This week on “Uncanny Valley,” Andy Greenberg discusses sitting in on a war game simulating a cyberattack from the Chinese hacking group Volt Typhoon

A Chinese state-sponsored hacking group known as Volt Typhoon has spent the last three years embedding malware into critical infrastructure across the United States, positioning itself to disrupt essential services. This activity, described by some as "digital bombs" strapped to infrastructure, has prompted concerns about potential widespread societal chaos.
Initially, Volt Typhoon was believed to be targeting electric grids and telecommunication networks in the continental U.S. and Guam, likely with a focus on U.S. military facilities and surrounding infrastructure. The prevailing theory suggested these actions were in preparation for a potential Chinese invasion of Taiwan, aiming to delay a U.S. response.
However, subsequent analysis revealed that the group's activities extended beyond military targets to include civilian critical infrastructure, such as electric and water utilities, across the entire U.S. This includes smaller towns like Littleton, Massachusetts, raising questions about the broader motivations behind these intrusions. Experts now theorize that China might be seeking the capability to cause significant disruption and distraction within the U.S. during a potential crisis, such as a Taiwan invasion.
While Volt Typhoon has not yet initiated any disruptive cyberattacks, the groundwork laid by the group has spurred simulations and war games to assess potential responses. One such closed-door exercise, attended by approximately 30 insurance executives in Times Square, simulated a scenario where a Chinese cyberattack simultaneously disabled 5,000 U.S. water utilities.
The war game, designed by a former strategist for the Cybersecurity and Infrastructure Security Agency (CISA), aimed to test reactions under a countdown clock. The simulated outcomes included burst water mains, hospital evacuations, and insulin shortages, highlighting the potential for severe societal impact.
The involvement of insurance executives in such a simulation underscores their critical, if often overlooked, role in national cybersecurity response. When organizations experience a cyberattack, their first call is frequently to their insurance provider. These providers then facilitate access to pre-approved lawyers and cybersecurity incident responders, effectively controlling the initial stages of a national response due to their financial backing of recovery efforts.
The persistent and widespread nature of Volt Typhoon's intrusions into U.S. civilian infrastructure represents a significant concern for cybersecurity experts and government officials. The group's apparent restraint in activating these "digital bombs" has, paradoxically, allowed their activities to remain somewhat under the radar, despite the severe potential consequences should they decide to launch a disruptive attack.
A weakness has been identified in Tenda CP3 27.5.57.101. This issue affects some unknown processing of the file Net/NetCheckPing.cpp. This manipulation of the argument interface_name/host causes os command injection. The attack can be initiated remotely.
A security flaw has been discovered in Tenda CP3 27.5.57.101. This vulnerability affects the function SystemAsh of the file Apis/system.c of the component Kylin. The manipulation of the argument AlarmVoiceURL results in os command injection. It is possible to launch the attack remotely.

OpenAI has announced a $1 billion commitment to provide subsidized access to its Daybreak AI cybersecurity tools for under-resourced critical infrastructure defenders. The initiative, named Daybreak for Frontline Defenders, will offer AI models, training, and technical support over the next six months, prioritizing water and wastewater utilities, electric grid operators, and local government entities. This move aims to equip organizations with limited budgets and staff against increasingly sophisticated cyber threats.

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an advisory published on September 5. Sansec, which discovered the flaw and named it StyleSmuggler, said attacks started on September 4. "Sansec is publishing early
