China MALWARE Hits Guam to Affect any U.S. Military Aid to Taiwan
Chinese Malware Hits Systems on Guam. Is Taiwan the Real Target?
The code, which Microsoft said was installed by a Chinese government hacking group, set off alarms because Guam would be a centerpiece of any U.S. military response to a move against Taiwan.
BBC 25 MAY 2023
The Great Hall of the People in Beijing. Telecommunications networks are key targets for hackers, and the system in Guam is particularly important to China
Around the time that the F.B.I. was examining the equipment recovered from the Chinese spy balloon shot down off the South Carolina coast in February, American intelligence agencies and Microsoft detected what they feared was a more worrisome intruder: mysterious computer code appearing in telecommunications systems in Guam and elsewhere in the United States.
The code, which Microsoft said was installed by a Chinese government hacking group, raised alarms because Guam, with its Pacific ports and vast American air base, would be a centerpiece of any American military response to an invasion or blockade of Taiwan.
The operation was conducted with great stealth, sometimes flowing through home routers and other common internet-connected consumer devices, to make the intrusion harder to track.
The code is called a “web shell,” in this case a malicious script that enables remote access to a server. Home routers are particularly vulnerable, especially older models that have not had updated software and protections.
Unlike the balloon that fascinated Americans as it performed pirouettes over sensitive nuclear sites, the computer code could not be shot down on live television. So instead, Microsoft on Wednesday published details of the code that would make it possible for corporate users, manufacturers and others to detect and remove it.
In a coordinated release, the National Security Agency — along with other domestic agencies and counterparts in Australia, Britain, New Zealand and Canada — published a 24-page advisory that referred to Microsoft’s finding and offered broader warnings about a “recently discovered cluster of activity” from China.
Microsoft called the hacking group “Volt Typhoon” and said that it was part of a state-sponsored Chinese effort aimed at not only critical infrastructure such as communications, electric and gas utilities, but also maritime operations and transportation.
The intrusions appeared, for now, to be an espionage campaign. But the Chinese could use the code, which is designed to pierce firewalls, to enable destructive attacks, if they choose.
So far, Microsoft says, there is no evidence that the Chinese group has used the access for any offensive attacks. Unlike Russian groups, the Chinese intelligence and military hackers usually prioritize espionage.
