Introduction to DKnife AitM Framework

Cybersecurity researchers have recently uncovered a sophisticated adversary-in-the-middle (AitM) framework known as DKnife. This framework, operated by China-linked threat actors since at least 2019, is designed to target routers and edge devices for traffic hijacking and malware delivery.

The DKnife framework consists of seven Linux-based implants, each equipped with deep packet inspection capabilities and the ability to manipulate traffic. This allows the attackers to intercept and alter network traffic, facilitating the delivery of malware to compromised devices.

Key Features and Implications

  • Deep packet inspection for traffic analysis and manipulation
  • Malware delivery via compromised routers and edge devices
  • Ability to hijack traffic for various malicious purposes
  • Operated by China-nexus threat actors since 2019, indicating a long-term campaign

The discovery of the DKnife AitM framework underscores the evolving nature of cyber threats and the importance of robust cybersecurity measures, especially for network devices and edge equipment.

Security is a process, not a product.
