Day one, 7th November 

Arun Mane, Founder, and Director @ Amynasec Labs LLP

Presentation title: Hacking ICS devices for Fun

  • ICS stands for the Industrial control system and is critical for every nation, as teach one is connected with every infrastructure.
  • ICS Jargons: SCADA (Supervisory control and data acquisition) is a type of ICS / HMI (Human-machine interface) and RTU (Remote terminal units), PLC (programmable logic controller)
  • Why the need for ICS Security: ICS is the backbone of each nation’s manufacturing effort and plays a critical role in each nation’s wealth creation, known malware: Stuxnet, Black energy, these ICS systems are also vulnerable.
  • Challenges: lack of knowledge, industrial experience needed, hardware setup, cost of hardware
  • How to overcome? Try to understand communication protocols, use simulators (Gaspoy, Modbus.py library, Conpot, ScadaBR, ModbusPal
  • Useful tools: Nmap, Wireshark, Mbtget, GasPot commands, PLCScan, Metasploit auxiliary/scanner/SCADA

Alex Matrasov, Offensive Security Research Lead @Nvidia

Presentation tile: The Advanced Threats Evolution: Researchers Arm Race

  • the average time of vulnerability disclosure in firmware – 6 to 9 months
  • the challenge of understanding attack tactics or creating the right mitigation is related to mindset difference between attacker and architect
  • SeaBIOS / Coreboot in the cloud
  • BMC in many cases expose the different path to update BIOS
  • Halvar Flake’s wisdom: “We can’t check the firmware origin”
  • Hardware Root of trust

Martin Zember, Red Team @ Zembered Teaming

Presentation title: Why usual pentests suck?

  • The talk includes different stories from the Red Team involving a network penetration test, password guessing, email spear-phishing, phone calls, or accessing the building. 
  • How to get inside a building guarded all time, with cameras, cards, a fence around and other security measures? What engagements to use?
  • Getting inside isn’t easy, even though they knew much and had access to the internal network, because the customer wants to know what: an attacker with skills / without IT skills can achieve
  • What did they achieve: access to the building, to own cloud.
  • Summary: the customer specified the broad scope of the test, and was satisfied with the results.

Inbar Raz, Security Architect & Razier Einhorn, Technical Product Manager @Argus Cyber security

Presentation title: Under Pressure: Real-world damage with TPMS spoofing

  • TPMS (Tire pressure monitoring system) – a device that measures the air pressure of a car
  • When you deal with one vehicle, you have to receive, analyze and parse, modify and retransmit, which means you have spoofed a TMPS message/signal.
  • every single wheel of the car will have a unique ID.
  • During the research, they learned that it’s hard to get a good signal, but you need to do the research about the target to understand more and find the signal and extract the documentation needed.
  • Collecting multiple packets for statistic analysis to detect patterns and other things, such as TIre ID, CRC parameters.
  • Manchester encoding helps to identify when a packet ends and when it is corrupted or not.
  • Experimenting with the transmitter setup to see how far you can spoof the signal
  • backend setup – > multiple field-deployed Rasperry pie devices
  • Challenges: multiple modulations and encoding methods, multiple vendors and packet formats and signal synchronization
  • Mitigation to avoid this: make sure you encrypt the transmission, polling-only operation, correlate the signal with other sensors you already have in your car,
  • The number one problem is us, the humans: Keep your eyes on the road. Lives depend on it. 
  • As hackers, we know that where there’s a will, there is a will. 
  • Failure is part of the learning process. Research is about failing.
  • Recommended talk to watch: Ange Albertini – HacK.lu – October 2017

Mircea Hasegan, Software Engineer @Ixia

Presentation title: Consensual Surveillance

  • main features for a device (watch) that monitors children: call filter, tracking, the baby monitor
  • explaining your kid about the online risks, privacy, and why parents need to monitor their children to avoid the danger they are exposed to
  • when you buy the watch, you need to set the initial configuration, which might look like a difficult task to do
  • The flow: Once configured, sent data to a server, then you have an application to use, plus a Unique ID associated with the app, and you start seeing the info you are looking for.
  • Devices evolve, no matter the type, but the thing is consent. How do you use these devices the right way? It’s sensitive stuff and should be used carefully.
  • Children should communicate with their parents and be open about using the device and the implications of the risks.

