Three Motorola smartphones are at risk of being hit by an attack that prevents users from using LTE networks on their smartphones. The issue stems from the Unisoc chip that Motorola has installed in three of its smartphones – the Moto G20, Moto E30 and Moto E40 smartphones.
unisockWhich is taking a good share of the budget smartphone market, was the fourth largest chip maker in 2021 mediatek, QualcommAnd Apple With 11 percent market share. Now, a report by Checkpoint Research has found a vulnerability that can be used to deny modem services and block communications on the Unisoc chip.
The chip named Unisoc T700 chip is used for three . is done in motorola Last year’s equipment – moto g20, Moto E30, and Moto E40 chipsets. Checkpoint notified Unisoc last month and the company has patched the vulnerability, evaluating the flaw to a critical risk of 9.4 out of 10.
“In this study, we first looked at the UNISOC baseband as an attack target. We scanned NAS message handlers within a short time frame and found a vulnerability that could be used to intercept a device’s radio communications via a malformed packet. A hacker or a military unit can take advantage of such a vulnerability to neutralize communications at a specific location,” Checkpoint Research said in its report.
Now, chip-level vulnerabilities are quite common on smartphones. Smartphone modems are a prime target for attackers, Checkpoint Research said, because it can be easily accessed remotely via SMS or radio packets. Those using Unisoc-powered smartphones are recommended to update their device to the latest OS version. Google has said that it will publish a new patch in an upcoming Android security bulletin.
