Senior officials at the Defense Department say the Pentagon’s new cyber force generation model will help the military boot out Chinese threats from America’s critical infrastructure networks. A digital tactic known as “living off the land” has been a concern for U.S. officials in recent years as actors linked to China, such as Volt Typhoon, have…
Analysis Summary
# Threat Actor: Volt Typhoon (and associated Chinese actors)
## Attribution & Identity
**Attribution:** Explicitly linked to China by U.S. officials.
**Associated Groups/Aliases:** Mentioned alongside general "actors linked to China."
## Activity Summary
The actors, including Volt Typhoon, have executed a "deliberate campaign in order to compromise U.S. networks." The primary focus of this activity, as stated by the Defense Department, is infiltration within America's critical infrastructure networks. The goal of their presence in these networks is persistent access and movement.
## Tactics, Techniques & Procedures
- **Living off the Land (LotL):** The most significant TTP highlighted. Actors use "native commands and native features inside those networks" to conduct operations.
- **Evasion:** Utilizing native tools makes their activity resemble "legitimate traffic," thereby making detection difficult for defenders.
- **Movement/Persistence:** The use of LotL techniques facilitates lateral movement within compromised environments.
- **MITRE ATT&CK IDs:** Not explicitly mentioned in the provided text.
## Targeting
- **Sectors:** Critical infrastructure networks.
- **Geography:** United States (U.S. networks).
- **Victims:** U.S. networks generally; specifically mentioned as infiltrating the networks necessary for national defense operations and infrastructure integrity.
## Tools & Infrastructure
- **Malware Families Used:** None explicitly named beyond the general behavioral description of LotL.
- **Infrastructure:** Not detailed in the provided summary excerpts.
## Implications
The infiltration and persistent presence of Chinese actors utilizing LotL techniques pose a significant and persistent challenge to U.S. defenses because their activity blends seamlessly with normal network operations, complicating traditional signature-based detection methods. This requires a change in defensive strategy, as noted by the Pentagon's new cyber force generation model (Cybercom 2.0).
## Mitigations
- **Organizational Response:** The Pentagon is implementing a new cyber force generation model (Cybercom 2.0) specifically designed to help the military "boot out Chinese threats."
- **Defensive Focus:** The core requirement is shifting defenses to better detect activity that mimics native, legitimate traffic, moving away from relying solely on identifying external/malicious tools.
