On Friday, Microsoft warned that cybercriminals are using the back doors Chinese hackers left behind to deploy ransomware, which is used to lock up computer systems until payment is made.
Businesses and government agencies in the United States that use a Microsoft email service have been compromised in an aggressive hacking campaign that was probably sponsored by the Chinese government, Microsoft said.
The U.S. government’s cybersecurity agency issued an emergency warning on Wednesday, amid concerns that the hacking campaign had affected a large number of targets. The warning urged federal agencies to immediately patch their systems. On Friday, the cybersecurity reporter Brian Krebs reported that the attack had hit at least 30,000 Microsoft customers.
Federal officials were struggling to understand how the latest hack compared with last year’s intrusion into a variety of federal agencies and corporate systems by Russian hackers in what has become known as the SolarWinds attack. In that incident, the Russian hackers planted code in an update of the SolarWinds network management software. While about 18,000 customers of the company downloaded the code, so far there is only evidence that the Russian hackers stole material from nine government agencies and roughly 100 companies.
In the hack that Microsoft has attributed to the Chinese, there are estimates that 30,000 or so customers were affected when the hackers exploited holes in Exchange, a mail and calendar server created by Microsoft. Those systems are used by a broad range of customers, from small businesses to local and state governments and some military contractors. The hackers were able to steal emails and install malware to continue surveillance of their targets, Microsoft said in a blog post, but Microsoft said it had no sense of how extensive the theft was.
