Chinese Hacking Group Uncovers Sophisticated Backdoor in 42 Countries

In a recent report, Google revealed that a Chinese hacking group known as UNC2814 had infiltrated telecommunications and government groups in at least 42 countries, likely to spy on specific individuals. The group's activities have been tracked by Google since 2017, but the latest campaign was discovered after the company's security software flagged suspicious activity on a customer's Linux-based server.

Google's investigation led to the discovery of a sophisticated backdoor called Gridtide, written in the C programming language and designed to target Linux-based software. The backdoor can remotely execute commands and download and upload files, using a legitimate API in Google Sheets as a disguised communication channel to receive commands and send data to the Chinese hackers.

To evade detection, UNC2814 has been found to use various tactics, including exploiting web servers and edge systems to gain access to victim networks. The group's activities are believed to be focused on exfiltrating personal information, such as names, phone numbers, and national ID numbers, which would enable clandestine efforts to surveil targets.

Google has taken steps to shut down the spying campaign, including terminating the hacking group's access to the Google Sheets API and other company products. The company has also issued formal victim notifications, providing technical details about UNC2814's backdoor and the group's other tactics, including the use of a VPN component.

The discovery of UNC2814 highlights the ongoing threat posed by Chinese state-sponsored hackers, who have been linked to numerous high-profile data breaches and espionage campaigns. The group's activities bring to mind Salt Typhoon, another notorious Chinese hacking group that infiltrated telecommunications companies to spy on politicians, including Donald Trump's phone.

However, Google suspects that UNC2814 operates as a separate entity from Salt Typhoon, targeting different victims globally using distinct tactics, techniques, and procedures. The scope of UNC2814's activities is remarkable, with the group having gained access to at least 42 countries, including North America, where no data breaches were reported.

The investigation into UNC2814's activities has been ongoing since 2017, when Google first detected the group's presence in the wild. Since then, the company has worked tirelessly to monitor and mitigate the group's activities, but the latest campaign has highlighted the need for continued vigilance in the cybersecurity community.

In conclusion, the discovery of UNC2814 highlights the importance of staying vigilant in the face of state-sponsored hacking threats. As cybersecurity professionals, it is essential to stay informed about emerging threats and to take steps to protect ourselves and our organizations from these types of attacks. By working together, we can help to prevent data breaches and espionage campaigns like those carried out by UNC2814.
