According to a recent report covered by The Register, Chinese-linked threat actors remain embedded inside U.S. energy infrastructure networks, potentially preparing to sabotage critical operations.
This development represents a dangerous evolution in cyber warfare. Instead of immediate exploitation, attackers are quietly maintaining persistent access to operational technology environments that control essential services like electricity, pipelines, and water systems.
The implications extend far beyond the energy sector. They reveal why traditional cybersecurity approaches are failing and why organizations must rethink how they protect their systems.
The activity centers around a Beijing-linked cyber group commonly known as Volt Typhoon, which security researchers correlate with an operational technology threat actor called Voltzite.
Security firm Dragos reported that these attackers continued penetrating U.S. electric, oil, and gas companies throughout 2025 by compromising routers, cellular gateways, and other edge devices.
Once inside the network, the attackers moved deeper into industrial control environments.
What makes this campaign particularly alarming is the attackers’ objective. Researchers observed that the group was not primarily stealing intellectual property or financial information. Instead, their activity focused on learning how industrial processes operate.
According to Dragos CEO Robert Lee, the attackers had embedded themselves in infrastructure systems "for the purpose of taking it down."
This type of activity is known as pre-positioning. The attacker quietly establishes long-term access to critical systems so they can disrupt them later during geopolitical conflict or crisis.
The attackers went far beyond typical network intrusion.
Investigators observed them:
This information could potentially allow an attacker to manipulate industrial systems or shut down operations entirely.
Even more concerning, researchers noted that attackers were getting inside the control loop systems responsible for managing industrial operations.
This represents a shift from cyber espionage to potential cyber sabotage.
The Dragos report also revealed that the threat landscape is expanding.
Three new operational technology focused threat groups emerged during 2025:
These additions bring the number of tracked OT-focused threat groups worldwide to 26, with 11 active in 2025 alone.
This ecosystem approach means one group may gain access while another performs reconnaissance and a third prepares destructive capabilities.
The result is a coordinated cyber campaign against industrial infrastructure.
Most organizations still rely on a cybersecurity strategy built around Detect and Respond.
This model assumes that:
Unfortunately, nation-state attackers like Volt Typhoon are specifically designed to evade detection.
They often:
Government advisories have noted that these attackers frequently rely on stolen credentials and "living off the land" techniques that blend in with normal activity.
When attackers operate this quietly, detection-based security frequently fails.
By the time an intrusion is discovered, the attacker may already have deep access into critical systems.
To stop modern attacks, organizations must move beyond detection and toward Isolation and Containment.
Instead of trying to identify every malicious action, this approach prevents untrusted applications and processes from interacting with critical system resources.
Even if malware or an attacker enters the environment, they cannot:
This fundamentally changes the outcome of an attack.
Instead of a breach turning into a crisis, the threat is contained before damage can occur.
The lessons from the Volt Typhoon campaign are clear.
Attackers are no longer simply trying to steal information. They are preparing to disrupt operations and critical infrastructure.
Businesses of every size should assume that advanced attackers may already be attempting to gain access to their systems.
Relying solely on detection tools is no longer enough.
Organizations must adopt security technologies designed to prevent attacks from succeeding in the first place.
At CHIPS, we help organizations move beyond the outdated Detect and Respond model and adopt a modern cybersecurity strategy based on Isolation and Containment.
One of the most effective solutions available today is AppGuard.
AppGuard has a 10 year proven track record of stopping ransomware, malware, and advanced threats by preventing malicious actions at the endpoint. Instead of trying to identify every new attack variant, it isolates risky processes so they cannot damage the system.
This approach stops threats like the ones used in the Volt Typhoon campaigns before they can spread or compromise critical operations.
If you are a business owner or IT leader concerned about the growing threat landscape, now is the time to rethink your security strategy.
Contact us at CHIPS today to learn how AppGuard can help protect your organization and move your cybersecurity strategy from Detect and Respond to Isolation and Containment.
