ABSTRACTS
The event will feature insights from TikTok's in-house experts, providing a unique look into how a global platform manages its security operations. The presentations will be led by representatives from our TMIRI pillar, specifically from the following teams, TDR, TI and VM.Insights on Enterprise Security Detection
This presentation explores practical insights into enterprise security detection and defense. It begins with real-world cyber incidents, highlighting global ransomware, APT attacks, and large-scale disruptions. By analyzing a typical intrusion process—from phishing emails to lateral movement and privilege escalation—it reveals how attackers penetrate corporate environments. The slides further explain the MITRE ATT&CK framework and its role in building proactive defenses. Enterprise practices are shared, including big data log collection, expert rules, and machine learning to detect abnormal behaviors across the attack chain. Finally, it emphasizes incident response as the “last mile” of defense, with metrics like MTTD and MTTR guiding continuous improvement. The key takeaway: effective security requires reducing detection and response time to minimize risks and strengthen resilience.Peek into our GSO Threat Intelligence Program
This presentation aims to introduce Threat Intelligence to newcomers in the field. It explores how the GSO Threat Intelligence team categorizes intelligence into Traditional, Business Risk, and Dark Web categories, and applies these concepts to a real-world case study on Business Risk investigations. Starting with an initial lead from a Telegram ad, we detail the intelligence gathering process, impact analysis, and how Threat Intelligence works can impact an organisation. The presentation concludes with a fun tidbit about the identities behind the Threat Actor.Patching the Gaps + Insights into our HackerOne Live Hacking Event
This presentation explores the product vulnerability management process in TikTok and provide insights on the experience of setting up public live hacking events (LHE) with HackerOne.LLMs: Your Next AppSec Tool, or Your Next Target?
Large Language Models (LLMs) are both a massive opportunity and a new risk. So, are they a trustworthy ally or just the next attack surface? This talk dives into both.First, we'll cover the AppSec perspective: how to use LLMs to supercharge the security toolings and accelerate daily workflows. We'll demonstrate how to move faster on security reviews, pentestings, code reviews, and more. Then, we'll put on our red team hats and introduce an agentic, AI-powered pentesting playbook, with practical guidance and real-world case studies on hacking AI applications.
You'll walk away knowing how to use LLMs for defense and how to guard your applications against this new generation of threats.

Attendees will engage in simulations and case studies that allow them to practice and refine their skills in protecting networks and systems against various cyber threats.
- White/Yellow/Green Team: These sessions will foster collaboration between offensive and defensive teams. We’ll address best practices in threat intelligence sharing, security policy development, and compliance measures. This integrated approach will highlight the importance of a cohesive cybersecurity strategy across different teams.
- Emerging Technologies: As technology rapidly evolves, this theme will focus on the latest advancements in cybersecurity, including artificial intelligence, machine learning, and blockchain security. Participants will gain insights into how these technologies are reshaping the cybersecurity landscape and explore practical applications to enhance their own security practices.
ABOUT THE WORKSHOP
Quantum safe technologies such as Quantum Key Distribution (QKD), are essential for long term security and guard against future quantum threats. Unlike classical encryption methods, which can be vulnerable to attacks from quantum computers, QKD distributes keys securely using the principles of laws of physics and is resilient against quantum attacks. By integrating quantum safe technologies such as QKD, businesses can enhance their cybersecurity infrastructure to withstand emerging threats, maintaining trust and confidence in their data protection measures.What's covered during the workshop
- Overview of quantum computing and quantum communications
- Quantum threats
- Overview of QKD and PQC in modern cryptography
- Introduction to the QKD protocol
- Integrating QKD to existing classical infrastructure