Jayson E. Street, VP of Infosec @Sphereny

Presentation title: I PWN thee, I PWN thee not!

  • We need to get our people to protect the technology
  • Customers say: We need a wall to protect from APTs and we’re gonna make the APTs pay for it
  • APT= “Adequate Phishing Technique”
  • Give employees something to look up to and focus your efforts on educating them
  • Employees are not empowered (and educated) to question the unusual < – You have to make sure your employees are aware of this, so educate and empower them!
  • Public spaces that are well monitored and highly visible – > “your lobby is not there to be comfortable, but to get people verified”
  • it’s not about security, it’s about security fear
  • Sometimes we have people monitoring things, but they lack critical thinking.
  • What does your SM profile say about you?  – Educate employees about what and how to do at Social Media
  • Insider threats: sometimes they come from inside the house. Your employees make mistakes because they are not educated properly.
  • Phishing is one of the leading causes of compromise but do your employees really take it seriously? -> phishing attacks reach the highest level in three years.
  • Do you vet your security systems to make sure they are operating as intended?
  • If your company gets breached, DO full disclosure, communicate and quickly respond to this because it matters. Share the information that you got pwned.
  • Educated and empowered users, can you ever have enough?
  • It’s your responsibility (as a company) to properly educate your users and focus on this.

Konrad Jędrzejczyk, VP (Cyber Threat Defense) @Credit Suisse

Presentation title: Your Face Isn’t Yours Anymore

  • the future is NOW because there is a lot of money to be made: VoD and games where you can choose your favorite actorS, poor man holodeck with VR, counter anti-forensics for video feeds and many more
  • AI will not kill us. People who trust it will.

Chris Kubecka, CEO @Hypasec

Presentation title: The Road to Hell is Paved with Bad Passwords

  • With humor and charisma, Chris tells us about ISIS malware attacks and gives us details about how the incident management looks like when an embassy is hacked.
  • First incident email account breach -> password used for the Saudi Embassy: 123456 (weak password)
  • Diplomatic corps sent warning emails out (about extorsion) using CC, not BBC email.
  • Another extorsion attempt -> ambassador’s secretory personal email account was hacked
  • Saudi National Threat Day -> hackers asking for $50 million
  • Modern problems require modern solutions
  • Lessons learned: geopolitics, real human consequences, never trust gifts and be suspicious, always be prepared, and don’t panic in these particular incidents/situations.
  • It is imperative that we have freedom of the press.

Koen Vanhees, Security Operations Manager @Cegeka

Presentation title: Machine Learning and Advanced Analytics in Today’s Cyber Security

  • Every security pro is a data scientist
  • the classic approach for the SOC involving three aspects: technology, people and process
  • The future SOC: automation, people and intelligence which implies demand for new skills: scripting skills, taking care of all SOC components instead of following rules, have an open mind for new technologies beyond the comfort zone
  • Jupyter notebooks (interactive computing environment)
  • what to achieve with automation?  Today’s challenge: try to visualize, validate and detection using Machine Learning.

Milan Gabor, CEO @VIRIS

Presentation title: HID (Human Interface Danger)

  • Vulnerabilities found in Logitech products referring to the HID devices: keyboard, mouse, game controller, clickers, alphanumerical devices, medical devices, or any other device that meets USB HID specifications
  • attack scenarios: USB sticks dropping, classical payload with PowerShell, or classical usage to download and execute malicious files.
  • demo: inject into the communication / inject into clickers communication
  • demo: pair sniffing
  • ideas for HID attacks: USBSamurai – read about it here
  • Solutions>  Try using Bluetooth devices

Eva Galperin, Director of Cybersecurity EFF

Presentation title: #Spouseware and #Stalkerware: Where Do We Go from Here?

