Backdoor attacks, a stealthy and insidious form of cybercrime, have become a significant concern for businesses of all sizes, including micro, small, and medium-sized enterprises (MSMEs). These attacks involve the insertion of unauthorized access points into software, systems, or networks, enabling attackers to bypass security controls and gain persistent access for malicious purposes.
Firmware vulnerabilities arise from security gaps in embedded software’s code or design. Adversaries can exploit these security risks.
Hackers can exploit a technique called ‘SurfingAttack’, which is a form of ultrasonic hacking, to issue silent commands to voice assistants in your devices (like smartphones).
The vulnerability lies in the IEEE 802.11 Wi-Fi standard, which is the set of rules that Wi-Fi networks follow. This standard doesn’t always require verification of the SSID during connection. When you connect to a Wi-Fi network, your device doesn’t always check if the network name (SSID) is legitimate. This creates an opening for attackers to:
