“Beijing-linked hackers infiltrated American power, water, and communications networks, positioning themselves for potential disruption during future conflicts.”

More than espionage, Operation Volt Typhoon represents strategic preparation for digital warfare. By quietly embedding in U.S. infrastructure, Chinese state-backed hackers positioned themselves to cripple military and civilian systems if tensions over Taiwan erupt into conflict.

The Story

U.S. officials have confirmed that Operation Volt Typhoon, a state-sponsored cyberespionage campaign linked to the People’s Republic of China (PRC), infiltrated critical infrastructure networks across the United States and its territories, raising concerns about Beijing’s ability to disrupt key systems during a future geopolitical conflict.

According to reports from the FBI, the National Security Agency (NSA), and the Cybersecurity and Infrastructure Security Agency (CISA), the operation—active since at least mid-2021—focused on embedding long-term access into lifeline sectors vital to both civilian populations and U.S. military logistics. Targets included communications, energy, water, wastewater, and transportation infrastructure.

One particularly alarming discovery involved a U.S. electric grid, where Volt Typhoon actors reportedly maintained a covert presence for nearly 300 days without detection. Guam, a strategically significant U.S. territory in the Pacific, was also a primary target because of its potential as a launch point for U.S. military operations in the event of a crisis over Taiwan.

Unlike typical cyberespionage efforts aimed at data theft, Volt Typhoon’s tactics were designed for persistence and disruption. The hackers employed “living-off-the-land” (LOTL) techniques—using legitimate system tools already present in the victims’ environments—to execute commands, move laterally, and disguise their activity as routine network operations.

This approach allowed the group to evade traditional detection systems for extended periods. To further conceal their origins, the attackers routed malicious traffic through a botnet of compromised small office and home office (SOHO) routers, including outdated Cisco and NetGear devices.

The FBI dismantled this “KV Botnet” in January 2024, but cybersecurity experts say the group demonstrated resilience by rebuilding its infrastructure within months.

U.S. intelligence assessments suggest the campaign’s objective extended beyond intelligence collection. Officials believe Volt Typhoon was designed to establish a digital foothold within critical infrastructure that could be weaponized during a future crisis, particularly one involving Taiwan.

“If activated, these capabilities could delay U.S. military mobilization and create widespread societal disruption,” one senior U.S. defense official said on condition of anonymity.

While China has officially denied any involvement, U.S. officials point to veiled remarks made by Chinese representatives during a secret bilateral meeting in December 2024 as a tacit acknowledgment of the campaign. U.S. attendees interpreted the comments as a warning against further American support for Taiwan’s defense.

The campaign has been jointly attributed to a PRC state-sponsored group by Microsoft, the FBI, the NSA, and CISA. The group, tracked under various aliases including VANGUARD PANDA and BRONZE SILHOUETTE, remains under active monitoring by Western intelligence agencies and private cybersecurity firms.

“Operation Volt Typhoon underscores a long-term, strategic effort by the PRC to pre-position itself for potential disruption of U.S. infrastructure,” said CISA Director Jen Easterly in a statement. “The intent is clear: to be ready to strike if geopolitical tensions escalate.”

As U.S.–China relations continue to strain over Taiwan, trade, and cybersecurity, experts warn that Volt Typhoon represents a new era of state-sponsored digital warfare—one focused not merely on espionage, but on preemptive sabotage.

COUNTERMEASURES: Stay ready

In the event of a disruption to critical infrastructure—such as that posed by campaigns like Operation Volt Typhoon—the U.S. government recommends that families prepare an emergency supply kit (“go-kit” or “72-hour kit”) to sustain themselves in the event of power, water, communications, or transportation outages. Key items include:
