ABSTRACT: Ever since OpenAI released ChatGPT, LLMs have been applied to the most diverse domains, from education to medicine. However, what they basically do is to look for patterns in huge amounts of text and use those patterns to guess what the next word in a string is. Having no access to the real world, LLMs are therefore great at mimicry but show important limitations when employed for critical tasks, which may affect human well-being, social justice, and access to digital services. This talk will discuss all the above issues, highlighting the risks but also the huge potential of LLMs. BIO: Sara Tonelli is the head of the Digital Humanities research unit at Fondazione Bruno Kessler since 2013. She holds a PhD in Language Sciences from Università Ca’ Foscari in Venice and is a member of the Center of Computational Social Science and Human Dynamics jointly with the University of Trento.

ABSTRACT: Controlling groups of autonomous vehicles from a wireless network requires low delays, high reliability, and computing power close-by. Even though 5G cellular networks will provide these ingredients, high delays or connectivity interruptions may still lead to catastrophic consequences. We will present a novel solution to tackle these issues, based on a balanced mix of network, computing, and vehicle autonomy management. We will then discuss how to break it up, so that autonomous vehicles can bend traffic laws in case of emergency. BIO: Paolo Casari is an associate professor at the University of Trento, and an enthusiast of communications and networking in challenged conditions, both above and -why not- below the water.

ABSTRACT: Industrial robots are complex cyber-physical systems used for manufacturing, and a critical component of any modern factory. These robots aren't just electromechanical devices but include complex embedded controllers, which are often interconnected with other computers in the factory network, safety systems, and to the Internet for remote monitoring and maintenance. In this scenario, industrial routers also play a key role, because they directly expose the robot's controller. Therefore, the impact of a single, simple vulnerability can grant attackers an easy entry point. The talk will discuss how remote attackers are able to attack such robots up to the point where they can alter the manufactured product, physically damage the robot, steal industry secrets, or injure humans. BIO: Stefano Zanero received a PhD in Computer Engineering from Politecnico di Milano, where he is currently a full professor with the Dipartimento di Elettronica, Informazione e Bioingegneria. His research focuses on malware analysis, cyber-physical security, and cybersecurity in general. Besides teaching “Computer Security” and “Digital Forensics and Cybercrime” at Politecnico, he has extensive speaking and training experience in Italy and abroad. He co-authored over 100 scientific papers and books. He is a Senior Member of the IEEE and the IEEE Computer Society, which has named him a Distinguished Lecturer and Distinguished Contributor; he is a lifetime senior member of the ACM, which has named him a Distinguished Speaker; and has been named a Fellow of the ISSA (Information System Security Association). Stefano is also a co-founder and chairman of Secure Network, a leading cybersecurity assessment firm, and a co-founder of BankSealer, a startup in the FinTech sector that addresses fraud detection through machine learning techniques.

ABSTRACT: Log stealers are a type of malware that steals user credentials from a compromised computer. Criminals deliver stealers through a cracked version of software, causing the user to install them without even realizing it. They can recover usernames and passwords saved in browsers, as well as personal data, cookies, and system information. Logs stolen in this way are then offered for sale in various deep and dark web marketplaces. With our OSINT and CTI platform SATAYO, we monitor any evidence related to our customers to protect and safeguard their business perimeter. BIO #1: I am Mirko, a Technical Consultant at Würth Phoenix. I work in the Cyber Security Team together with Francesco, but we usually handle different things. I'm mainly part of the Blue Team where I develop procedures, documentation, and features for our SOC. I also analyze multiple interesting pieces of evidence and have a lot of fun :) BIO #2: I'm Francesco and I'm currently working as a technical consultant at Würth Phoenix with Mirko. Here I mainly develop the Cyber Threat Intelligence platform SATAYO, my "little child" - even if it's not so little anymore - but I also analyze the evidence found and help the customers understand and mitigate them.

ABSTRACT: We're used to thinking of technology as always progressing, and in terms of hardware that's definitely true: CPUs are getting more powerful, memory cheaper, networks faster, and so on, forever. But why does it feel like actually using computers is getting slower and shittier? Abundant computing resources and a culture of optimizing for developer productivity above all else have led to a situation where most hardware improvements are instantly negated by software inefficiency. This is a problem known from other domains (such as traffic flow), where increasing capacity is paradoxically not reducing but rather increasing the load on the system, resulting in a worse overall outcome. This talk discusses how we could approach this problem as a field, and makes some provocative recommendations — such as getting a worse computer. BIO: Tobias Bernard is an Italian interaction designer based in Berlin. He's a member of the GNOME design team and works for Purism on the Librem 5 team. When he’s not doing GNOME stuff, he's working to avoid climate disaster through mass civil resistance.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
