Chinese-linked hackers compromise ConnectWise, target hundreds in global attack, Microsoft says

A Chinese state-aligned hacking ​group used an AI-driven penetration testing ‌tool to ​compromise IT services firm ConnectWise as part of a campaign that targeted hundreds of organizations globally, Microsoft said on ‌Wednesday.

Based on Microsoft's analysis and evidence available to ConnectWise, "it appears that a China state-aligned group was responsible for the attack on ConnectWise Cloud Backup," ConnectWise CEO Manny Rivelo said in a ‌separatestatement. Rivelo said ConnectWise "contained the affected application connections and are restoring services in controlled phases," and ‌that "those actions do not remove unauthorized access that may have already been established within individual customer tenants, which require separate review."

The Chinese Embassy in Washington did not immediately respond to a request for comment. ⁠Beijing regularly ​denies conducting or condoning ⁠cyber-enabled data theft. The hackers, which Microsoft tracks as Storm-0940, used an open-source penetration testing framework called ARTEX ⁠to carry out the campaign, Microsoft said.

There are multiple tools used to conduct penetration testing, a form ​of legitimate testing of the security of networks or services. ARTEX allows users ⁠to use any AI model to automate a variety of penetration testing tasks and can be configured to run ⁠autonomous ​tasks including reconnaissance and data exfiltration, Microsoft said. The attack targeted organizations across a variety of sectors, including aerospace, defense, automotive, chemicals, energy, financial services, government, legal, manufacturing, media, military, ⁠semiconductor, software, technology, think tanks and non-profit organizations, Microsoft said.

While the majority of targeting ⁠was not successful, Microsoft ⁠said, Storm-0940 achieved privileged cloud persistence — or high-level access that could continue even after cleanup efforts — at many organizations in a brief ‌time.
