When a young Eva Kollisch arrives as a refugee in New York in 1940, she finds a community among socialists who share her values and idealism. She soon discovers ‘the cause’ isn’t as idyllic as it seems. Little does she know this is the beginning of a lifelong commitment to activism and her determination to create radical change in ways that include belonging, love and one's full self. In addition to Eva Kollisch’s memoirs Girl in Movement (2000) and The Ground Under My Feet (2014), LBI’s collections include an oral history interview with Eva conducted in 2014 and the papers of Eva’s mother, poet Margarete Kolllisch, which document Eva’s childhood experience on the Kindertransport. Learn more at www.lbi.org/kollisch . Exile is a production of the Leo Baeck Institute , New York | Berlin and Antica Productions . It’s narrated by Mandy Patinkin. Executive Producers include Katrina Onstad, Stuart Coxe, and Bernie Blum. Senior Producer is Debbie Pacheco. Associate Producers are Hailey Choi and Emily Morantz. Research and translation by Isabella Kempf. Sound design and audio mix by Philip Wilson, with help from Cameron McIver. Theme music by Oliver Wickham. Voice acting by Natalia Bushnik.

The "O" in OT (hackerhotel2025) 37:32

vor 13 Tagen37:32

37:32

Operational Technology (OT) is vital for industrial processes, yet strategic understanding of OT’s security complexity is often lacking at the executive level. This presentation emphasizes the need for organizations to approach OT as a strategic priority, highlighting its unique challenges—such as legacy systems and non-negotiable uptime—amid rising cyber threats targeting critical infrastructure. By fostering executive insight into OT management, organizations can improve resilience, enhance security, and gain a competitive edge, ultimately positioning OT as an asset in operational stability and corporate strategy. This presentation, titled "The 'O' in OT," explores the importance of executive-level understanding of Operational Technology (OT) within strategic frameworks. It highlights the distinct challenges OT faces compared to IT, including legacy infrastructure, strict uptime requirements, and rising cyber threats. Participants will gain insight into how a strategic focus on OT security and management enhances organizational resilience and competitive strength. By bridging the gap between OT’s operational demands and executive decision-making, this session outlines steps for integrating OT into a cohesive, secure, and future-ready corporate strategy.

Helpful hackers preventing evil hackers from crashing the grid (hackerhotel2025) 50:11

vor 13 Tagen50:11

50:11

The European electricity network has become a ‘smart grid.’ This offers many opportunities for sustainability but also makes our energy system more vulnerable to digital attacks. In a time of increasing threat of hybrid warfare, the government and the energy sector realize that we as a society must prepare for possible disruption of the energy system and do everything we can to prevent it. Various institutions test smart devices, set safety standards, and monitor compliance with these standards. However, parties such as our grid operators only have control over the energy grid equipment up to the front door. They are not allowed to look beyond the electricity meter, where most smart equipment is located. DIVD is allowed to do this and by identifying devices that can form a botnet, DIVD helps to make the smart grid more secure. DIVD has been conducting research into vulnerabilities in equipment of the energy system, such as charging stations, solar panel inverters, home batteries, and (Home) Energy Management Systems. Previous findings have led to several parliamentary questions and follow-up actions by authorities such as RDI, the Dutch Authority on Digital Infrastructure. With the CVD in the Energy Sector project, DIVD will set up a research and education line with the DIVD.academy in collaboration with the energy sector to reduce the digital vulnerability of our energy system. DIVD will also build a hardware lab to test devices and scenarios. You may join too and help to save the grid. In this talk, we will demonstrate how we could have generated outages using zero-days we found in solar converters and electric car chargers. But we also did it with just one user-password combination… The European electricity network has become a ‘smart grid’. Consumers are not only users but also producers of energy. More and more devices are connected, smart and online, so supply and demand can be more easily matched. This offers many opportunities for sustainability and possibilities for new players to enter the market. But also makes our energy system more vulnerable to digital attacks. In a time of increasing threat of hybrid warfare, the government and the energy sector realize that we as a society must prepare for possible disruption of the energy system and do everything we can to prevent it. In the Netherlands and Europe, various institutions test smart devices, set safety standards, and monitor compliance with these standards. However, parties such as our grid operators only have control over the energy grid equipment up to the front door. They are not allowed to look beyond the electricity meter, where most smart equipment is located. Being an independent non-profit research institute, DIVD is allowed to do this. By looking for devices that can form a botnet, DIVD helps to make the smart grid more secure. DIVD has been scanning the entire internet for vulnerabilities since 2020 and reporting them to the owners of systems. This may involve known vulnerabilities (Common Vulnerabilities and Exposures), new vulnerabilities (Zero-days), leaked credentials (username-password combinations) and online sources that are unintentionally accessible. DIVD is also a CVE Numbering Authority (CNA) and can publish new vulnerabilities. Our way of working is supported by the parties responsible for digital security in the Netherlands, such as NCTV, NCSC, AIVD, police, and many cyber security companies. In addition to these activities, DIVD also conducts research into vulnerabilities in the equipment of the energy system, such as charging stations, solar panel inverters, home batteries, and (Home) Energy Management Systems. Previous findings have led to several parliamentary questions and follow-up actions by authorities such as RDI, the Dutch Authority on Digital Infrastructure. With the CVD in the Energy Sector project, DIVD will set up a research and education line with the DIVD.academy in collaboration with the energy sector to jointly reduce the digital vulnerability of our energy system. In 2025, we will: - Incorporate all energy-related research by DIVD into a research line under a Research Lead Energy. - Establish structural partnerships with the energy sector to jointly resolve vulnerabilities. - Build our own hardware lab where we will test peripheral equipment for security and collaborate with other hardware labs. - Set up our CNA to receive, process, and publish CVEs of digital solutions used in the energy system. Share research findings with authorities to support their enforcement. DIVD.academy familiarize students with basic knowledge of energy systems and energy equipment and involve them in practice-oriented research. - Develop teaching materials for the installation sector and training courses to increase awareness of vulnerabilities in the energy system. - Share our knowledge via hacker events and security conferences. In this talk, we will demonstrate how we could have generated outages using zero-days we found in solar converters and electric car chargers.

