Colorful Vulnerabilities – How changing the colors of your keyboard might lead to privilege escalation

A talk by Tal Lossos & Eran Shimony

Have you ever felt excited about using a brand-new gaming keyboard? Have you dreamed of how you can increase your actions per minute while having many cool bright colors? Often we do not think about the repercussions of the peripheral devices we use, which might be a problem. In this session, we will outline our research process – analyzing and investigating Razer’s Linux kernel module, followed by finding a number of bugs that are oddly determined by the number of RGB colors you have, affecting the kernel itself.

I See What You’re Watching on SVT Play: Fast Identification of DASH Encrypted Network Traces

A talk by Romaric Duvignau

We present an attack capable of identifying streamed content from the web service SVT Play even when the said content is encrypted by HTTPS. The attack relies on finding recognizable and predictable patterns produced by the DASH streaming protocol in the packet traces. After building a 100k fingerprint database from all SVT videos, any video watched by nearby streamers can be recognized in as little as 15 seconds of packet capture. The viewing timestamp is also recovered making the attackers capable of mirroring live the encrypted streamed content on their own device simply via calls to the SVT play API.

An open-source implementation of our prototype is publicly available at

JavaScript Prototype Poisoning, an unexplored bug-class, and it’s everywhere

A talk by Christoffer Jerkeby & Anton Linné

A JavaScript prototype mutation vulnerability is a bug that occurs when the input data contains a structure resembling an object that is instantiated by the receiving application. The vulnerability can lead to Denial of Service, flow control alteration, input validation bypass and, in the worst case, arbitrary code execution. The vulnerability is commonly found when the application receives JSON input but can apply to any type of structured format that supports nesting. The presentation will cover demonstrations of current vulnerabilities and how they are exploited.

Scaling the Security Researcher to Eliminate OSS Vulnerabilities Once and For All

A talk by Jonathan Leitschuh

Hundreds of thousands of human hours are invested every year in finding common security vulnerabilities with relatively simple fixes. These vulnerabilities aren’t sexy, cool, or new, we’ve known about them for years, but they’re everywhere!

The scale of GitHub & tools like CodeQL (GitHub’s code query language) enable one to scan for vulnerabilities across hundreds of thousands of OSS projects, but the challenge is how to scale the triaging, reporting, and fixing. Simply automating the creation of thousands of bug reports by itself isn’t useful, & would be even more of a burden on volunteer maintainers of OSS projects. Ideally the maintainers would be provided with not only information about the vulnerability, but also a fix in the form of an easily actionable pull request.

When facing a problem of this scale, what is the most efficient way to leverage researcher knowledge to fix the most vulnerabilities across OSS? This talk will cover a highly scalable solution – automated bulk pull request generation. We’ll discuss the practical applications of this technique on real world OSS projects. We’ll also cover technologies like CodeQL & OpenRewrite (a style-preserving refactoring tool created at Netflix & now developed by Moderne). Let’s not just talk about vulnerabilities, let’s actually fix them at scale.

About Speaker

Popopizza – How to break the Dutch police bodycams for fun and pizza

A talk by Edwin van Andel

The Dutch police has been trying to collaborate with ‘private partners’, including the Dutch hacker community in the Netherlands, for years now (the great Public Private Partnership or PPP), with mild succes. So when they asked us what they could organise to get to know us, we replied with “invite us to hack police shit and eat pizza’s”. We thought we would never hear of them again. Surprise surprise, they eventually invited us in. So we created a team consisting of brilliant hard- and software hackers from the Dutch hacking community and went to the Amsterdam police station to try and hack some of their obsolete bodycams. Did we succeed? Come and find out and prepare to laugh your ass off!

About Speaker

Secure your code like NASA with Security as Code (SaC)

A talk by Joseph Katsioloudes

Following the lessons learnt from two missions of NASA to Mars, Security as Code (SaC) is the methodology of codifying security tests, scans, and policies. Security is implemented directly into the CI/CD pipeline to automatically and continuously detect security vulnerabilities. Adopting SaC tightly couples application development with security and vulnerability management, while simultaneously enabling developers to focus on core features and functionality. More importantly, it improves the collaboration between Development and Security teams and helps nurture a culture of security across the organization.
In this session, we will review lessons learned from DevOps to implement a successful DevSecOps culture, in particular how we can make developers contribute security checks with the SaC approach. We will introduce CodeQL, a language that allows us to implement security checks with code, and will demo how we can code queries for vulnerabilities and misconfigurations so they can be identified as soon as they hit your CI/CD pipeline.

About Speaker

When SysAdmin and Hacker unite: 21 One-Liners to make you convert from bash to Powershell

A talk by Yossi Sassi

Gotta love those one-liners! we all use Bash everywhere for everything, yet rarely do sys admins & hackers realize the real potential of PowerShell as a quickn’dirty “hacking tool” (open sourced on Mac/Linux/Windows). It has evolved greatly in the last decade to became the tool of choice for Windows Post-Exploitation by many, yet also for Sys Admins it is a dream of functionality and, well, ‘Power’. Indeed, with great power(shell) comes great responsibility. Join this fun session with highly technical hands-on demos, covering attacks, defending, forensics, malicious vectors, cryptography and other security & management related hacks! Scanning the entire internet, running fileless in memory without touching disk, running powershell without powershell and more, including Bypassing all PowerShell defenses in.. mmm, well, creative ways 🙂

Nation-state actors… No, it’s not all about phishing

A talk by Anastasios Pingios

The vast majority of threat research on nation-state actors reports initial access through various forms of phishing, but is this actually the case? This research looks into nation-state cyber operations from a different perspective. That of studying leaked material to identify how prominent are phishing attacks compared to other methods, and which are those other initial access methods. The objective of the presentation is to provide some food for thought on whether or not we are looking for APT activity in the right places, and which are those places in case you want to invest in security against advanced actors.

eBPF ELFs JMPing Through the Windows

A talk by Richard Johnson

eBPF tracing is a hot new technology in the EDR and infrastructure space providing high speed instrumentation and telemetry on events, processes, and network connections. Last year, Microsoft released a completely new implementation of an eBPF tracing system for Windows which is destined to become a primary telemetry provider in the near future.

eBPF for Windows has a complex architecture that leverages program analysis to verify unsigned user code via abstract interpretation before running it in a kernel context so integrity of the software is paramount. This research will be the first public work to analyze the new eBPF for Windows implementation for security vulnerabilities.

Our presentation will discuss the capabilities and security model of eBPF for Windows followed by details of the design and attack surface which will include the eBPF API, the trusted static verifier and JIT engine, and the kernel implementation of trace hooks and telemetry providers. During our deep dive into the implementation details we will uncover vulnerabilities at multiple layers and discuss how they were found with demos of fuzzing Windows eBPF components and real-time bug discovery.
