OWASP Introduction, Welcome and News - Sam Stepanyan, Andra Lezza, Sherif Mansour - OWASP London Chapter Leaders
"North Korea: The Great Recruitment Firewall" - Mariya Hristova
North Korean spies are lurking everywhere, but especially in the hiring pipeline. Disguised as the perfect candidate to try and snag a position in a company where they can espionage away!
Recruitment is the first point of contact for all candidates so in this talk I will go over how I recognise fraudulent candidates without descending into unfounded bias. I’ll go over some recent examples and give some practical guidance of what you can do if you are not sure that the person opposite you is who they say they are."Vesta Admin Takeover - Exploiting reduced seed entropy in bash $RANDOM" - Adrian Tiron
Vesta is a lightweight, web-based control panel that simplifies Linux server management, appealing to users seeking an intuitive alternative to traditional platforms like cPanel and Plesk. This presentation will examine a critical flaw in Vesta: an admin takeover exploit resulting from reduced seed entropy in the Bash $RANDOM variable. By transforming what was once a theoretical attack into a practical one, we successfully reduced the brute force domain of the seed by over 98%. This allows attackers to generate predictable random values, compromising the security of passwords and tokens. We will discuss the implications of this vulnerability and highlight best practices for enhancing server security in real-world applications.
"Securing AI Agents: Identity Strategies for Safe API Access" - Gary Archer
As organizations adopt AI-driven tools and workflows, new security challenges arise around how AI agents securely access APIs. In this session, Gary explores how best practices for connecting AI agents to APIs are evolving, and outlines the essential identity and security building blocks organizations should put in place for the emerging AI era. The talk focuses on architectural principles and patterns rather than specific vendors or products.
SPEAKERS:

An enthusiastic amateur in all things tech, but with a personal crusade to help improve UX and UI in open source tools. If we want to usher in the year of the penguin, we have to pay attention to that stuff! In my spare time I like to break HR Tech or volunteer my time and knowledge to help companies and candidates/employees meet each other in right way.
