One of the most serious problems that we can find in our devices is the unwanted access of intruders. They can take control of the device, read messages, view content that we have saved… That is what happens with this serious error that we echo and that allows an attacker to steal your audio, images or videos that you have stored on your mobile. We will explain what you should do to avoid it.

A serious bug exposes your media files

This is a bug that affects Android and, according to the security researchers behind this discovery, it affects devices that use Qualcomm and MediaTek chips. These devices are vulnerable to remote code execution due to a flaw in the Apple Lossless Audio Codec implementation. It is a format for encoding audio without loss of quality.

Keep in mind that these two chip manufacturers that are affected by this problem are among the most common. This makes the problem likely to affect millions of users around the world.

Although at the moment they have not given many details about the problem, they have indicated that this vulnerability allows an attacker to execute code remotely by sending a malicious audio file. This puts them in control of your media files, so they could steal anything on your device.

In total there are three bugs that have already been patched by Qualcomm and MediaTek. These are the vulnerability registered as CVE-2021-0674 and with a danger score of 5.5, vulnerability CVE-2021-0675 with a score of 7.8 and, the most critical of all, CVE-2021-30351 with a score of 9.8.

What to do to avoid the problem

As we have indicated, these vulnerabilities have already been patched by Qualcomm and MediaTek. In fact, it was something they already did last December. Therefore, the most important thing is to make sure that you have the latest versions installed on the Android system. This is essential both for optimal operation and for resolving security flaws that appear. You must install the December or newer Android patches.

However, we have seen that this attack can be executed by sending a malicious audio file. It is also essential to maintain common sense and be careful with what files, whether audio, video or image, you open. For example, it is a mistake to download any document that arrives by mail or through social networks without knowing if it is really reliable. If you receive something from an unknown source, it is best not to open it.

In addition, it is interesting to have security applications. A good antivirus can prevent the entry of malware and thus reduce the risk that your personal data may be compromised. There are many options available, both free and paid. Protecting the security of any device is essential to avoid network problems.
