Yossi Sassi - Fantastic Persistence: Creative backdoors & where you will NOT find them This presentation was held at #BSidesBUD2025 IT security conference on 21st May 2025. Who lurks in the clutter of signals & false-positives? Threat actors may come up with creative back doors to avoid detection, hacking systems without leaving trivial traces. In this session, we will look at different methods that these threat actors use to hide, explain indicators you are probably NOT aware of, and how you can expose them. This hands-on, full of demos session includes published open-source tools you can use to expose those threats and secure your systems.
