Talks 2021

Tails (Fails) from the trenches 2021

A talk by Edwin van Andel

Edwin van Andel will take you on a ride through the beautiful, but sometimes scary, woods of bugs, fails and wonders, located in the misty valley of infosec.

There will be tales of misdirected focus. There will be burning arrows flying towards the anonymous clientele of Zerocopter’s bug-bounty and coordinated vulnerability disclosure platform. And we will gaze at the sunset over the immortal fields of stupidity.
Edwin will discuss and gives examples of beautifully chained exploits, utterly stupid designs, fails and the always funny owner’s responses. Fun, laughter and tears as we cool off and swim together in IoT infested waters. While always reflecting back to the key of all his presentations: Hackers can help.

Will you hop on for a 45 minute 2021 fully updated ride through these hidden woods? Visual stupidity included as always!

His dream to bring the brilliant minds of all hackers he knows together in one room and to hack everything that is brought in is something that he is getting closer to.

In addition, together with the “Guild of Grumpy Old Hackers”, he is actively guiding and leading young hackers in the right direction in order to create his ultimate goal – a safe society through a safer internet.

Gone in 45 minutes… War stories from incident response

A talk by Fabio Viggiani and Fredrik STÖK Alexandersson

A story-driven technical session, mixing incident response, forensic analysis, malware reversing, recovery operations, and threat intelligence research. We will share our learnings from investigations of attacks conducted by cybercriminals and state sponsored actors, by walking you through exciting war stories from incident response missions we conducted during 2020 and 2021.

Getting that phone call telling you to get ready to start an incident response mission. High stakes, adrenaline rising, and a lot of potential things that can be done, but time is critical. Where do you start? What do you do?

We want to share our learnings from the many incident response missions we have done, to help you look for the right things and save time. We will dig through some stealthy implants we came across, recovery operations where we learned important lessons, as well as some effective tricks such as extracting RDP cache data to reconstruct the visual desktop of the threat actor.

Based on indicators collected from investigations, we will talk about how we can follow the threat actor and their operations, what we can learn from it, and how to use threat intelligence to enhance anything from Red Team to incident response.

Exploring memory corruption in real-time operating systems

A talk by Lars Haulin

Real-time operating systems (RTOSes) are very specialized for their purpose. They are highly optimized and often written in a low-level programming language to be fast, but this also makes memory corruption vulnerabilities an issue to consider.

There are many RTOSes available, and many have mechanisms in place to mitigate the exploitability of memory corruption, but how effective are these mitigations?

This talk will present some common RTOSes, show their internal memory layout and shared features and what exploit mitigations they provide.

The talk will also introduce a dockerized playground framework to hands-on explore the internals of some RTOSes and their protection mechanisms.

My Fuzzy Driver

A talk by Mark Cherp and Eran Shimony

Drivers are everywhere; it does not matter if you use Linux, Android, Windows, or Solaris :). They are a prime target for vulnerability research because of their high level of privilege and the fact; they are accessible from user-land. By harnessing the power of a great fuzzer, kAFL that is, using the advanced technology of Intel PT, and sugar coating with some driver-specific grammar, we set out on a journey to find bugs in modern kernel code, agnostic to the source code.

False Flag – dealing with a tainted crime scene

A talk by Leif Nixon

The Large Hadron Collider at CERN is supported by a large global cooperative infrastructure for scientific computing. Securing this infrastructure means preventing, detecting, and resolving security incidents as early as possible, while trying to overcome technical, organizational and cultural challenges. Working in this environment is a rollercoaster ride where you never know what will happen next.

One day, for example, it was discovered that a number of European supercomputers were all mining Bitcoin. This is the story about that incident, about French bureaucracy, and how the culprit was eventually identified.

Oh, and quite a lot of low-level filesystem forensics.

About speaker

Leif Nixon has been dabbling in IT security since the previous millennium. He has alternately hacked and defended all sorts of stuff, ranging from thermostats to supercomputers. This has left him depressed, embittered and cynical. These days, he works at Sectra Communications, defending critical infrastructure.

The latest crypto achievements from the FRA

A talk by Vesa Virta

Latest crypto breakthrough from the FRA, that we are allowed to talk about.

After invading Norway in 1940 the German Wehrmacht demanded to use Swedish telegraphy wires for communication to Berlin. This gave Swedish intelligence an opportunity to intercept information, provided that the German crypto device “der Geheimschreiber” could be cracked.

About speaker

Vesa is a museum guide at the National Defense Radio Establishment in Sweden. With 25 years of experience in the IT-security/intelligence arena he has some interesting stories that he unfortunately can’t share. However infosec as a field is older than the Internet, and there are some cool stories to be told that are no longer classified.
