Given the critical significance of cybersecurity in light of the rapid proliferation of AI, a dedicated conference track was exclusively focused on security issues. The track centered on exploring the utilization of AI in intelligence gathering and analysis, threat detection, alert investigation, security posture analysis, and other pertinent areas to boost the effectiveness of security teams in their daily operations.

AI at the Service of Democracy and Truth

In the Fake News track, several of the talks focused on the AI tools that can efficiently detect fake images and stories online, identify social media bots and trolls used for commercial and political influence, and uncover deep fakes, which have inundated the social media recently in massive disinformation or influence campaigns. 

 

“The Russia-Ukraine war was the first war fought on social media,”—Tom Alexandrovitch, Executive Director of the Defense Division, Israel National Cyber Directorate (INCD)

 

Zachary Elisha Bamberger, from the Technion, presented the AI-powered persuasive argumentation agent developed to combat hate and misinformation online in the wake of October 7. 

The underlying principles of the agent that posts comments under anti-Israeli content on social media include establishing trust by citing sources and figures of authority, effectively using logic and complex reasoning, and leveraging emotional appeal.

The solution can adjust the length and tone of the comments, as well as the level of formality and political and ideological stance to suit the target language and culture. It is also capable of understanding context and captions.

Using AI on social media provides for faster and more impactful responses across multiple platforms.  The AI agent can also predict how popular the content will be and estimate confidence in the response. In addition, it can report hateful posts found online.