  • Most people don’t understand what kind of help they need.
  • You can change the system in the way that you’ll help other people
  • Stalkerware and spouseware –  commercial apps that are used to spy on people’s devices without their consent.
  • Example: A mobile spy app for personal catch cheating spouses
  • Darkcomet is a RAT developed by Jean Pierre LeSuer
  • the difference between #spouseware and #stalkerware is to understand deception (this is the key)
  • If you have one of these apps on your device, and you run AV on it, the chances that they are not found are extremely high
  • What can AV companies do? Detect them, label it as malicious, stay on top of it, and share samples.
  • What can Google do? do a better job policing the Google Play Store
  • What can developers do? Have one page/tab where the user can see all of their accounts that have access to their data
  • In the US, FTC recently takes action against Retina-X and banned it for making or selling software, until they write better software.
  • “I am not a hero or a superhero. You, guys, are!”
  • Look at the systems you wanna change. Find the population you wanna help and go do it!”

Day two, 8th November 

Jeff Man, Infosec Curmudgeon Security Weekly

Presentation title: More Tales from the Crypt…Analyst

  • Jeff is a highly experienced hacker who worked at NSA and tells amazing stories to the audience.
  • It is not enough to be digital, you néed to engage.
  • Reminder about Mental health hackers – Don’t forget to live your life. Work-life balance is important.
  • In the beginning, it was just the Internet security, not cyber
  • Books recommended by Jeff -> Dark territory: The secret history of cyberwar by  Fred Kaplan  /  The cuckoo’s egg by Cliff Stoll  (in this one you can learn about the hacking culture)
  • one time pad system used for encryption
  • Pretty Good Privacy (PGP), the popular mail encryption software program wrote by Phil Zimmerman – 
  • Primary attack tool used back in times – The Ping Command
  • Set user ID is a method used  to hack into the systems back then
  • reminder: Question everything

Alex J. Balan, Chief Security Researcher @Bitdefender

Presentation tile: Next-Gen IoT Botnets #3 – Moar ownage

  • Be mindful of how you read the news, so you can distinguish between real and fake news.
  • IoT=Hardware+OS+app+cloud
  • IoTs are just websites running on Linux with a significant attack surface on the mobile apps and cloud
  • most IOTs have moved to the could because it’s most secure and the botnets will not work anymore there (no ports available so attackers can operate)
  • current and upcoming IoTs implementations: not directly accessible to the Internet, more efficient management, decent usage of encryption, or modular architecture. However, not all implementations are that great.
  • S3 buckets –
  • next hen IoT botnets: buffer overflow in the cloud agent  (Kalay platform used for cloud communication), RCE command injection
  • Takeaways: IoT is a huge attack surface and is growing insanely fast / Leverage cloud communication to bypass NAT / Vendors need to pentest their product periodically & run bog bounty programs & have proper + unattended update mechanisms.
  • RCEs are often found in IoTs and it seems this won’t change anytime soon. More of the security research community needs to focus on this.
  • Everything is vulnerable, you just may have not found it yet.

Bia Lewis, CEO@Girls Who Hack

Presentation tile: The U.S. Election System, Can we fix it? YES, WE CAN!

  • The 12-year-old girl and the youngest speaker at DefCamp
  •  The election system has a HUGE attack surface: over 10,000
  • More states lack resources and technical expertise, using aging equipment,
  • everyone tries to hack the voting system. ALL THE TIME.
  • Election officials are not required to report these vulnerabilities
  • guidelines are out there, so let’s use them: OWASP, NIST Cybersec framework, OpenSCAP, S.A.F.E Act
  •  You need to test the reporting system with hackers, using the OWASP top 10 and detect vulnerabilities
  • 80% of US voting machines are made by 2 manufacturers: ES&S and Dominion
  • the voting machines – all closed source code
  • Paper ballots – > there are 2 ways to collect votes:  Handmade paper ballot and BMD (Ballot making device)
  • Voting machines in the cold storage -> how to secure it? Rember about software updates and apply them
  • What is the best voting system? Hand marked paper ballots  (counted by hand or scanner) and risk-limiting audits ( verify the scanner or hand counter)
  • What’s the fix for the voting system? 1. Look at the election system as a very hackable security problem for the start. 2. Train your developers and engineers and teach them to hack and think like a hacker. 3. Hire hackers to get a different perspective on your problem and are security-minded.

