🚀 New Talk Confirmed for BSides Luxembourg 2026!

Leaky API Keys, Log Tampering, and Account Takeover – Aleksa Zatezalo

Modern cloud systems are highly secure in isolation, but real-world risk emerges at the seams — where services integrate. This talk explores how seemingly minor misconfigurations in logging pipelines, API integrations, and third-party services can quietly escalate into high-impact security breaches.

Through three real-world inspired vulnerability scenarios, the session demonstrates how leaked API keys from client-side logs, misconfigured S3 uploads, and insecure integrations (such as Supabase and financial data pipelines) can be chained into account takeover paths. The focus is on understanding the underlying anti-patterns rather than isolated bugs.

Attendees will leave with a structured framework to identify these cross-service weaknesses and practical remediation strategies that go beyond patching symptoms — targeting the architectural root causes that enable entire classes of exploitation.

Aleksa Zatezalo is a security engineer and software developer with experience in cloud security consulting, offensive security tooling, and contributions to Metasploit. He currently works at Praetorian and is OSCP-certified, pursuing OSCE3, with a strong focus on applied offensive security research.
