0.- Thomas Fischer

Threat Hunting refers to proactively and iteratively searching through networks or datasets to detect and respond to advanced threats that evade traditional rule- or signature-based security solutions. “But what does this really mean?”, asks Thomas Fischer. “And what real impact does it have on the security team? Can we use threat hunting to provide a process to better detect and understand when you’ve been breached?”

More and more security data is being produced and usually aggregated into a central location or body to hopefully take quick and informed decisions on attacks or compromises amongst a mountain of data. When you start to include data gathered from your endpoints the amount of data starts to explode exponentially. This level of data provides us with a large amount of visibility. But is having visibility enough?

What if a more thoughtful and intelligent way of generating alerts could draw an analysts attention to the right place at the right time? This would provide context or even flag indicated suspicious behaviour that can become the starting point of a hunt.

In his talk Thomas Fischer will explore this theory and establish working foundations of what threat hunting is and look at some of the challenges associated with gathering large sets of data. This will give us a foundation to look at how we can improve and explore implementing an intelligent threat hunting model to drive the investigation process. We asked him some questions beforehand.

Please tell us the top 5 facts about your talk.

Threat Hunting is the new thing to detect malicious activities in your environment. In the talk we look at what it takes to do threat hunting, the challenges in putting into place, and how to deal with the volume of data. While most threat hunting pitches talk about using network based data, this talk looks at what kind of end point data can be used, the impact it can have on data volumes and what to look for to start the hunt.

How did you come up with it? Was there something like an initial spark that set your mind on creating this talk?

This talk is essentially a story about how to analyse a ton of data and what methods can help. It was born from my own experience into looking at what trends in IR are going on.

Why do you think this is an important topic?

It’s important because current automated solutions no longer suffice in detecting the “bad guys”. We need better methods and processes to combat these creative attackers.

Is there something you want everybody to know – some good advice for our readers maybe?

In this talk, I share some experiences in what and how to look at threat hunting as a method for detecting malicious activities. Threat hunting is becoming the current in-thing for marketing – hopefully this talk will clear up what threat hunting really means for incident response.

A prediction about the future – what do you think will be the next innovations or future downfalls when it comes to particularly your field of expertise / the topic of your talk?

Machine learning will play an important part of IR in the near future. As humans we won’t be able to process the volume of data being generated for IR. So machine learning is the natural next step to highlight “things” that need to be responded to…