How Thermonuclear fusion works, free energy without waste (hackerhotel2025) 37:10

vor 13 Tagen37:10

37:10

Nuclear fusion is a clean safe energy. Fusing hydrogen nuclei to release an enormous amount of energy. This talk will cover: - A recap of the physics that makes fusion work - How to build a fusion reactor at home - How nuclei collide and what is needed to the coulomb barrier - Challenges in how to scale it up and make it generate more power - How far are we to have fusion energy on the power grid - Current technical challenges in fusion - How we can solve problems using machine learning Nuclear fusion promises a clean, safe, and abundant source of energy by fusing hydrogen isotopes to release more power than is put in. In this talk, we will start by clarifying the fundamental physics of fusion—how overcoming the Coulomb barrier allows two hydrogen nuclei to fuse. We will then explore the path to industrial-scale fusion power, focusing on international prototypes such as ITER, designed to demonstrate an energy output of Q=10 (50 MW in, 500 MW out). Alongside the incredible engineering achievements involved in building such large machines, we will discuss the complexities of controlling high-temperature plasmas, mitigating disruptions, and managing edge-localized modes (ELMs). Throughout the talk, we will highlight novel control and diagnostic strategies, including machine-learning-based models that can aid real-time plasma monitoring and regulation. Ultimately, we will address how these technologies, with deeper physical understanding, can bring us closer to fusion’s full potential as a reliable and low-waste energy source.

A criminal, and victim view of phishing and phishing panels, live of stage. (hackerhotel2025) 51:23

vor 13 Tagen51:23

51:23

The Dutch Tax and Customs Administration deals with criminals claiming to be representatives of the organization and contacting the public with phishing emails daily. In this presentation, we will take you into the world of the criminals sending phishing emails and the recipients of the phishing mail. A live phishing demo is included. This presentation will show several examples of daily phishing that the Dutch Tax and Customs Administration deals with. The Dutch Tax and Customs Administration receives over 60,000 reports of phishing every year. The second part of the presentation includes a live demo of a phishing panel. Using a phishing panel ensures the phishing victim pays for purchasing a 75" OLED TV without knowing it. The TV is delivered to the cybercriminal's address. All of this is live on stage.

It's one thing to plan a vacation trip to Cancun if you have a Dutch passport. It's entirely another to find a way to safety if you have an Egyptian passport. It's one thing to plan a vacation trip to Cancun if you have a Dutch passport. It's entirely another to find a way to safety if you have an Egyptian passport. We are experts in moving people to places that various governments would rather we didn't. The global immigration, customs, and travel system is an absolutely massive technological and human system designed to make sure things happen according to the government's agenda. We have our own agenda, and it all makes for great hacking potential. Insert clever engineering, some interesting math, more than a bit of skullduggery, and you end up with our routing system and what we humbly suggest is an epic hack for a life saving purpose.
