PepsiDog: inside the rise of a professional Chinese phishing actor

Thursday 25 September 15:00 - 15:30, Red room

Stefan Tanase & Ionut Bucur (CSIS Security Group)

Building on last year's investigation into a massive Chinese package redelivery smishing syndicate, this presentation delves deeper into one of the key actors briefly touched on in the previous research.

PepsiDog is a threat actor that exemplifies a new level of professionalism, operating as a "developer-first" entity in the phishing ecosystem. By selling advanced phishing kits and offering phishing-as-a-service (PhaaS), they provide tools that enable global targeting of individuals and institutions, often through package redelivery scams.

This research highlights how this actor differs from others in scale, sophistication, and operational structure, demonstrating the ongoing evolution of threat actor capabilities. A day in the life of a threat researcher investigating this group will offer attendees a behind-the-scenes look at the challenges of unravelling their operations.

Additionally, we'll explore their technical innovation, the expanded adoption of new cash-out mechanisms, and how their kits are being sold and deployed globally.

Key findings and updates for attendees include:

  • Insights into how this actor designs and markets phish kits to other criminal groups, enabling widespread and efficient phishing campaigns.
  • A peek inside the panel demonstrating the actor's sophisticated phishing kit, including their modular and customizable features designed for global targeting.
  • Analysis of the steadily increasing number of compromised credentials and financial data linked to this actor's operations over the past year.
  • Examination of the actor's growing influence and their collaboration with other Chinese groups exhibiting similar tactics, techniques and procedures (TTPs).

This session, tailored for both technical and non-technical audiences, will provide actionable insights into the professionalization of cybercrime and offer strategies for detecting and defending against such advanced threats.
