it's a talk from a community perspective and I will share my personal story (not so much) and some aspects you wont find anywhere else:

Imagine working in your country’s cybersecurity center or CERT, and suddenly being reassigned to border control and deportation duties. Something is clearly broken and dangerously so.
What will you do as a cybersecurity professional?

News of the reassignments comes at a time when the U.S. is facing a wave of hacks targeting private industry and the federal government.

CTIArena: Benchmarking LLM Knowledge and Reasoning Across Heterogeneous Cyber Threat Intelligence
Cyber threat intelligence (CTI) is central to modern cybersecurity, providing critical insights for detecting and mitigating evolving threats. With the natural language understanding and reasoning capabilities of large language models (LLMs), there is increasing interest in applying them to CTI, which calls for benchmarks that can rigorously evaluate their performance. Several early efforts have studied LLMs on some CTI tasks but remain limited: (i) they adopt only closed-book settings, relying…

“The key reason, the ECIU says, lies in how British households use smart meters and flexible electricity tariffs. While petrol prices are broadly similar in both countries, UK electric car drivers can charge their cars overnight using cheap, surplus electricity at rates as low as 7p per kWh.”

Lossless Derandomization for Undirected Single-Source Shortest Paths and Approximate Distance Oracles
A common step in algorithms related to shortest paths in undirected graphs is that, we select a subset of vertices as centers, then grow a ball around each vertex until a center is reached. We want the balls to be as small as possible. A randomized algorithm can uniformly sample $r$ centers to achieve the optimal (expected) ball size of $Θ(n/r)$. A folklore derandomization is to use the $O(\log n)$ approximation for the set cover problem in the hitting set version where we want to hit all the …

Timeline Problems in Temporal Graphs: Vertex Cover vs. Dominating Set
A temporal graph is a finite sequence of graphs, called snapshots, over the same vertex set. Many temporal graph problems turn out to be much more difficult than their static counterparts. One such problem is \textsc{Timeline Vertex Cover} (also known as \textsc{MinTimeline$_\infty$}), a temporal analogue to the classical \textsc{Vertex Cover} problem. In this problem, one is given a temporal graph $\mathcal{G}$ and two integers $k$ and $\ell$, and the goal is to cover each edge of each snapsho…
