The Microsoft Red Team attacks ALL Microsoft services, continually – identifying critical, systemic risks, demonstrating authentic attack chains and techniques, and working with engineering teams, investigators, and incident responders to continuously improve their ability to protect, detect, investigate, and respond to real attacks.

Microsoft Red Team is launching the AI Adversary Lab (AIAL) in ILDC (Microsoft Israel Development Center), a new extension of the Microsoft Red Team, to address the growing threat of AI-enabled adversaries through deep engineering and applied vulnerability research.

The research team in AIAL will collaborate with global Red Team security vulnerability researchers and Red Team operators to analyze Microsoft's AI infrastructure, especially Azure AI services, to discover vulnerabilities, assess attacker impact, and improve resilience. We make Microsoft ready to face persistent, sophisticated adversaries by developing new methods to find, exploit, and mitigate security flaws.

As a Senior Security Researcher, you will lead proactive vulnerability research, developing novel proofs-of-concept and exploit chains that emulate real-world attackers. You will discover vulnerabilities across AI systems, validate exploitability, and work closely with engineering and product teams to drive remediation. The vulnerabilities you will find will impact hundreds of millions of users!
