Motorola phones with the Unisoc chip have been found to be vulnerable to hacking.
Three Motorola smartphones are said to be vulnerable to the attack that prevents users from using the LTE network on their smartphones. The Unisoc chip that Motorola has used in three of its smartphone models – Moto G20, Moto E30 and Moto E40 smartphones are vulnerable to these attacks. Unisoc takes a fair share of the budget smartphone market. It is the fourth largest chip maker in 2021 after MediaTek, Qualcomm and Apple with 11 percent market share. However, a recent report from Checkpoint Research has highlighted that Unisoc chips have a critical security vulnerability, which makes them vulnerable to hacking.
The Unisoc T700 chip was used in three Motorola devices from last year – the Moto G20, Moto E30 and Moto E40. The chips were found to have a serious security flaw, named CVE-20210-2022. Checkpoint already reported it to Unisoc last month and the company rated the flaw to be at critical risk of 9.4 out of 10, and patched the vulnerability. The researchers said they discovered the flaw while clearing Non-Access Stratum (NAS) message handlers in the chip’s modem firmware. This vulnerability could render the chip’s cellular communication capabilities neutral or completely inoperable. Also Read: Motorola Edge 30 review: It lacks an edge over its competitors
Salva Makkaveev, reverse engineering and security attorney at Checkpoint Research, said, “The attacker could have used a radio station to send a corrupted packet that would reset the modem, denying the user the ability to connect. If the cellular connection is not patched, the attacker could block it.” . The vulnerability can be used to disrupt a device’s wireless communications through a corrupted packet. “A hacker or military unit could take advantage of such a vulnerability to neutralize communications at a specific location,” CheckPoint Research added.

Those using a Unisoc-powered smartphone are advised to update their device to the latest OS version to avoid such vulnerabilities. Although there is nothing Android users can do at the moment, they need to make sure to apply the patch that Google will release in the upcoming Android security bulletin.
