China Warns of Cybersecurity Risks from Foreign Technology Backdoors

Cybersecurity is of paramount importance in our increasingly digital world. It extends beyond personal privacy and corporate secrets, reaching into the realm of national security. A significant concern is the potential for information leakage stemming from maliciously embedded or intentionally designed backdoors, as highlighted by the Chinese Ministry of State Security (MSS).

A "technical backdoor" is a method that circumvents standard security measures to gain access to a program or system. Initially designed to aid developers in debugging or fixing vulnerabilities, these backdoors can be exploited by malicious actors if not promptly removed, posing significant security risks. They can provide unauthorized access to systems and sensitive data, according to the MSS.

Some foreign-made chips, smart devices, and software may be deliberately implanted with backdoors during their design or manufacturing. Manufacturers could remotely control these devices through specific signals, potentially activating cameras or microphones, or instructing the system to collect and transmit data, the MSS noted.

In certain instances, manufacturers may pre-set remote access backdoors in products to facilitate post-sale maintenance. While intended as a service, these backdoors can become hidden vulnerabilities if poorly managed or compromised, leading to the potential for spying and data theft, the MSS warned.

Furthermore, some malicious manufacturers may exploit software update channels, tamper with open-source code repositories, or alter code within the supply chain to plant backdoors during device usage, enabling illegal control or secret theft.

The security of smart devices and information systems is crucial for individuals and, even more so, for national security. The MSS suggests that key confidential positions should consider using independently developed chips and domestic operating systems to mitigate risks associated with foreign hardware or software backdoors.
