Although year after year, companies focused on cell phones improve their security in order to reduce attacks on their devices, there are still vulnerabilities in the system of some smartphones that are exploited by hackers.
This is revealed by a study by researchers at the University of Purdue and the University of Iowa, which reveals that, around ten models of the most popular Android phones, can be hacked in a simple way.
According to the study, attackers can intercept calls, divert calls to another phone or block all phone calls and Internet access from the device.RELATED
This is done through a USB or Bluetooth connection. In this sense, the vulnerabilities are hosted in the software, baseband, which allows the telephone modem to communicate with the cellular network, which makes it possible for the device to make calls or connect to the Internet.
Generally this baseband is protected with security protocols to prevent third parties from taking control of the device, however, researchers discovered that several Android phones without realizing allow Bluetooth and USB accessories, such as headphones or smartwatch, to access That base band.
Syed Rafiul Hussain and Imtiaz Karim, two co-authors of the investigation, revealed to the site specialized in TechCrunch technology, that the impact of these attacks ranges from the exposure of private user information, to the possibility of leaving that equipment completely incommunicado.
These are the phones that can present this type of vulnerability, according to the study:
Samsung Galaxy S8 +
Samsung Galaxy s3
Huawei P8 Lite
Huawei Nexus 6P
Samsung Note 2
Google Pixel 2
LG Nexus 5
Motorola Nexus 6
HTC Desire 10 Lifestyle
According to TechCrunch, the problem can be solved with an update, but not all brands are ready for updates. At present, Samsung and Google mentioned that, with the latest security updates, this vulnerability should no longer exist, however, no other manufacturer has said anything about it.
