New Qualcomm Chip Bug Could Let Hackers Spy On Android Devices

Cybersecurity scientists have disclosed a new safety vulnerability in Qualcomm’s mobile station modems (MSM) that could possibly permit an attacker to leverage the fundamental Android running program to slip malicious code into cell phones, undetected.

“If exploited, the vulnerability would have authorized an attacker to use Android OS alone as an entry level to inject destructive and invisible code into telephones, granting them obtain to SMS messages and audio of cellphone conversations,” researchers from Israeli safety company Look at Place stated in an investigation printed nowadays.

The heap overflow vulnerability, tracked as CVE-2020-11292, could be exploited by a destructive app to conceal its actions “beneath” the OS in the modem chip by itself, as a result earning it invisible to the functioning program and the protection protections built into it.

Made given that the 1990s, Qualcomm MSM chips enables mobile phones to join to mobile networks and allow Android to just take to the chip’s processor via the Qualcomm MSM Interface (QMI), a proprietary protocol that allows the interaction amongst the program parts in the MSM and other peripheral subsystems on the gadget such as cameras and fingerprint scanners.

Although 40% of all smartphones nowadays, like these from Google, Samsung, LG, Xiaomi, and One Moreover, use a Qualcomm MSM chip, an estimated 30% of the products arrive with QMI in them, according to analysis from Counterpoint.

“An attacker could have made use of this vulnerability to inject destructive code into the modem from Android, offering them accessibility to the gadget user’s connect with historical past and SMS, as properly as the potential to listen to the product user’s conversations,” the researchers mentioned. “A hacker can also exploit the vulnerability to unlock the device’s SIM, thereby beating the restrictions imposed by assistance companies on it.”

Examine Stage reported it notified Qualcomm of the issue on Oct. 8, 2020, adhering to which the chipmaker notified applicable cell suppliers.

“Delivering technologies that assist robust safety and privacy is a precedence for Qualcomm,” the firm advised The Hacker Information by way of email. “Qualcomm Technologies has previously built fixes obtainable to OEMs in December 2020, and we persuade finish end users to update their equipment as patches turn into obtainable.” The business also reported it intends to incorporate CVE-2020-11292 in the public Android bulletin for June.

This is not the to start with time critical flaws have been found in Qualcomm chips. In August 2020, Look at Position scientists disclosed much more than 400 security troubles — collectively named “Achilles” — in its electronic signal processing chip, enabling an adversary to flip the phone into a “fantastic spying device, with out any user interaction required.”

“Mobile modem chips are often deemed the crown jewels for cyber attackers, especially the chips created by Qualcomm,” reported Yaniv Balmas, head of cyber analysis at Verify Place. “An attack on Qualcomm modem chips has the possible to negatively influence hundreds of millions of cellular telephones throughout the world.”