Mihai Belu & Razvan Stere, @Electronic Arts

Presentation title: Security meets the world of gaming

  • DevKits – hot stuff on the black market and are fully configurable.
  • Anti-piracy  – diminishing returns -> all games will be cracked if the offline play is possible, minimize player announce and performance hit, try to maximize time on the market
  • Anti-cheating – ensuring a fair and fun field of play – > detection and prevention/modus operandi is just like malware for cheaters in gaming/incentive for cheating: competitive gaming prizes now reach or surpass professional sports levels.

Steve McGregory, Senior Director @Ixia

Presentation title: Implementing Continuous Offense, to Measure and Monitor Cybersecurity Defenses

  • the solution to cybersecurity is the automation of self-hacking and remediation
  • Continuously improve the network with vulnerability assessment, breach and attack simulation, pentesting and red teams, pre-deploying security testing
  • What tools do hackers use? MITRE, Kali Linux, Empire, Metasploit
  • Breach realism – Simulate attacks across each phase of the cyber kill chain
  • Continuous validation of the enterprise-wide security infrastructure
  • Quantify the impact of the latest security breaches and perform a security assessment
  • If you can’t measure it, you can’t improve it. 
  • Educate network and security stuff – educate your people, enhance situational awareness for operators,
  • The most important thing today is your data, your information.

Jun Li, Senior Security Researcher @360 Security Technology

Presentation title: Secure them all—From Silicon to the Cloud

  • Silicon/Chip security – attacks vectors: boards, nodes (all types of devices)
  • Chip reverse-engineering methods: Decap ->: microprobe to connect inside the chip, FIB: Focused Ion Beam – Circuit editing, make the connection, cut the connection, RTL (Register-transfer level), Fault injection, side-channel analysis
  • Passive keyless entry system relay attack – demo followed 
  • “All protocols are secure until it is broken”
  • Steal cars via a cellular network 
  • Hardware security measures you should consider and implement = secure elements in ECUs, firmware encryption, and verification, mutual authentication among ECUs 
  • DO NOT trust anyone on the communication link, only rely on what you can absolutely control over to implement your security

Rosalia D’Alessandro, Security Associate Manager @Accenture IT

Presentation title: 5G: Need for a comprehensive Cyber Security Framework

  • 5G architecture allows more flexibility and high performance tailored for several B2B and B2C use cases
  • 5G threats: heterogeneous devices, the security of front hauling and backhauling links, heterogeneous access networks, new signaling protocols based in HTTP, resource sharing-> Everything is shared and opened, and it could be a security issue, user privacy->user identity is bounded to devices, complex ecosystem, untrusted external network exposure, supply-chain integrity.
  • 5G expands cyber risks, so there is a need to redefine the cyber strategy and try a new approach

Neil Roebert, Senior Information Security Consultant @F-Secure Consulting

Presentation title: Securing DevOps: Common misconceptions

  • DevOps – complicated environment that works together
  • DevOps refers to people – process – technology
  • the code that is produced is your product and on the other side, you have the users
  • the security-focused pipeline
  • Attack scenarios encountered: secret management (Creates barriers between your devs and product) -> if an attacker can register on GutHub, you can get access to your data found on the account, then the Configured Infrastructure (CI) and access to sensitive information.
  • Developer machines are getting easier to get access to due to most of them using unmanaged personal machines.
  • Key takeaways: overcoming the mindset that DevOps is just an ideology, understanding the technology and assessing often overlooked systems from a holistic perspective, building resilient systems that can withstand attack.
